[Matplotlib-users] Plotting boolean/logical data type

[Timo H. <tim...@gm...>]

Hello,

I'v made a small program which plots data from a CAN-bus log file. Some of
the data to plot is logical type on/off values (bit on or off). I have tried
to find a way to plot this kind of data with no success.

Basically what I want to do is to draw a horizontal line with relative y
co-ordinates and absolute xmin and xmax co-ordinate. Then I could draw a
line when a bit is high and have it always in plot area even when zooming
etc. Like axhline(...) but with relative y and absolute x
co-ordinates. Another way to do this could be using subplots, but I can't
figure out how to use same x-scale on the both plots.

Any suggestions?

Best Regards
Timo
