Hello,

I want to Add a ring to my TChart Polar Bar with:
m_PolarBar.DrawRing( 1, m_PolarBar.EndZ ) and many other values.

I always get this exeption:

Object reference not set to an instance of an object.
at Steema.TeeChart.Drawing.Graphics3DGdiPlus.Ellipse(Int32 x1, Int32 y1, Int32 x2, Int32 y2)
at Steema.TeeChart.Drawing.Graphics3D.Ellipse(Int32 x1, Int32 y1, Int32 x2, Int32 y2, Int32 z)
at Steema.TeeChart.Styles.CustomPolar.DrawPolarCircle(Int32 HalfWidth, Int32 HalfHeight, Int32 Z)
at Steema.TeeChart.Styles.CustomPolar.DrawRing(Double value, Int32 z)

I am working with Version 2.0.2456.16162.

Is this bug fixed in a later version or do you have any other idears to draw a ring with a fix radius in the polarbar?

Thank you very much.
Cheers,
Daniela

Hi Daniela,

I've been able to reproduce the issue here in v2 and added it to our defect list to be fixed for future releases. This already works fine with TeeChart for .NET v3.

Hello,

is this bug fixed now?

Thanks,
Daniela

Hello Daniela,

No, this issue (TF02012231) hasn't been fixed in v2 yet. As I told you before, it already works fine in v3.
