Matplotlib 2 inconsistent font

Question

I updated Anaconda Python to the latest version (4.3), where they upgraded Matplotlib to version 2.

The upgrade has made some major changes to the default style (see

If consistency is the only issue, you can use a "Roman" style using the "Times" font. It is not necessary to use Latex via usetex. Instead simply use the STIX fontset, the Times font and serif mathtext.

import scipy as sc
import matplotlib.style
import matplotlib.pyplot as plt

params = {'legend.fontsize': 18,
          'axes.labelsize': 18,
          'axes.titlesize': 18,
          'xtick.labelsize' :12,
          'ytick.labelsize': 12,
          'grid.color': 'k',
          'grid.linestyle': ':',
          'grid.linewidth': 0.5,
          'mathtext.fontset' : 'stix',
          'mathtext.rm'      : 'serif',
          'font.family'      : 'serif',
          'font.serif'       : "Times New Roman", # or "Times"          
         }
matplotlib.rcParams.update(params)

x = sc.linspace(0,100)
y = x**2
fig = plt.figure('Fig')
ax = fig.add_subplot(1, 1, 1)
lines = ax.semilogy(x, y)

ax.yaxis.set_minor_formatter(matplotlib.ticker.ScalarFormatter())
ax.tick_params(axis='y', pad=10)
ax.set_yticks([300], minor=True)
ax.yaxis.grid(True, which='minor')
ax.set_xlabel(r'$\mathrm{R_L}$')
ax.set_ylabel(r'$\sigma \int_l \; dx$')
plt.tight_layout()
plt.show()
