How to specify the colors of the labels

A fellow posted a comment at the bottom of this page using a scatter chart with green / red labels, might want to check out his code

A little more followup to tjholowaychuk. It looks like you can style labels for only certain types of charts such as line, bar, radar, and scatter charts. You can check out more info from the google chart api: http://code.google.com/apis/chart/labels.html#axis_styles_labels

The code sample below (taken from - http://snippets.dzone.com/posts/show/5985) shows you how to use '#mixed_axis_labels' to pass through styling parameters:

$chart['#mixed_axis_labels'][CHART_AXIS_X_BOTTOM][0][] = chart_mixed_axis_range_label(0, $sqlcnt + 1);
$chart['#mixed_axis_labels'][CHART_AXIS_X_BOTTOM][1][] = chart_mixed_axis_label(t(' '));    
$chart['#mixed_axis_labels'][CHART_AXIS_X_BOTTOM][1][] = chart_mixed_axis_label(t('members'));
$chart['#mixed_axis_labels'][CHART_AXIS_X_BOTTOM][1][] = chart_mixed_axis_label(t(' '));    
 
$chart['#mixed_axis_labels'][CHART_AXIS_Y_LEFT][2][] = chart_mixed_axis_range_label(0, 1000);
$chart['#mixed_axis_labels'][CHART_AXIS_Y_LEFT][3][] =  chart_mixed_axis_label(t(' '));
$chart['#mixed_axis_labels'][CHART_AXIS_Y_LEFT][3][] =  chart_mixed_axis_label(t('flyDollars'));
$chart['#mixed_axis_labels'][CHART_AXIS_Y_LEFT][3][] =  chart_mixed_axis_label(t(' '));


//label colors
$chart['#mixed_axis_label_styles'][] = array(0,'000000',10);
$chart['#mixed_axis_label_styles'][] = array(1,'000000',10);
$chart['#mixed_axis_label_styles'][] = array(2,'0000ff',15);
$chart['#mixed_axis_label_styles'][] = array(3,'00ff00',15);

Looks fixed to me. fora, re-open if needed.
