question about the diagonal line of RP plots

[Karl]

My recurrence plots all have a diagonal from the top left to bottom right. This is contrary to the examples provided in the documentation which run from bottom left to top right. Am I doing something wrong or does this depend on the data?

[Johann Faouzi]

It's just a visualisation issue, whether the origin is at the upper left (your case) or at the lower left (like in this example). You can change this setting using the origin parameter in matplotlib.pyplot.imshow().

thanks much!
