Free ( or a tleast cheap ) 3D surface plot for Windows ( possiblyCAD related )

Discussion in 'Computer Support' started by Richard Owlett, May 22, 2004.

  1. My data to plot inherently comes in values equally spaced on an x,y
    grid. The z values will values will have a WIDE dynamic range. I am
    looking at experimental data, not analytic functions.

    My input arrays will be from 10x1000 to 500x15000, or any permutation
    in between.

    I've tried Scilab ( in which I do my pre-processing ) and gnuplot.
    Both have two problems:
    1. they are not native Windows apps
    2. their primary orientation is towards analytic functions

    Is there something from the Computer Aided Drafting realm that I
    should investigate?

    Have you looked at Excel? No, seriously? I have used it to
    plot out height data for an entire OS grid square. You can
    easily make the z axis logarithmic or whatever.

  3. No I hadn't. And its been on my computer for YEARS ;)
    Not sure It will handle my largest arrays. But it may be a good start.
