LaTeX legend with ParserError

[lcscosta]

Hi, thanks for your work.

I'm testing your library and find this error:

ValueError: 
 Normal: $\mu=0.07%$%, $\sigma=1.29%$%
                ^
ParseException: Expected end of text, found '$'  (at char 8), (line:1, col:9)

I discovered that this error are from riskfolio.jupyter_report(), searching a little bit more I get the lines of this error and I make a modification to be able to run this function.

https://github.com/dcajasn/Riskfolio-Lib/blob/06dfe24745dd8ab40665621e72cfeb40a80c2b2e/riskfolio/src/PlotFunctions.py#L1489-L1493

I rewrited this segment as:

label='Normal: $\mu=$'
        + '{0:.2%}'.format(mu)
        + ', $\sigma=$'
        + '{0:.2%}'.format(sigma),

Now the module are working as expected. If you need more information to try to reproduce the error, you can message me.

This is my pip freeze, if you want to test, I removed the riskfolio because I do modifications and installed from path:

Hi @lcscosta, there is no error. I've just tried it with several versions of matplotlib higher than 3.5 and it works well. I recommend you to use a scientific Python distribution like Anaconda or Winpython to avoid problems.

Hi, I am runnng Anaconda and have Matplotlib version 3.8.2 and also get the error.

ValueError: 
Normal: $\mu=0.09%$%, $\sigma=0.80%$%

ParseException: Expected end of text, found '$'  (at char 8), (line:1, col:9)

Hi @GrantWise,

Do you have installed Riskfolio-Lib=5.0.1 ?

Best, Dany
