Hi Peter,
How can I set the continuous color gradient with a custom color scale that i assigned in C++.
For example, my colorScale is :
double colorScale[] = {0, 0x0066ff, 15, 0x66ffff, 20, 0x00ff00, 30, 0xff6600, 40};
but when i use setColorGradient, the color scale is change into default
sorry,my english is poor, thank you for your help. |

Hi Chen,
To set a color scale, the API should be ColorAxis.setColorScale. For a continuous gradient, the number of color stops must equal to the number of colors. See:
https://www.advsofteng.com/doc/cdcpp.htm#ColorAxis.setColorScale.htm
For your case, the code should be:
// 4 colors at 4 positions
double colorScale[] = {0, 0x0066ff, 15, 0x66ffff, 20, 0x00ff00, 30, 0xff6600};
myColorAxis->setColorScale(DoubleArray(colorScale, 8));
Hope this can help.
Regards
Peter Kwan |
