Description
I did leave the global background color field empty, because I need a pie chart and a bar chart with different background colors. But how can I manually set a background color for every chart?
'#chart_fill' => chart_fill('c', '000000'),
This doesn't work for the whole background when using for bar chart. For the pie chart this code doesn't work at all.
So how can I set a seperate background color for every chart??
Thank you.

Hmm chart fill shoooould work.. BUT tthat being said I may have done crappy validation on wither or not the global bg was set, meaning "" may be set if I did not properly check things. You might want to try variable_del to remove it preceding your other code.

thanks for your answer. but what do you mean with "variable_del"? how should I implement this? how should I use this?
here is my current code:
$chart = array(
'#chart_id' => 'test_chart',
'#type' => CHART_TYPE_BAR_H,
'#size' => chart_size(274, 65),
'#bar_size' => chart_bar_size(30, 5),
'#chart_fill' => chart_fill('c', 'ff0000'),
);
$chart['#data']['benutzt'] = array(10);
$chart['#data']['ungenutzt'] = array(90);
$chart['#data_colors']['benutzt'] = '4a7e00';
$chart['#data_colors']['ungenutzt'] = 'e5eac0';
$chart['#mixed_axis_labels'][CHART_AXIS_X_BOTTOM][1][] = chart_mixed_axis_label('0%');
$chart['#mixed_axis_labels'][CHART_AXIS_X_BOTTOM][1][] = chart_mixed_axis_label('25%');
$chart['#mixed_axis_labels'][CHART_AXIS_X_BOTTOM][1][] = chart_mixed_axis_label('50%');
$chart['#mixed_axis_labels'][CHART_AXIS_X_BOTTOM][1][] = chart_mixed_axis_label('75%');
$chart['#mixed_axis_labels'][CHART_AXIS_X_BOTTOM][1][] = chart_mixed_axis_label('100%');
echo chart_render($chart);
this is how it looks: http://img149.imageshack.us/img149/6620/unbenannt1nf7.gif
do you see what I mean? I do need the whole background in the chart_fill color. right now only the inner part of the background gets the chart_fill color. the rest is white, when no global background color is entered.
when I use the global setting for background color, the chart fill color will be ignored and the whole background will be filled with the global background color. But I do need to set different background colors to different charts, so the global setting doesn't work for me.
Any solution? Any Patch to specify a background color for a chart id? I would really appreciate your help.
Thank you.

i looked at the google api settings:
'#chart_fill' => chart_fill('bg', 'ff0000'),this is your friend!;)
