Re: [Matplotlib-users] How to control the y feedback value?
Sent from my iPhone On Sep 19, 2013, at 9:58, Sterling Separately, if your blue data are so quantized, you might use the blue data to choose a color for an axvspan (or axhspan, I forget which is which) to indicate how certain regions of time have different values of blue data. Then you would only need one set of axes, and your x,y labels would indicate what you want. Or perhaps colour the line segments based on the discrete value. Cheers.

Re: [Matplotlib-users] How to control the y feedback value?
I assume that you are using a twinx call to get the second y axis. I think that this question has come up before, and I think the solution was to switch which data are put on the second set of axes. (Of course to keep the same visual layout you would have to play with the y axis spine locations.) Good point. I just changed the command line options so the plot whose Y values are of interest are plotted on the right Y axis. Separately, if your blue data are so quantized, you might use the blue data to choose a color for an axvspan (or axhspan, I forget which is which) to indicate how certain regions of time have different values of blue data. Then you would only need one set of axes, and your x,y labels would indicate what you want. This also works, though I (and anyone looking at the graph) would have to remember the mapping between color and numeric value. If I was a synethete this might work, but I doubt most people would automatically recall the mapping. :-) Thx, Skip -- LIMITED TIME SALE - Full Year of Microsoft Training For Just $49.99! 1,500+ hours of tutorials including VisualStudio 2012, Windows 8, SharePoint 2013, SQL 2012, MVC 4, more.

I would add a figure or axes legend with proxy artists for the appropriate color mappings, or even just a bunch of text boxes with the text label colored appropriately.
