Hi Sir/Madam,
I have created a Mountain Series with gradient fill. below is part of my code:

-(SCIRenderableSeriesBase *)getTimeSharePlot:(SCIXyDataSeries*)xySeries{
    SCIFastMountainRenderableSeries * rSeries = [SCIFastMountainRenderableSeries new];
    rSeries.dataSeries = xySeries;
    rSeries.strokeStyle = [[SCISolidPenStyle alloc] initWithColor:[UIColor colorWithRed:0 green:0 blue:0 alpha:1] withThickness:1];
    rSeries.areaStyle = [[SCILinearGradientBrushStyle alloc] initWithColorStart:[UIColor colorWithRed:32/255.0 green:56/255.0 blue:124/255.0 alpha:1.0] finish:[UIColor whiteColor] direction:SCILinearGradientDirection_Vertical];

    return rSeries;
}

When i run the test, the chart is just filling with solid color
Would you please help?
BR,
Tommy

Hi Tommy,

Unfortunately iOS doesn’t support PerScreen texture mapping, but It might be added in future since other platforms support it.

For now, please try setting SCIFastMountainRenderableSeries.ZeroLineY to YAxis minimum so it fills it like “PerScreen”. Hope that helps.

Best Regards,
Nazar R.
