[Matplotlib-users] No autoscaled and correctly tickered logarithmic y-axis after zoom

[Thore O. <tho...@is...>]

Dear Matplotlib-Users.

After changing the scaling from the y-axis from default to semilogy the 
tickers were not updated anymore automatically when a zoom is applied.

Even after deep searches within the ticker API as well as the mail 
archive list I could not find an appropriate solution for this.

In the original artist/image (sorry for confused usage of this termini, 
I am pretty new to matplotlib): the scale has a default log10-base with 
major tickers including labels and minor tickers without (guess this is 
the default ticker formatting).

I was messing around a lot with autoscale(enable=True,axis='both') and 
set_autoscale_on(True) and relim(). But actually the sovereign handling 
ot this API is still missing for me and I was not able to solve the problem.

Thanks in advance for your help.

Kindly regards,
Thore Oltersdorf

Thore,

I cannot reproduce your problem as I understand it.  Could you please attach
a  copy of the image that shows the incorrect labeling?

Dear Benjamin.

Attached you find the same graph as for the other problem regarding the 
inline annotations. But now zoomed once to reproduce the correctly 
scaled x-axis but not autoscaled y-axis.

Kindly regards,
Thore

Thore,

I do not see a problem with the attached graph.  The graph looks correct to
me.  How is it different from what you expected to see?

Dear Benjamin.

Okay. Now I attached almost the same zoomed region but zoomed twice to a 
very tiny area thus you can see that even the minor tickers have 
vanished on the y-axis.

My question: how do I need to set the y-axis minor (probably major 
tickers, too) to see anything from the grid as well as the tickers itself.

Kindly regards,
Thore
