Graph Lines get rendered 1px too far left

If you look closely at any rendered graph, the lines start on the left
border not inside it.

Could you add in a value to invert whatever axis eg:

xaxis, yaxis: {
    invert: true
}

Flot Ext Js : loosing line colors when dragging

Hello everybody,

I try to use flot with Ext js, including a chart in a gadget but when I'm
moving my gadget in the window I loose the colors for my lines (only with
IE7, it works fine with Firefox).

Any idea about how to fix that?

Thanks a lot in advance

Support for bar charts with keys instead of x-axis values

I'm using Flot on SVN, or by the way Flot 0.3. Firefox 2 on Ubuntu.

When giving more the one serie with "bars : {show : true}" I see the bars
of the different series for the same x-value overlapping : I mean the bars
are one on each other. Is there any way (ie. any "bars" option) to say to
draw the bars one next to eachother for the same x-value instead?

I read more times the API, the issues, the samples and whatever but I
couldn't find anything that could help me.

Thank you.

Labels for X and Y axis

is there any way for displaying labels for X axis and Y axis?

Legend colors do not print

What steps will reproduce the problem?
1. Create a chart with legends
2. Print it (or use print preview)

What is the expected output? What do you see instead?
I expected to see the colored boxes that correspond to the trace colors. 
Instead the legend label boxes are white.

What version of the product are you using? On what operating system?
 - Flot 0.4.
 - Firefox 3.0rc1, IE 6, IE 7 (on Win XP)
 - Firefox 2.0.0.11 (on Linux)

Please provide any additional information below.
Unfortunately the background colors set with CSS don't print (unless the
user overrides a setting on their browsers).
I think you have to either make the legend labels be canvas tags or use the
colored border cheat.  In the example below, the top div is the same as
your legends, the bottom one uses the margin color trick to make printable
blocks:


<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<body>

<ul>

<li> <div style="overflow: hidden; width: 14px; height: 10px;
background-color: rgb(175, 216, 248);"/> </li>

<li> <p><div style="overflow: hidden; width: 0px; height: 0px;
border-width: 5px 7px 5px 7px; border-style: solid; border-color: rgb(175,
216, 248);"/></li>

</ul>

Graph area appears larger than the div

What steps will reproduce the problem?
1. Place the target div inside another div of the same, or slightly larger, size

What is the expected output? What do you see instead?
- Scrollbars will appear.  There's some horizontal space that shouldn't be 
there off to the right.  
The vertical scrollbar appears to be present due to the horizontal scrollbar

What version of the product are you using? On what operating system?
- 0.3 on OSX Leopard in Safari and Firefox.


Please provide any additional information below.
- Modify examples/real-data.html around line 15 as follows:

    <div id="placeholder2" style="overflow:auto;width:601px;height:301px;">
        <div id="placeholder" style="width:600px;height:300px;"></div>

grid borderWidth bug

What steps will reproduce the problem?
1. Set the grid borderWidth value to 0
2. Using a date range picker (x-axis = time) select a few date ranges
3. The displayed date range becomes innaccurate

What is the expected output? What do you see instead?
borderless grid that doesn't forget its bounds

What version of the product are you using? On what operating system?
latest release on Windows Firefox 2.0.0.14

Please provide any additional information below.
It seems to be an issue with the grid border being taken into account with
the calculations. Perhaps if this could be turned into a CSS border eg. on
a div behind the graph or alternatively add a gridBorderColor parameter so
it could be set to white. The former of these suggestions would help to
remove borderwidth calculations from the plotting process so may be
beneficial in more ways than one.

Thanks,
Rob

Strings as Ticks scaling

You demonstrate that it is fine to specifically set the tick positions and
set them as strings.

For example I have dates in an array and am setting the ticks on the xaxis
like so:

xaxis:{
ticks: [[0, allLicenseDates[0]], [(0.045*4), allLicenseDates[4]],
[(0.045*8), allLicenseDates[8]], [(0.045*12), allLicenseDates[12]],
[(0.045*16), allLicenseDates[16]], [(0.045*21), allLicenseDates[21]]]
}

So a string of “Dec 6” appears at 0 on the x-axis.  However, this
introduces overflow outside the margins in the graph if I dont calculate it
correctly. I would rather let Flot handle the spacing and scaling of the
graph instead of setting it myself so that the graph is more flexbile. 
When I try to set it myself, the graph goes outside of its margins.  

What syntax should I use for specifying strings on the x-axis and letting
Flot do the spacing/scaling?

Support for stacked bars.

