There seems to be a problem when we add a series with a non-categorical x axis and one with a categorical x-axis to one chart. If we draw the series separately to a chart, they are displayed normally (see attachment; 2 charts on top), however if we want both series on the same chart, the chart acts very strange (see attachment; the bottom chart). The points on the categorical axis are not drawn on the label on the x-axis The points on the non-categorical axis are not drawn according their x value. Should we enable some options?

Thanks for the reply. I cannot find the Surface member in the Gallery enumeration. Are you refering to another version than 8.0.3422.28509 ? Also the ChartFX.WPF.XYZ assembly is not included in my trail version of ChartFX for WPF (8.0.3422.28509). Ben

I'm still trying to create a surface-kind chart with chart fx. Is it currently possible to create one? If not, is it on the roadmap to make it possible?

We are currently evaluating ChartFX for WPF. I was wondering how you have to create the first example that is demonstrated in the samples. (The surface chart - see attachment)
