Hi Lionel
Sorry ... slip of the key. I meant inexpensive not expensive. The 3D graphs
are quite impressive. You can even put multiple 3D graphs in a graph.
I don't know if these charts were produced on MathCAD but check out the 3
axis contour graphs on page 44 to 46 to see charts that are very effective
in trade analysis.