It seems that it is not possible to create a graph with stacked bars. Like
this one: http://www.fusioncharts.com/free/Images/GalleryIcons/5/4.gif

It would be nice if it could! Thank you for considering this.

Plot area disappears in Firefox for large viewport sizes

I have a graph that is 520 x 300. The window viewport size is 1441 X 999
(reported through Web Developer toolbar). When I resize the viewport past a
height of 999, the plot area disappears while axis labels and legend
remain. The graph starts 400px down the page.

I'm using Flot 0.3 on Mac Firefox 2.0.0.11 with jQuery 1.2.1. The problem
does not occur on Safari, Windows IE, or Windows FF.

This is probably a low priority bug.

Additive Chart Support

It would be nice to add additive charts. An additive chart will sum the
values of more than one item. The chart could be used for looking at the
production of a set of companies during a set of years. Viewers could then
see each companies production, but also the total production.

Examples don't work in Konqueror 3.5.8

What steps will reproduce the problem?
1. Try to view examples in Konqueror

What is the expected output? What do you see instead?

Expected to see graphs, see blank areas instead

What version of the product are you using? On what operating system?

Konqueror 3.5.8, Kubuntu 7.10

Please provide any additional information below.

I'm not sure on the extent of Konqueror's support of the canvas tag. Also
Konqueror support is probably not a priority and it may be interesting to
see what Konqueror in KDE 4 brings. It would however be nice to support
Konqueror if it's possible without too much work.

Ticks are not centered on bar graphs

What steps will reproduce the problem?

What is the expected output? What do you see instead?
I expected to see the ticks centered under each bar. They were instead
centered under the vertical line, which is the beginning of each bar. It is
hard to see which label belongs to which bar especially if they are long
labels.

weekend highlighting in visitors example broken by daylight savings change

What steps will reproduce the problem?
1. create a graph based on visitors.html example (see attached
visitors_with_DST.html)
2. note xmin at Friday April 4 2300, xmax at Saturday April 5 0200


What is the expected output? What do you see instead?

The weekend (Saturday) appears to start at 0100 instead of 0000 hours.


What version of the product are you using? On what operating system?

Any / Any


Please provide any additional information below.

This problem occurs because:

- we can see hourly data
- the previous weekend started without Daylight savings time
- the current weekend in the view starts with Daylight savings time

fix:

change:
            i += 7 * 24 * 60 * 60 * 1000;
to:
            d.setDate(d.getDate() + 7);  // avoids daylight savings changes
            i = d.getTime();

Bars in mode "time"

Using SVN-Flot version with Firefox 2 on Ubuntu.

I'm using bars in "time" mode. What I get is one pixel width for each bar.
No way even if playing with xaxis.tickSize, xaxis.minTickSize, xaxis.ticks etc.

I see the "time" mode is something new....

Am I doing anything wrong?

really stupid serie :

    var data = [[(new Date(100000)).getTime(), 1], [(new

</code>

What is the expected output? What do you see instead?

Expected output is a graph of weight over time, but an infinite loop occurs
and the script must be stopped or the page hangs.

What version of the product are you using? On what operating system?
Using 0.4 on Ubuntu with Firefox 2

Please provide any additional information below.
It appears that this is due to flot generating a default "tickSize" for
this dataSeries of 0.5 and a default unit of "year".  This combination
causes an infinite loop due to line 523-525 of jquery.flot.js, which never
actually changes the date, and thus loops forever:

<code>
 else if (unit == "year") {
    d.setFullYear(d.getFullYear() + tickSize);
 }
</code>

I have fixed this locally by changing the above to:
<code>
 else if (unit == "year") {
    d.setFullYear(d.getFullYear() + (tickSize < 1 ? 1 : tickSize));
 }
</code>

What steps will reproduce the problem?
1. Insert sample code in an ASP.NET page with a master page
2.
3.

What is the expected output? What do you see instead?
Flot doesn't do anything, generates javascript error...  looks like the 
jquery.flot.js file was opened (threw a few alerts in it to test) but the 
$.plot function doesn't get created properly so calls to it fail.

What version of the product are you using? On what operating system?
Tested in Firefox and IE.

Create releases

Currently flot only has code in the trunk. It would be good to get "official" 
releases so that users 
can rely on the fact that they have a certain version rather than a randomly 
checked out revision of 
the file.

Support for XML Namespaces and some cosmetic changes

What steps will reproduce the problem?
1. Use flot on a non html page. (xml+?)

What is the expected output? What do you see instead?
It doesn't work at all because the tag canvas is not supported in said
namespace.

