set_useOffset(False) is not working #16232
Description
Hi,
I try to disable the offset computed to label the axes in the plot.
It looks like the global or local set of useOffset is just ignored.
Code for reproduction
import matplotlib
import matplotlib.pyplot as plt
from mpl_toolkits.axisartist.axislines import Subplot
# Disable it globally
matplotlib.rcParams["axes.formatter.useoffset"] = False
fig = plt.figure(figsize=(3, 3))
ax = Subplot(fig, 111)
fig.add_subplot(ax)
ax.axis["right"].set_visible(False)
ax.axis["top"].set_visible(False)
# Disable it locally
ax.get_yaxis().get_major_formatter().set_useOffset(False)
ax.set_ylim(10 ** 8, 10 ** 8 + 1)
print(ax.get_yaxis().get_major_formatter().useOffset)
# > False
plt.show()Actual outcome
Expected outcome
We should not see the 1e8 and the axis should be labelled without the remove of the offset.
Matplotlib version
- matplotlib 3.1.1

That's not the offset (which refers to an added offset, not a multiplicative factor). You can turn off the factor with set_scientific(False).

Thanks a lot.
It works, but it really sounds weird.
Cause I don't want to disable scientific notation for numbers in the axis, which could be used without problem. I don't want to have a splinting of the values in 2 which is exactly what is supposed to be done by useOffset.
Do you think there is a problem in the method naming? or the documentation?

The name is unlikely to change, but you are welcome to propose improvements to the docs.

The above example does not show offset, but the scientific notation:
with useOffset
without useOffset (falling back to scientific) in case of the given numbers
Only if you disable both offset and scientific notation will you get the complete numbers at the labels for the data provided in the example.
The offset and the scientific label are quite similar, but offsets have a +/- sign while the scientific scaling factor has not.

Then everything is working as expected.
But maybe an example with normal values on axis, and maybe your screenshot in the documentation could be really useful for other people.
Thanks a lot, i close this issue.
