How to fix line colors in the Graph?

There are a lot of lines in the Graph. The color of the line changes when the Graph refresh. Is there a way to fix line colors?

Have you try to use the “Series Overrides” feature?

It’s a good idea. But I have hundreds of different curves, although I only show a few of them. It is unrealistic to set each curve, any other advice?

Make sure the series are returned sorted each time. Each datasource should handle this though. What datasource are you using?
