Extracting data from Surface plot

sdgff — Tue, 10 Apr 2018 15:03:29 GMT

Dear All,

I have fitted my response with three variables and found out the expression that relates the response to three variables. Now, I plotted the surfaces by keeping one of the variable constant using Graph---> Surface plot. Is there a way to extract the fitted surface into an excel sheet (X, Y, Z data) so that I can plot it in any other software?

Thanks,

Suraj

I am not aware of this ability in Surface Plot, however, you can use Contour Plot, and it will output the values.

If you have a model, there are many ways to do this, including the Contour Profiler, as mentioned. You could also use the Prediction Profiler in a similar fashion. If you want control on the various points, create a new table with the grid you desire and copy the prediction formula into the new table.

However, I do want to know: what is missing from the JMP Surface Plot that you want to see?

Thank you for your suggestion.

I actually want to overlay different surface plots on to a single plot which I am not able to do in JMP and also add transparency to the surface. So, I want to extract the surface so that I can plot in other softwares.

Thanks,

Suraj

The script below is copied from the Scripting Index. Run the script and from the Prediction Profiler menu, select Reset Factor Grid. A dialog opens where you can set the low and high values and the number of points. When finished (OK), select Output Grid Table. I think this might give you what your want.

I am interested in what software (routine) you will be using to generate the surface overlay.

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Tiretread.jmp" );
obj = Profiler(
	Y(
		:Pred Formula ABRASION,
		:Pred Formula MODULUS,
		:Pred Formula ELONG,
		:Pred Formula HARDNESS
	),
	Desirability Functions( 1 )
);
obj << Surface Profiler( 1 );
