Graphing a particular function...


Hi everyone
i am running ubuntu linux and i wish to know if is available a tool of this kind:
i have to make a grap of the variation of a quantity on a rectangolar surface...
in fact is sort of a radial graph, where all the same values are connected by ellipsys..
you can see an example here: http://www.fas.org/nuke/guide/usa/do...-9/figA-II.gif
Is there something available on linux?

You might be able to do something like that using jpgraph. From what I remember of the documentation it was capable of handling radial graphs.

If not, I would expect that the program R could do it as well.

actually is not a true grap because i am not graphing a continue function but only a set of values..
the prog should interpolate them and make those iso linees

Ah... then R will probably be a better choice as I believe it may have options for that. I don't really know, as I don't use the software normally.

You may also want to look into gnuplot & LaTeX's curve package. The LaTeX curve package can draw curves by means of second-degree Bezier splines where it is necessary to specify only the interpolation nodes. The macros determine the control nodes.
