By using the main menu option File/ASCII/CSV files/Export 3D-graphics, you can export all values from the visible part of the 3D graphic in one text file. There are 3 options: 


  1. Export in a file with X,Y,Z triples in 3 columns (tab delimited)
  2. Export a matrix where the first row contains X values, first column Y values and the rest of the file are Z values (tab delimited)
  3. Inverted variant of the second matrix format (with switched rows and columns).


All of these file types can be loaded by, for example, MS Excel for further analysis.
