plot error with matplotlib 3.8.2

[leahwang1962]

Hello,
The Montelmirror.py inside the examples folder works fine with Matplotlib3.5.1, but the below error happens when I upgraded to Matplotlib 3.8.2. Same error with other scripts need plot.

Thanks.

Hi,
The current xrt version is compatible with this new behavior of matplotlib. Please update.

It is the current version I am using. I just downloaded the zip file from here this afternoon.

No, you are not. The line "del graph.lines[:]" seen in the traceback is now commented out.

Do in your python session:

import xrt
print(xrt.__file__, xrt.__version__)

You will probably see an unexpected location.

Thanks.
After reinstall, I got the latest version 1.6.0 and the plot part is fine.
However there is another issue when the plot screen rotated 45 degree, or for other random orientation(no error if no rotation). It works fine at 1.4.0 version. Can you let me how I should modify the code? Greatly appreciate.
my code is like this:
beamLine.fsmMontelImage3 =rsc.Screen(beamLine, 'FSM-Montel', (0, p[0] + q[0], 0), (0.70711, 0, 0.707107),(-0.70711, 0, 0.707107))

Hi,
I've fixed this issue. The error is created during formatting a warning output. And the warning is about your x and z local vectors being not strictly orthogonal to each other, cf 0.70711 and 0.707107.
You may download the GH version or just rectify the screen's x and z.

Great. Thanks a lot.
