I have some geophysical data I want to chart. How can I generate contours, or
with the surface chart, how can I change the values for the coloured bands?
Thank you

EXCEL 2007

Try a Surface Chart.

To set one up:-

Hit the F1 Help Facility Key

In the Browse Excel Help section click on Charts

Next click on Chart types

Next click on Present your data in a surface chart

There are detailed instructions in here as to how to set one up.

If my comments have helped please hit Yes.

Don't get your hopes up, Excel's contour/surface charts are not very
sophisticated. The long and lat are categorical, not numeric, and the
algorithms that generate contours is rudimentary.

I've written about these charts in details:
