Hi, I'm trying to draw a 3D graph of some points that I have generated in Excel, so I need to be able to import the data somehow into Maple then be able to plot it. I can produce the data in two formats, the easiest is a grid with x values along the side and y values along the top, then the z values fill in the grid. Alternatively I can create 3 columns, x, y, and z, so that the number of rows is the number of data points I have. I've been trying this for hours and haven't got very far. I've managed to get the data into Maple (version 10) using the Assistant - Import Data option on the Tools menu, and this produces some kind of matrix of my data. However it won't let me plot it!! Any help would be much appreciated! Thanks!
