Dim P As New NDataPoint(2.54)

b1.AddDataPoint(P)

the

b1.UseXValues = True

is causing problems..

That's becuase you don't provide an X value to the data point and the control automatically assigns 0 to the first one, 1 to the second etc. The data point p must be initialized with an x value - for example:

NDataPoint p = new NDataPoint(2.54, 2.0);
