gadfly.jl's Issues

ERROR: no method classify_data(DataArray{Float64,2},)

Hi!

I found this error on my latest Julia:

Julia Version 0.2.0-714.r1840
Commit 184054dcde 2013-03-24 16:23:04
Platform Info:
  OS_NAME: Linux
Using: (64-bit interface)
  Blas: libopenblas
  Lapack: libopenblas
  Libm: libopenlibm

Here the example I found when I tray to do a simple x,y scatterplot:

julia> data
91x2 DataFrame:
         contactos  rmsd
[1,]           0.0 0.073
[2,]           0.0 1.677
  :
[90,]         17.0 0.544
[91,]         18.0 0.479

julia> plot(data,{:x => "contactos", :y => "rmsd"},Geom.point)

Best!
P.S.: Maybe would be great have a simple default scatterplot version for a simple call like plot(x::Vector,y::Vector)

Attempts to use `spy` fail

perhaps due to operator error. What I tried was

julia> srand(1234321)

    [1 , 10]  =  0.601021
    [2 , 10]  =  0.804712

Issue with Gadfly plot function not defined.

Hi, I installed Gadfly with Pkg.add("Gadfly") and this was done without a hitch, but when issuing using Gadfly:

WARNING: parse_int is deprecated, use parseint instead.

is returned and typing plot in the REPL to see if the function is defined returns

julia> plot
ERROR: plot not defined

This means when I get to using plot() in the examples I can't go on.
There are no errors installing the package so I'm not sure why this is.

Best,
Ben.

If you can split a plot() function and a embed() fuction, or something similar.
Can be great if plot() fit to screen, and embed() still in the way there is, or maybe a little smaller [ some blogger's blog columns are a little more small than plot wide ].

latest 0.2 causes color to fail loading...

Gadfly.weave is broken due to changes in the julia process api

Note to self.

Add Base.writemime methods for export

Would be great to add a writemime(io, ::@MIME("text/html"), p::Plot) method to render to HTML.

@loladiro and I got a simple version of this working a few days ago in IJulia, and it was pretty cool. (I don't have the code on this machine, though; I can get it tonight from my laptop if need be). Basically, it did three things:

At the beginning (when Gadfly is loaded?), do display("text/html", """<script src="http://d3js.org/d3.v3.min.js" charset="utf-8"></script>""") to load the D3 library from the web. Be sure to catch MethodErrors in case the current displays do not support HTML output. You may want an init_display(d::Display) = .... to do the same thing for an arbitrary Display in case the user wants to set up D3 on a new display later.
Add a writemime function to display a Plot as HTML: just a script tag with the Javascript, and a div element with a random ID.

This was all that was needed to get clickable, interactive Gadfly plots in IJulia. Some other enhancements:

You might want plot to call redisplay on the Plot automatically, which will queue the plot for display in IJulia. Your draw function can call display to request immediate drawing (and IJulia will automatically remove the Plot object from the redisplay queue in this case).

One slight annoyance in our mock-up was that if I did plot again in a later IJulia input cell, it somehow added the plot to the previous output rather than in the new output. Possibly I just screwed something up with the div tag. If you want something to happen automatically at the end of each (multiline) input cell, e.g. drawing any plots that weren't yet drawn, or setting something up so that subsequent cells will create separate plots, you can do it with:

if isdefined(Main,:IJulia)
    Main.IJulia.push_postexecute_hook(my_hook)
end

where my_hook() is a thunk function.

Color schemes

Summary of the discussion started at JuliaLang/julia#2278:

@pao wrote:

Picking good colors is an old problem, but see e.g. http://colorbrewer2.org/. Or perhaps port @timholy's MATLAB code up on File Exchange http://www.mathworks.us/matlabcentral/fileexchange/29702

@dcjones:

That's interesting. I have a lot of color spaces implemented, but haven't spent a lot of time on actually selecting colors. I'm just choosing equidistant hues in LAB space.

@timholy:

@dcjones, your algorithm sounds quite similar to the one I developed. The main difference possibly being that you can ask it to avoid the background (or multiple other "reserved" colors).

