Draw a custom Symbol/Primitive in a 3D chart

David posted over 16 years ago

As the title says, is it possible to draw a custom symbol (using say, the FillSceneGraph event) inside a 3D chart?

Right now I'm "overriding" 2D points in a scatter chart using this technique, but can't seem to find the way to add custom elements to a 3D chart.

Thanks, -David

There is not standard way to do this. You can’t change the color of the spheres and you can’t add new spheres in the 3D chart. You can add manually only 2D primitives to the chart.

What I'm trying to achieve is to color each data point based on a formula. I accomplished that in the ScatterChart by painting on top of the original data point, another symbol with the desired color.
My question is, is it possible to do the same thing in a 3D chart? That is, I can add more spheres manually to a Point3DChart for example.

Actually, you can add custom primitives to the 3D charts, but only 2D. I’m not sure what you want to do, but there is not standard way to put some symbol let says “in the middle of x-axis”. For creating our chart we are using GDI+ that doesn’t have built-in way to make 3D graphics. For our 3D charts we have implemented an engine for projection 3D elements to the 2D plane.
