This would not be too hard to code. I once built a program that let the user select a subset of data in a chart (by clicking on the first and last point of the subset), then output some statistical calculations in the sheet next to the chart. This was a great program that saved a lot of time in data analysis, and it was a lot of fun to build. M.G. -

We look at sections of a given curve by dragging the fill handles on the frame of the source data while looking at the embedded chart - a subject you (and almost no one else) has discussed elsewhere. Walkenbach's web site gives a macro for extracting information about the resulting data ranges. It would be very helpful if one could use this information, i.e. the x- and y- ranges. Being vba novices, however, we have not been able to automate the calculation of formulas like SLOPE and INTERCEPT. We have conjured up error messages unlike any I've ever seen before. This is a general problem with tutorials - they often don't cover subtelties in what otherwise seem like simple problems. I would very much appreciate your comments. Space does not allow for some of the many snafus I have run into. Many thanks, sincerely, mg, Bellport, NY This article (…Simple Physics Problem…) discusses a technique we use to analyze

I made the point that if you want to teach them to use a computer for solving scientific problems (as opposed to teaching programming), then a spreadsheet is a great place to start. I think your post is an excellent example of what I had in mind. I hope you get a good mark :)
