CL_GUI_CHART_ENGINE set custom color for ChartLine

[bharden59]

Hello,

I'm looking for a way to customise the colours of the curves in a graphic.

To do this, I'm using the CL_GUI_CHART_ENGINE class with a ChartLine graph. I'm able to change the background and pass several globalsettings (I'm using GRAPHICS_GUI_CE_DEMO for inspiration) but I can't designate the default colours for the curves and I can't designate a colour for each of my curves.

Do you have a demo of a simplified code to help me?

Here is my current code for sending global settings:
