Most of my issues have been answered through previous posts, but this is such
a specific problem, that I can't find the answer anywhere. I'm new to
matplotlib and therefore learning some of the basic things. My code is:
import matplotlib
import matplotlib.pyplot as plt
import matplotlib.pylab as plb
import matplotlib.font_manager as font_manager
import numpy as np
#Changing font at once
##font = {'family' : 'monospace',
## 'weight' : 'bold',
## 'size' : 18}
##matplotlib.rc('font', **font)
#Changing font individually
axis_font = {'fontname':'Arial', 'size':'18'}
font_path = 'C:\Windows\Fonts\Arial.ttf'
font_prop = font_manager.FontProperties(fname=font_path, size=20)
x = np.genfromtxt('test.txt',
skiprows=(3),usecols=(0),delimiter='',dtype=None)
y =
np.genfromtxt('test.txt',skiprows=(3),usecols=(1),delimiter='',dtype=None)
z =
np.genfromtxt('test.txt',skiprows=(3),usecols=(2),delimiter='',dtype=None)
fig, ax1 = plt.subplots()
ax1.errorbar(x, y, fmt = 'b-', linewidth=3.0, xerr = 0.0, yerr = z,
label="Linear")
ax1.set_xlabel('x-values', **axis_font)
ax1.set_ylabel('linear y-values', color='b', **axis_font)
for tl in ax1.get_yticklabels():
tl.set_color('b')
ax1.legend(loc=2, prop=font_prop)
for label in (ax1.get_xticklabels() + ax1.get_yticklabels()):
label.set_fontname('Arial')
label.set_fontsize(18)
ax2 = ax1.twinx()
y2 = np.exp(x)
ax2.errorbar(x, y2, fmt = 'r-', linewidth=3.0, xerr = 0.0, yerr = 1000*z,
label="Exponential")
ax2.set_ylabel('exponential y-values', color='r', **axis_font)
for tl in ax2.get_yticklabels():
tl.set_color('r')
ax2.legend(loc=1, prop=font_prop)
for label in ax2.get_yticklabels():
label.set_fontname('Arial')
label.set_fontsize(18)
#ax2.ticklabel_format(axis='y', style='sci', scilimits=(-2,2))
ax2.get_yaxis().get_major_formatter().set_powerlimits((2,2))
plb.savefig('test.png', bbox_inches='tight')
plt.show()
Which generates the plot shown below.
test.png <http://matplotlib.1069221.n5.nabble.com/file/n44376/test.png>
Now the question is about the line (two ways of doing the same):
#ax2.ticklabel_format(axis='y', style='sci', scilimits=(-2,2))
ax2.get_yaxis().get_major_formatter().set_powerlimits((2,2))
As can be seen from the plot, the 1e4 has both a different size and color
than the rest of the y-axis. I have tried so many methods, but it just
remains the same no matter. Can anyone help?