What version of the product are you using? On what operating system?
Mozilla Firefox 2.0.0.11, jQuery 1.2.1, Flot 0.2 on a XUL page.

Please provide any additional information below.

Solution:
Use of document.createElementNS('http://www.w3.org/1999/xhtml', 'canvas')
instead of typed HTML where supported.

1. Added support for Flot to coexist in a namespaced pages, if it doesn't
support document.createElementNS fall back to document.createElement Also
note I have added a div container under target so fixed absolute
positionment works in this cases. I have also replaced every instance of
innerHTML or typed HTML with their DOM equivalent functions so it should
work where typed HTML didn't.
2. Fixed alignment on legend cells where supported.
3. Tabs instead of spaces, it was previously mixed.

Tested on IE6, IE7, Firefox2. All examples work.

PLL.

Legends are multiplying

When I zoom (create a selection) legends in container are being multiply.
Here is a code which is working fine:

var options = {
            xaxis: { mode: "time" },
            selection: { mode: "x" },
            legend: {

        var plot = $.plot($('#'+divId), [timeLine_01, timeLine_02,
timeLine_03, timeLine_04, timeLine_05, timeLine_06], options);
        var overview = $.plot($("#overview"), [timeLine_01_complete,

timeLine_05_complete, timeLine_06_complete], {

            shadowSize: 0,
            xaxis: { ticks: [], mode: "time" },
            yaxis: { ticks: [], min: 0 },
            selection: { mode: "x" }
        });
        var internalSelection = false;
        $('#'+divId).bind("selected", function (event, area) {
            plot = $.plot($('#'+divId), [timeLine_01, timeLine_02,
timeLine_03, timeLine_04, timeLine_05, timeLine_06],
                          $.extend(true, {}, options, {
                              xaxis: { min: area.x1, max: area.x2 }
                          }));
            if (internalSelection) {
                return;
            }
            internalSelection = true;
            overview.setSelection(area);

            internalSelection = true;
            plot.setSelection(area);
            internalSelection = false;
        });

Attached screenshots are showing how legends are multiplying by creating a
selection (zoom).

How to stop multiplying legends in container if user create a selection?!

Graph must be rendered on page load.

The graph will appear blank unless rendered initially upon the page load.

The following code is an example that breaks it:

setTimeout(function() {
    $(function () {
        var d1 = [];
        for (var i = 0; i < 14; i += 0.5)
            d1.push([i, Math.sin(i)]);

        var d2 = [[0, 3], [4, 8], [8, 5], [9, 13]];

        $.plot($("#placeholder"), [ d1, d2 ]);
    });
},1000);

However, if you render the graph on page load, and then attempt to call
.plot afterwards it will update the graph with no issues.

Zooming too much freezes the script

What steps will reproduce the problem?
1. Go to the zooming example.
2. Keep zooming more and more smaller chunks (zoom within the zoom).

What is the expected output? What do you see instead?
I would expect it to stop me at some stage...?

What version of the product are you using? On what operating system?
Whatever is online on the examples page at the time of writing this entry.

Please provide any additional information below.
If I keep zooming at some stage the numbers on the axes become huge and
then all of a sudden the chart just freezes. After a while Firefox tells me
that a script is running in a loop and would I like to stop it.

excanvas missing from downloads

the Excanvas library for IE compatibility is missing from the downloads. 
It instead must be accessed via the subversion repository.  You may want to
add it to a zip download or package it as a separate download independent
of the repository

ParseInt Data

Could I suggest when Parsing data to graph, run the data through parseInt
or parseFloat. I spent 6 hours trying to figure out why the bar graphs
looked hideous to find that the data I was using that came out of PHP came
in string format. While the line graphs plot this fine, the bar graph has
trouble with barWidth. Parsing each x and y co-ordinate through parseInt()
did the trick for me. Note, I'm only testing on Firefox in a Linux enviroment.

Happy Graphing

labelWidth and labelHeight for axis settings do not work

What steps will reproduce the problem?
1. set labelWidth/labelHeight for x- or yaxis
2. nothing happens

What is the expected output? What do you see instead?
some change in the display of the labels

What version of the product are you using? On what operating system?
0.4

Please provide any additional information below.
I searched jquery.flot.js for labelWidth/labelHeight in order to check the
script but I did not find it. So I think it is not yet implemented. Am I right?

Actually I searched a way to remove the xaxis labels.

Odd behavior in Safari (both windows & mac) with other code on page

What steps will reproduce the problem?

