I'm sure some of you have spreadsheets that you use to graph your data logs. I'm having trouble getting Excel to graph things the way I want, and I'm sure someone else has gone through this before, so please post your spreadsheets.

What I'm looking for is to be able to graph all of the parameters on one graph with multiple axes, i.e. I want to be able to see rpm (0 to 8000) and manifold pressure (-30 to +15), etc. on one graph without the manifold pressure showing up as a relatively flat line at the very bottom.

 

I have just the instructions you need I put them together a while ago because someone asked me if I could graph them. The way I got around the problem you are having is divide the larger numbers by either 10 or 100 so they would all be close to the same values.

Normalize the numbers to the same scale. Click on sig "datalog" for a 2D graph with normalized data.
