attn @zblz You have been poking at this recently, any insight? |
|
I was poking at the non-latex stuff, but took a look to the issue. In the first case it's just that @neuronphysics: The following minimal working example works fine, can you provide a similar one that shows the issue? |
|
@zblz Thanks! |
|
@zblz I suspect that it has something to do with the conflication of and using Because I even ran the code with the way you have pointed out and I still get error messages. |
|
Note that The following example with all these things baked in still works for me, so I'm not sure these are the culprits: |
|
Well, in the script I would get this error message and this warning at the beginning: |
|
Can you reproduce this in a clean enviroment?
import matplotlib
matplotlib.use('PS')
matplotlib.rcParams['text.usetex']=True
matplotlib.rcParams['text.latex.unicode']=True
import pylab as plt
plt.switch_backend('PS')
string = r'z=${value}^{upper}_{lower}$'.format(
value='{' + str(0.27) + '}',
upper='{+' + str(0.01) + '}',
lower='{-' + str(0.01) + '}')
print(string)
fig = plt.figure(figsize=(3,1))
fig.text(0.1,0.5,string,size=24,va='center')
from matplotlib.backends.backend_pdf import PdfPages
pp = PdfPages('issue5076.pdf')
pp.savefig(fig)
pp.close()as @zblz posted above |

@tacaswell I can produce it! |
|
meaning the above works or the above generates an exception? |
|
The point is that I don't have a root permission and the latex library is not installed on my machine and I use a share library. I am getting this error: which I guess it means they are not installed or updated or not compatible. Do you think it might be a reason? |
|
That does not look like a complete error message and it is still not clear to me you ran to generate that error. |
|
The first error message shows the LaTeX packages ucs and inputenc being included: This originates from the usual matplotlib LaTeX unicode preamble. The problem in that case is that Nothing in matplotlib loads |
|
I tried running the script that @tacaswell wrote on a clean enviroment and I get this error:
|
|
I did a line by line check and the problem arises when we create the pdf, i.e. the line
is run, the rest of the script runs perfectly fine. |
|
The relevant error message in that output is: sh: latex: command not found For some reason, the “latex” binary is not found by the shell. Perhaps it is installed in an unusual directory and some profile files need updating. |
|
Reinstalled MacTeX and it works now, thanks! |
|
Sounds like this can be closed now, so I will do so. |
I have been trying to generate
Latexstyle plots for publication bywhere I want to plot different figures in multiple pages with this function:
But when I ran my script I've got the following errors:
even after I changed the text to
text = r"z=${value}^{upper}_{lower}$".format(
value=value, upper=upper, lower=lower)
I've got the following error:
How can I make this all work or avoid this error?
The text was updated successfully, but these errors were encountered:
