I'm trying to plot some data but have some trouble. I have a list of x-y-z coordinate data. X-Y are irregular (not a grid).
What i do:
set dgrid3d //to interpolate the data
splot 'file' with pm3d
What i get:
- Nice 3d graph with the results I want: right side has higher z values than left one.Sorry i didn't find out how to upload pictures
The Problem:
Looking at the z-scale (which in my case goes from 26 to 44) I see there is a Problem: My data have z value going from 20 to 90.
My data set contains about 1000 points and i'm afraid, that not all of them are considered
I think this is due to the way dgrid3d works (is it trying to smoothen "rough" data and therefore i get wrong graph.
Important Informations:
My data seem ok and also correctly read, since the transition bwtween my right (high z-values) and left (low z-values) is exactly where it should.
I'm using Version 5.0 patchlevel 3 on a windows machine.
Thank you,
Célian.
