Topic: Color symbol of line chart

Posted by deweb · 12-06-2024 - 08:14

Good morning

I created a lineChart type chart with 2 line series.
The chart works great. However, I try to customize the colors. I can modify the color of the line, but I cannot modify the color of the point (symbol).
I still have a PHP error:

Call to a member function setAttribute() on null

FCPATH/phpdocx/classes/CreateGraphic.php at line 919

I have a premium version and here are my chart settings :

$data = array(
                                'legend' => array('Serie 1', 'Serie 2'),

Hello,

The current stable version of phpdocx doesn't include an option to set custom color symbols. A new option must be added (symbolRgbColors or a similar option name). It's currently being developed and it will be included in the next stable release of phpdocx (there's no release date).

Regarding the PHP error you get, it comes from a not supported theme option when generating combo charts. In this case, please do not create custom color for values, only for series:

$paramsChart = array(
    'data' => $data,
    'type' => 'lineChart',
    'symbol' => 'dot',
    'symbolSize' => 5,
    'smooth' => false,
    'returnChart' => true,
    'color' => 2,
    'theme' => array(
        'serRgbColors' => array('00b546','fa7d0f'),
    ),
);

We have opened a task to the dev team to support setting custom color to individual values when adding a combo chart.

Regards.

Thank you for your reply !
I'm going to disable the symbols in the meantime!

Good day !
