Asserts in sample in Point2D::Draw #15

Closed PBfordev closed 2 years ago

PBfordev commented 2 years ago

When running a sample and trying to show some charts (e.g., Line Plot or Linear Regression Roadmap), an assert is shown: D:\dev\Desktop\Lib\Wisteria-Dataviz-GIT\src\base\shapes.cpp(209): assert "m_drawFunction" failed in Wisteria::GraphItems::Shape::Draw(): Shape failed to set drawing function!

Call stack

It seems that m_drawFunction is null because m_shape is Blank but as I am not familiar with code I do not know whether the problem is that the m_drawFunction is null when it should not be or whether the assert should take m_shape being Blank into account.

Windows 10 v19044.1889, wxWidgets GIT master built 64-bit Debug Static, both displays set at 125% DPI.

Sorry for flooding the repo with issues, I have not even really tried the library, as I always fail with some issue like this.

Corrected the assert for blank shapes, all samples are working again. Thanks!
