hello supportteam,

currently I have to add some charts to my document and I have 3 questions on which I didn't find an answer in the forum respective the API documentation.

 

1. For me it is very important to give each data-element of a pie- oder bar-chart a seperate color which I read from a database. Is there a way to do it like the following codesample illustrates (which maybe overules the color-property of the addChart-parameters)

If there is no way yet, would it be possible to add this as a feature in a later version of phpdocx?

$data = array(
    'data' => array(
        array(
            'name' => 'Legend 1',
            'values' => array(20),
            'color' => 'ff0000',
        ),
        array(
            'name' => 'Legend 2',
            'values' => array(30),
            'color' => '00ff00',        
        ),
        array(
            'name' => 'Legend 3',
            'values' => array(40),
            'color' => '0000ff',
        ),
    ),
);

2. Is it possible to style the font of the legend (which font, size, color, attributes like bold, italic) ? The size is very important for me because of people with vision impairment.

3. Which are the possible Values for the formatCode - property of the addChart() - method? I didn't find any description or samples.

thanks in advance

Siegfried
