Hi. Chart3D seems to be perfect to visualize a chart on one of my apps.

However I would need a way to read the point of a SurfacePlot of a Chart3D that was touched by the user? Something like a Chart .chartOverlay that has a ChartProxy that can convert screen coordinates of the chart in values, but in 3D (maybe using hit testing ).

Thanks and best regards.

I wonder if that's just possible.

In 3D, a point on screen could be the visualisation point of several points on the graph, from frontmost to the last in the back.

How would you discriminate between them ?
