range doesn't work, or am I making a mistake?

[astronom-v-cube]

Greetings. I tried to use the range parameter according to the documentation:

A list where each element is either a length 2 tuple containing lower and upper bounds or a float in range (0., 1.) giving the fraction of samples to include in bounds, e.g., [(0.,10.), (1.,5), 0.999, etc.]. If a fraction, the bounds are chosen to be equal-tailed.

My array is called ranges and looks like this, for example: ranges = [(1000000, 1e+08), (3e+08, 7e+09), (0, 360), (0, 1000), (100000, 10000000)].
When I try to use a variable as a function corner.corner argument, I get an error:

Traceback (most recent call last):
  File "d:\Документы\solar_radio_diagnostics\using.py", line 66, in <module>

    a.sort(axis=axis, kind=kind, order=order)
numpy.AxisError: axis -1 is out of bounds for array of dimension 0

When substituting an array directly as an argument to a function call (range=[(1000000, 1e+08), (3e+08, 7e+09), (0, 360), (0, 1000), (100000, 10000000)]), I do not get an error, however, there is also no result.

My code, if necessary, you can see here

Please put together a minimal, reproducible example that demonstrates the problem. Thanks!

Yes, I should have done it right away, sorry. The problem is that I couldn't reproduce this bug right away. Now, by the method of many attempts, I was able to find a situation where it manifests itself.
The root of the problem is exactly how to call figure, as an argument or as a variable.

import numpy as np
import corner
import matplotlib.pyplot as plt

data = np.random.normal(1, 300, size=(3000000, 4))
ranges = [(0, 800), (0, 900), (0, 750), (0, 350)]

fig_no_bug = corner.corner(data, range = ranges) 
plt.show()

fig_bug = plt.figure()
corner.corner(data, range = ranges, fig = fig_bug) 
plt.show()

The first method of calling works, the range is respected:

The second method of calling does not work, the range is not respected:

Another problem seems to be the use of the float type in range (360. and 360). However, this is easily solved by switching to int.

Thanks for this example! I can reproduce the issue and I believe I know how to fix it. But...

Can you say more about what this issue is here? There shouldn't be any problems with using floats.

This issue has been closed because the primary issue with range not being respected when a blank figure is an argument has been fixed in #224. But please feel free to provide more info about the data type problem you found or open a new issues. Thanks!
