Porting from 2019.1 to 2021.1

In This Topic

This topic describes the differences in the programming model between Nevron Chart for .NET 2019.1 and Nevron Chart for .NET 2021.1.

Triangulated Surface Series

Adding Data

The API to add data to the triangulated surface series has changed. The reason is that data is now packed in an interlaved array for better rendering performance. Previous code that adds data to the triangulated surface series like:

C#	Copy Code
triangulatedSurface.XValues.Add(X); triangulatedSurface.Values.Add(Y); triangulatedSurface.ZValues.Add(Z);

Copy Code

triangulatedSurface.XValues.Add(X);

triangulatedSurface.Values.Add(Y);

triangulatedSurface.ZValues.Add(Z);

Must be replaced with:

C#	Copy Code
surface.Data.AddValue(X, Y, Z);

Precise geometry setting

The propety UsePreciseGeometry has been removed and all code setting this property must be removed. The triangulated surface series now always uses computations that prevent floating point errors.
