Need inexpensive charting program

03/27/2009 11:03 PM

I have data sets of about 400 points each that have values of x,y,and z. I need a charting program that can create a 3 dimensional scatter plot of these points. I would like to be able to view the plot from different angles.

If you trust that there is no virus (I have no idea - I just now found this with a search), maybe this free macro for Excel would work:

Excell is only 2 dimensional

Check out Scilab- it is open source, similar to Matlab. Also, NIST DataPlot may be able to give you what you are looking for. Both are open source and gratis.

Thanks for the suggestions. After checking all of them plus a few others, I tested http://www.doka.ch/Excel3Dscatterplot.htm. It appears to do what I want. A more complete explanation is available at http://en.wikipedia.org/wiki/3D_projection. Even though Excel is only a 2D program, you can write macros that will yield 3D results. I'm also told that Macintosh comes with a piece of software called Grapher that will also work. Thanks again.
