Anyone know of a good free (or cheap) function plotter? I need to do some nice 3D Gaussian curves for my next tutorial. thanks

Maybe GNUPlot will help? I''ve only used it for 2D but the FAQ claims it supports ''plotting of three-dimensional data points and surfaces in many different styles (contour plot, mesh)''.

Grab yourself a demo version of Matlab from www.mathworks.com

Alternatively, write one a graphical output yourself... won''t take more than a few days of learning/coding!

As a final idea, if you only want a couple of functions and it''s a once off, send me the data and I''ll send you back the plots.

Cheers,

Thanks for the suggestions guys.

Timkin, I''ll take you up on your offer. I require two 3D plots of a Gaussian distribution. One with double the variance of the other.

Many thanks

I''m sorted now Timkin. Thanks for the offer anyway.

Sorry I didn''t get back to you in time... I got caught up yesterday afternoon doing other things and didn''t see your response requesting the plot.

May I ask what you wanted the plots for?

Just as a visualization for the neighbourhood function in a SOM (my next tutorial). I didn''t need anything accurate. In fact I ended up just drawing a 2D curve by hand and it does the job okay.
