Greek letter display error [1.5.1]

[HuiDong]

To help us understand and resolve your issue please check that you have provided
the information below.

• matplotlib version:1.5.1
  linux: ubuntu 16.04
  python: 2.7
• Installed from ubuntu source: sudo apt-get install ...

The wrong output figure is attached, along with a correct one obtained from matplotlib 1.4.2.

One interesting thing:
if I choose text.usetex: True, the formula is then correct, however, other font will be messed up, by which, I mean not Times New Roma.

Try removing everything in ~/.cache/matplotlib.

This is not the first time we have seen this, but is seems to be transient(ish)

Can you give us a MWE?

Thanks for prompt reply.

Actually, I have tried clean cache for matplotlib before. Nothing changes.

Please let me know the update. A MWE is attached below,

Thanks,
Hui

#==========================================
from numpy import *

After correcting syntax errors in your example it works as expected for me.

from numpy import *
from pylab import *

#==========================================
#matplotlib.rcParams['text.usetex'] = True

x=arange(0,6.28,0.1)
y=sin(x)

plot(x,y,'bo--')
xlabel(r"$J/\omega_0$")
ylabel(r"$1-\left\langle"
r"\psi_{S}\right|\rho_{\mathrm{steady}}"
r"\left|\psi_{S}\right\rangle-\rho_{00}$")
title("test title here")
savefig('./other.pdf')

show()

It works fine for me as well, both in 1.5.2 and master.

[HuiDong]

Thanks for checking. It is still not correct on my end.

Installed the master version from source code. The funny characters disappeared. It may related to version 1.5.1, which is from package for ubuntu.

And also, Installed from source code 1.5.1. No problem at all

This appears to be working for us and the original reporter, so I'm going to close this issue.
