Hi,

I'm trying to figure out how I could use greek letters on axis labels,
without italic.
I have read a lot about alternatives, but I do need to use LaTeX to insert
a table inside the plot area.

Using mathtex it responds with normal font on greek letters.

What I`m doing wrong?

The following code plots my table, but greek letters are not in Arial.

import numpy as npimport matplotlib.pyplot as plt

t2 = np.arange(100)
fig  = plt.figure(figsize=(8,4))
ax = fig.add_subplot(111)

plt.rcParams.update({'font.family' : 'sans-serif',
                    'font.sans-serif' : 'Arial',
                    'font.style' : 'normal',
                    'xtick.labelsize' : 12,
                    'ytick.labelsize' : 12,
                    'mathtext.fontset' : 'stixsans',
                    'mathtext.default': 'regular',
                    'mathtext.tt' : 'Arial',
                     })
plt.subplots_adjust(left=0.12, right=0.95, top=0.95, bottom=0.1)


ax.set_xlim(0,100)
xvals = [0, 16.6, 33.33, 50, 66.66, 83.33, 100]
ax.set_xticks(xvals)
ax.set_xticklabels(['tick 0', 'tick 1', 'tick 2','tick 3', 'tick 4',
'tick 5', 'tick 6'])
ax.set_ylabel(r'$\mu$text $\eta$text $\cdot$ m$^{-2}$ s$^{-1}$')
ax.set_yticklabels(['0', '200', '400', '600', '800', '1000', '1200', '1400'])
ax.plot(t2, color='black')
ax.fill_between(np.arange(0, len(t2)),t2,0, color='black', alpha=0.8)

from matplotlib import rc
rc('font',**{'family':'sans-serif','sans-serif':['Arial']})
rc('text', usetex=True)
table = r'''\begin{tabular}{lccccccc}\hline&tick 0& tick 1 & tick 2 &
tick 3 & tick 4 & tick 5 & tick 6 \\\hline Vals & 32.00 & 3.28 & 5.80
& 5 & 8 & 45 & 7.3 \\\hline \end{tabular}'''
plt.text(20,80,table,size=10)

plt.show()


And an example using Mathtex, using regular fonts work out of the box, but
my table of course is included as plain text. I have to close my IPython
session and start it again to correct usage of plot parameters.

import numpy as npimport matplotlib.pyplot as plt

t2 = np.arange(100)
fig  = plt.figure(figsize=(8,4))
ax = fig.add_subplot(111)

plt.rcParams.update({'xtick.labelsize' : 12,
                    'ytick.labelsize' : 12,
                    'mathtext.fontset' : 'stixsans',
                    'mathtext.default': 'regular',
                    'mathtext.tt' : 'Arial',
                    })
plt.subplots_adjust(left=0.12, right=0.95, top=0.95, bottom=0.1)


ax.set_xlim(0,100)
xvals = [0, 16.6, 33.33, 50, 66.66, 83.33, 100]
ax.set_xticks(xvals)
ax.set_xticklabels(['tick 0', 'tick 1', 'tick 2','tick 3', 'tick 4',
'tick 5', 'tick 6'])
ax.set_ylabel(r'$\mu$text $\eta$text $\cdot$ m$^{-2}$ s$^{-1}$')
ax.set_yticklabels(['0', '200', '400', '600', '800', '1000', '1200', '1400'])
ax.plot(t2, color='black')
ax.fill_between(np.arange(0, len(t2)),t2,0, color='black', alpha=0.8)
#from matplotlib import
rc#rc('font',**{'family':'sans-serif','sans-serif':['Arial']})#rc('text',
usetex=True)
table = r'''\begin{tabular}{lccccccc}\hline&tick 0& tick 1 & tick 2 &
tick 3 & tick 4 & tick 5 & tick 6 \\\hline Vals & 32.00 & 3.28 & 5.80
& 5 & 8 & 45 & 7.3 \\\hline \end{tabular}'''
plt.text(20,80,table,size=10)

plt.show()
