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!
