Need help with Analysis.Math to find slope and intercept

[Paulie Walnuts]

Hi all!

I am trying to use NationalInstruments.Analysis.Math to calculate the slope and intercept of a scatter graph using VB. I'm using the CurveFit property but cannot find any resources regarding the applicable syntax. Any any help would be greatly appreciated.

Thanks in advance!

Hi,

In Measurement Studio 6 there was a straitforward solution to your problem.

Dim slope, intercept, mse, z As Object
Form1.Stat1.LinFit(xvalues, yvalues, z, slope, intercept, mse)

In the .NET versions it doesn't look so simple.

Try this instead

Hope this helps
