This is a curve fitting sample application built with Curve Fit/X. We also include a sample application showing how to use most of the other functions available in Curve Fit/X. Both sample applications are included with full source code so you can see how easy it is to use the control.

The following example provided shows how to perform curve fitting. Just one line of code is all that is required to determine the coefficients for a smoothed cubic spline model and another line of code to implement the cubic spline model. 

Source Code Examples

Here we show the screen shots of sample applications built using the Curve Fit/X ActiveX component. The full source code is provided with Curve Fit/X for Visual Basic 6 and Visual Basic .Net. Note that the control itself is coded using C/C++.

Visual Basic 6

This application was built using Visual Basic 6. The processing for each method takes just one line of code to implement, the rest of the application is for the GUI and data display. You are free to use this source code as part of your application if you purchase Curve Fit/X.

Visual Basic .NET, Visual C#

This application, without the MSChart graphics control, is also implemented in VB6, VB.NET and VC#. It can also be implemented in VC++ 6, VC++ .NET, Delphi, Excel and MS Access.
