Hi

We are displaying multiple series on chart and the series have custom axis. PFA herewith the snapshot of problem we are describing.
The problem is that when you scroll the data in one of the series, the series data gets drawn in the area of another series. Actually if series data goes out of series range it should not display anything.

Below is the sample code depicting the problem.

Hello VarUser,

I recommend that you take a look in the Demo project concretely in the All Features\Welcome !\Axes\Opaque zones where works with custom axes and doesn't allow that series are drawn in the area of another series.

I hope will helps.

Thanks,
