I have a large Excel worksheet (200 columns, 4,000 rows). Every column has a unique and carefully chosen title/label. I'm attempting to use it within Mathematica to create a large number of contour plots (1,000) -- using three columns at a time, for x, y, z. The import, I suppose, occurs. At least it appears to have. Here's the question: -- Is Mathematica using my column titles, so that I can refer to them in commands subsequent to import? -- If not, is there any format I can put my data into to begin with so that Mathematica will readily recognize my named columns? I certainly wanted to be getting on with the contour plots (SmoothDensityHistogram), but am having trouble getting my data into the required form. Any help appreciated.
