Hi
I display two data vectors : the first is in the subplot 2,1,1 and the second in the subplot 2,1,2. Each of the data vectors have an x vector of dates to display values on x axis.
The 2 data vectors are correlated in time and I want to show the correlation.
But the two data vectors are not aligned as I wanted them to be since the data vector of subplot 2,1,2 have less element than the other one.
I can’t use the same x vector for both curves since it would force me to add empty values in the second data vector. And I don’t want to do that since it would add useless points in my curve.
So I need to find a way to allow me to align both data vectors on the different subplots without adding point to the data vector with a smaller number of elements.
Thanks
Johan
Does this do what you want?
ax1 = subplot(211)
ax1.plot(x1, y1)
ax2 = subplot(212, sharex=ax1)
ax2.plot(x2, y2)
ditto for sharey if you want to share the same y axes...

This is exactly what I wanted.
Thanks a lot.
I just wanted to know wether it was possible to add a little margin for the y axes because I can’t see the highest point of the curve since it’s on the edge of the subplot.
Anyway, thanks a lot for the good work.

Yes, just set the xlim or ylim as desired
xlim(-5,5)
ylim(-6,10)
We should consider fix the autoscaling so that tthe default view lim
are always open intervals that contain the data.

This has been on my mental list for a long time. I will look into it.

Anyway guys, thanks a lot for the fast answer and all the good work you’re doing.