@dcjones:

You're also not fixing chroma and lightness like I am. It makes sense to vary only hue (or only lightness) to show quantitative data, but qualitative scales like this might benefit by choosing from a wider range of colors.

I might try adding colorbrewer's scales, but I tend to prefer algorithms to anything "hand curated". If anyone knowns of any papers on maximizing distinguishability with constraints for colorblindness (and maybe printability), I'd be interested.

@pao:

I didn't do a deep search to see what ColorBrewer is doing behind the scenes--I can't imagine those were all created by hand, but maybe they were? Penn State is mentioned in the footer, so there might be some publications.

d3 backend x axis scaling breaks

The javascript output by draw(D3(...)) is generating bad x-axis scaling code for some data. I've attached some output from a recent plot. Here's an example scale function it generates:

.attr("cx", function(d) { return d[0] * 0 + 29.15; })

See data below:

Hi,

I managed to add additional gems but not mappings without an error:

julia> p = plot(mpg, x = "cty", y = "hwy", Geom.point)
julua> push!(p.layers, layer(Geom.line))
julia> push!(p.layers, layer(x = "displ", Geom.line)) 
ERROR: no method Dict((Symbol,ASCIIString),)

new sort api breaking gadfly :(

I had the same issue with my own code.

Then if I close julia I can move it and display it.

How get and easy to embed version of interactive plots

How I can get a easy copy&paste code for publish on my blog a Gadfly's interactive plot.
Maybe can be great an embed() for send to the clipboard that needed code (?)
Thanks!

Things currently wrong with panning/zooming.

Line size should be invariant.
Crosstalk with subplots or stacked plots. (Zooming one zooms them all.)
Zooming/panning works on categorial axis, which doesn't really make sense.
New grid lines and labels should be made if zooming causes the scale to dramatically change.
Plot serializations should be able to be modified so that the plot can be redrawn with the same viewport.

plotting histograms with different colors?

Sorry, this is more a question than an issue.

Is there some way to plot histograms with of different groups via color?

plot(df, x = "score", color = "target", Geom.bar)

This works for scatter plots

plot(df, x = "score", y = "duration", color = "target", Geom.point)

Implement a hexagonal binning geometry. See:

It would be great if the dependencies on Cairo and Fontconfig could be removed, from an ease of installation perspective.

vstack interface

I like the syntax plot([f, g], a, b) and find wish that vstack had the same interface:

Gadfly.vstack(ps::Vector{Plot}) = Gadfly.vstack(ps...)

It makes the calling a bit more verbose, but more consistent. Would you entertain adding and exporting this so vstack can be called without explicitly loading Compose?

Basic arithmetic issue

false

When I type 10.3 * 3 I get 30.900000000000002 instead of 30.9, I'm no expert but I don't get this when I type it into R and I suspect something is wrong.

Trying to execute the sample from demo.md - running into the above problem.

Plot does not display in browser and draw gives error.

I am using Safari 6.0.2. Good news is that when I try the julia 0.1 mac binary, Pkg.add("Gadfly") goes through error-free (although it is amazing how many packages it pulls in).

I then try the simplest example from overview as a sanity check:
p = plot([sin, cos], 0, 25)

A Finder window opens up with a temp file, and a new browser tab opens up, but it is empty. Trying the draw command after plot leads to an error:

julia> draw(SVG(6inch, 3inch), p)
ERROR: draw not defined

Error trying to use Gadfly on master

Hi,

I am seeing the following error while trying to use Gadfly.

Aesthetics based on shape

In particular for the point geometry. See Wilkinson p. 281 which cites several others.

Deselect point when mouse go out of the plot area

Hi!

This is cosmetic
Is you past over a point, the point is selected.
But is you go out of the plot area, the same point is still select.
Maybe can be great if go out of the plot area breaks the point selection in order to see again all the plot.

Thanks!

updated JSON interface

The JSON.jl package was recently updated to change its API a bit (see JuliaIO/JSON.jl#35). In particular:

parse is now JSON.parse
print_to_json is now JSON.print
to_json is now json

I'm hoping to push this to METADATA soon (as version 0.2), so you'll want to update your package.
