Generate Interpolation points

[#1]

If I measured some sites on several wafers. What are the options in Jmp to calculate interpolated values across all sites on the wafer?

To use Fit model (with By group) and save the fit model as an equation to the table is not accurate enough.

I was thinking about some spline fit, linear or gaussian interpolation.

Best: directly via JSL.

Alternatively, for a points plot, I can save the fit and the smoother formula.
Is it possible for a contour plot to save the "color" vs. x/y formula?

Does Interpolate have a group by option?
Group by - sooo useful!!! how about Interpolate?

I think you might be able to get what you want using the contour map.  You can input your raw XYZ data and then specify the number of contours and then finally output it into a grid of whatever precision you want.

Nice, thanks

I was so focused on GraphBuilder. Interesting that Contour Plot provides more options ...

• export interpolation grid
• Labelling of iso lines in contour plot generated via graph builder
