Hi All


I have 1D line plot and I want to export the data of the plot on selected grid points, not the entire plot. Any Idea or suggestion would be of great help.


Regards,
A.

I believe the answer to your question is:

Right click in "Derived Values"
choose "Point Evaluation"
Select the points and the expression
Evaluate

Also you can do in Matlab with the command mpheval or mphinterp

Dear Felipe


Thank you for your suggestions. I tried using 'Derived value' and then "Point Evaluation". In this way, only some (restricted ) points are available to choose.

By now I solved the problem using the following procedures.

1st. click 'Export'
2nd choose 'data'
- choose 'Grids' from ' points to evaluate in ' option
-finally define the grid (The starting point,,,grid gap and final points)
