As seen in Chart examples ... Point ... Standard Point.

Select Cylinder - points are displayed as squares, legend shows a circle.

Hello Kevin,
This is not a bug. When you select the point cylinder shape style in 2D mode, the points look like squares because of the projection and because this is a point series (for example the cone shape will look like triangle). If you switch the chart in 3D mode you will be able to view the cylinder shape.

In 2D you can use the point sphere shape style.

Best Regards,

The bug is that the legend does not match the series shape!
