Hi all,
I’m relatively new to matplotlib and what I’ll ask to you seems to be simple but I just can’t figure out how to do this. I’d like to change the origin of my coordinate system to the upper left of my axis when I plot my figures. In matlab I use axis(‘ij’) but in matplotlib I couldn’t find something similar. How will I do this ?
Thank you for your help,
Jaonary
I am not 100% sure what you are asking and I don't have a matlab
install handy to test. If you want to plot a decreasing scale on the
y-axis, that is easy, just invert the min and max args to the ylim
ax.set_ylim(ymax, ymin)
If you want to do something more sophisticated, please describe in
detail and then I may have to tell you it is not currently supported

In fact, that’s what I wanted to do : put the origine of my axis on le upper left corner of my axis
with the values of y increase from top to bottom. And the tip you gave (set_ylim) do it kindly.
Thank you again for your help.
