Hello,
in this chart image how can I set a different color for each datalabel (for example 30 in red, 40 in green, 50 in blue, ...)?
I am using the php version.
Thank you

Hi Jim,
You may use Layer.addCustomDataLabel. For example:
$layer = $c->addLineLayer2();
$layer->addDataSet($myData, 0x0000aa)->setDataSymbol(CircleSymbol, 15, 0x0000aa,
0x0000aa);
for ($i = 0; $i < count($myData); ++$i) {
$color = ...... obtain the color of the data point ....;
$layer->addCustomDataLabel(0, $i, "{value}", "arialbd.ttf", "10", $color);
}
Hope this can help.
Regards
