.NET Math with Microsoft Chart Controls, Revisited

Posted on by Ken Baldwin
Easy Math Charting In an earlier post, we described how NMath types can be plotted using the Microsoft Chart Controls for .NET, but programmatically constructing Chart objects with data series bound to NMath objects. The latest release of the NMath libraries makes this process much simpler by providing adapter classes which easily construct basic math charts for you from NMath types: NMath 5....

Using NMath Charts with .NET 4.0

Posted on by Ken Baldwin
The NMath Chart DLLs (NMathChartMicrosoft.dll and NMathStatsChartMicrosoft.dll) are built against the .NET 3.5 version of the Microsoft Chart Controls for .NET (System.Windows.Forms.DataVisualization). The .NET runtime will not automatically replace this reference with the version of the Microsoft Chart DLL built into the .NET 4.0 Framework, unless you explicitly tell it to do so by adding the fol...

Fitting Geometric Primitives to Points Using Nonlinear Least Squares

Posted on by Ken Baldwin
We were recently contacted by a customer looking for help on how to use NMath to fit geometric primitives to clouds of 2D points. The solution is to cast the problem as a minimization. In the space of the parameters which define the geometric object, minimize the residuals with respect to the 2D points. NMath provides .NET classes for solving nonlinear least squares problems such as this, using th...

Using NMath with Microsoft Chart Controls for .NET

Posted on by Ken Baldwin
In 2007, Microsoft acquired the Dundas chart components, in order to deliver data visualization directly within Microsoft products. In October 2008, they released the Microsoft Chart Controls for .NET, which includes the Dundas ASP.NET and Windows Forms Chart controls. The Chart controls are available as a separate download for .NET 3.5. Beginning in .NET 4.0, the Chart controls are part of the .N...
