I need to generate a 3-D graph of a matrix where values within the matrix depend on the top most row / and left most column. In other words, I need to extend the usual XY scatter plot to an XYZ version.
For example if the row are years ( 1,2,3,) and the columns are interest rates (0, 1% , 2%, 3%, 4%) and the data inside is accumulated value ( 1+i)^y, I would like to see a 3 x5 planar base with labels year and interest rate, with the values for each shown and there would a surface above it rising as high as the computed accumulation values in the cells. It should be easy, but I can't really get it to work.
Any help would be appreciated. Thanks!
