I'm trying to put a large amount of data (3 pieces of information from each of 3 attempts) into one chart for comparison. The numbers vary widely, from .5 to multiple tens of thousands, because I'm working with different units. I thought I'd be able to display all the data having force, which is in the tens of thousands, on one axis, while velocity and distance (0 to a few dozen) would be on the secondary axis. Good in theory, but the data I put on the secondary axis filled under the line, so instead of an unobtrusive line, I now have giant blobs of color. Not at all useful when I have so many data points I want to put in. Any suggestions on getting rid of the fill (from what I've seen, this is a function of adding something to the secondary axis, which seems.....odd), or a better way to show the data? Help would be appreciated.