1. use Google News bar wizard to create some code in the page - 
http://www.google.com/uds/solutions/wizards/newsbar.html?uds_o=0
2. insert some flot code
3. open the page - it won't generate the chart.  (if it does display 
chart, hit F5 - it'll probably disappear)
4. browse to flot samples pages; they will work
5. use back button to go back to test page - chart will now display
6. hit f5 to refresh - chart will disappear

You can look at http://dev.geoinvesting.com to see what I mean.  If I 
remove the Google newsbar code, the chart generates in Safari normally 
even after page refresh.

It seems to have something to do with the onload events...  it seems like 
Safari isn't running them properly.  I thought maybe Google's on load 
event was conflicting with Jquery, but even if I remove it (or embed their 
on load code after the flot setup) it doesn't make things better.

Support for arbitrary grid lines

Through the use of flot for some internal projects we've needed to show
'markers' on graphs, to indicate trends toward a value, etc.

I've made the change to support this in the source, changed the
'setting-options' example to use it and updated the documentation with a
quick note on it's use.

Please see the attached diff for inclusion/consideration.

I'm no 'canvas' expert so please feel completely free to alter the code in
any way that might be necessary.

Take care,
    Ryan

ps. Thanks for flot! It's awesome :)

Negative bars which go past the min of the y-axis are not shown.

What steps will reproduce the problem?
1. Place the attached file in the examples dir of the flot distribution and
open.

What is the expected output? What do you see instead?
The third bar has a value of -2, which is below the min y-axis value. Its
not shown on the graph. It should be.

What version of the product are you using? On what operating system?
Flot-0.4

Please provide any additional information below.

Problem is on line 1191-1194:
var left = x, right = x + barWidth, bottom = 0, top = y;

if (right < xaxis.min || left > xaxis.max || top < yaxis.min || bottom >
yaxis.max)
  continue;

On a negative bar, top is the bottom of the rectangle to draw, and bottom
is the top, so this logic fails. Top and bottom should be swapped so that
the clip code below this continues to work. For example, change 1191 from:
var left = x, right = x + barWidth, bottom = 0, top = y;
to:
var left = x, right = x + barWidth, bottom = (y < 0 ? y : 0), top = (y < 0
? 0 : y);

legend: labelFormatter = function(serie) Why serie is just the label, not the whole object

Excuse me if my explaination is not clear, i'm french ;-)

For example:
<code>
var testdata = [{ label: "Serie1",  data: 10},
        { label: "Serie2",  data: 30},
        { label: "Serie3",  data: 90},
        { label: "Serie4",  data: 70},
        { label: "Serie5",  data: 80},
        { label: "Serie6",  data: 110}];

$.plot(
    $('#myDiv'), 
    testdata,
    {
    ...,
        legend: {
        labelFormatter: function(serie){
            ...
            return serie;
        }
    }
);
</code>

In this example, serie is "Serie1" or "Serie2" or ... or "Serie6"
It would be great if serie was { label: "Serie1",  data: 10}

Don't you think?

Snap to ticks mode for the selection


This is an enhancement rather than a issue. The attached code is simply proof 
of concept and 
should be considered incomplete. 

Selecting ranges (selection-mode-x) is great but I wanted to make it easier to 
select the entire 
region between ticks. I wanted when I click the mouse and move for the current 
region to be 
selected and then as I cross over each tick the next region is selected in 
whole, rather than pixel 
by pixel. 

The patch as I said is little more than a proof, it doesn't work correctly 
going from right to left. 
There's a variable glob that's simply a placeholder, ideally this would be 
replaced by some 
configuration. I figured it was best to simply do a proof of concept to 
illustrate what I wanted, 
then as you guys have time/interest you can come up with a clean/proper 
implementation. 

Attached is an example screenshot and a patch.

Please provide any additional information below.

In some of the scientific graphs the values for x axis are uneven and plotted 
graphs provide the necessary information in that way only.
i.e. for values between 300 and 500 points are plotted for every 20 units. and 
For values from 500 to 3000 values are plotted for every 100 units and beyond 
3000 points are plotted for every 500 points. 
 Can we do this using current library easily

Problem creating charts with bars

Hi!

I tried to find out the best way to create a chart with bars.

I use the following statement to declare the data:

{data: [[0,28], [0,28]],label: “label goes here”,bars: {show: true } },

I think it is a little bit redundant to specify [0,28] twice, but if I try
something like
{data: [[0,28]],label: “label goes here”,bars: {show: true } },
only the legend is shown, but no bars. What am I doing wrong?

(maybe it is a stupid question because it works if I use the first
statement, but it seems to me that even the bars are painted twice, so the
colors (originally pastel colors) are much darker.

Best regards!
