In case you need to pass null values to generate non linear data rows, you can't since the class simply discards empty or null values.

This is the fix for the moment: [file:application/library/highcharts.php:343]

public function push_serie_data($value = '', $serie_name = ''){

    if ($serie_name AND $value)
    {
        $index = $this->find_serie_name($serie_name);

        $value = (is_numeric($value)) ? (float)$value : $value;

        $this->opts['series'][$index]['data'][] = $value;
    } else {
        if($value===NULL) {
            $index = $this->find_serie_name($serie_name);
            $value = null;
            $this->opts['series'][$index]['data'][] = $value;
        }
    }
    return $this;
}

How I can display two Y Axes in one graph?

I want to show something like this:

http://www.highcharts.com/demo/combo-multi-axes

Hello,

i want to show the real time live data that fetched from db (My DB data is keep on inserting )

I have 5 table 't1,t2,t5,t4,t5' . This will get updated in each sec or two .
So i want to show the total data in each table using line graph .How can i do this ???

How can I use a Range Selector (https://www.highcharts.com/docs/chart-concepts/range-selector) and how to enable datalabels in a bar chart

As here in js?

  PlotOptions: {
         Column: {
             Stacking: 'normal',
             DataLabels: {
                 Enabled: true,
                 Color: (Highcharts.theme && Highcharts.theme.dataLabelsColor) || 'White'
             }
         }
     },

thank you!!

Im sure template function have bugs.

1. this code make some error in template function :
   
   $this->highcharts->set_serie_options(array('type' => 'spline'), 'Another description');
   when i delete this line, template function is work.

the way function active_record display chart with template (second chart) have a bug. I try to change the code like this :

function _data()
    {
        $data['users']['data'] = array(536564837, 0, 153309074, 99143700, 82548200);
        $data['users']['name'] = 'Users by Language';
        $data['popul']['data'] = array(1277528133, 0, 420469703, 126804433, 250372925);
        $data['popul']['name'] = 'World Population';
        $data['axis']['categories'] = array('English', 'Chinese', 'Spanish', 'Japanese', 'Portuguese');
        return $data;
    }

i change the second value into '0', and this is what i get :

'0' value didnt show, and displaying categories suppose to be 5, not 4.

I would like to create driilldown chart. Is it possible with this library?

Hi im wondering how would you use the JSON output you created on the library.
Im trying to use this JSON to create and populate the chart using just javascript & getJSON

how to use highchart's dataLabel formatter ?

using following syntax I get two $ char before and at the end of the function:
..
array = ('formatter' => "function() { return this.y }")

in html source code:
"formatter":"$$function() { return this.y }$$"

I get no errors but the formatter doesn't seems to work

thanks

Can't use accented characters for labels or titles, for example using letter "é" I got "u009C" rendered. Using a jsfiddle example of highchart, entering there letter "é", renders well.

Line 34 if libraries/highcharts.php:

"enable" should be "enabled"

'credits' => array(
'enabled'=> true,
'text' => 'test',
'href' => ''
),
