  Lines only contour plot
Posted by Adil on Sep-07-2022 06:25
Hi Peter,

Is it possible for a contour plot to have only lines without color floods between contour lines?
If yes, how to do that.

Hi Adil,

Yes, the fill colors are configuration. In particular, you can configure them to be transparent.

int noFillGradient[] = { Chart::Transparent, Chart::Transparent };
myContourLayer->colorAxis()->setColorGradient(false, IntArray(noFillGradient, 2));

There is also a contour chart example with no filling but with colored contour lines.

Best Regards
