thanks to all for the replies. i am still having an issue with the log
scale of these plots. i am trying to hide the top and right axes of
the plot, since these should not be there when plotting a histogram or
a line plot. i use the following code:
import matplotlib
matplotlib.use('PDF')
import matplotlib.pyplot as plt
from matplotlib import rc
rc('font',**{'family':'sans-serif','sans-serif':['Helvetica']})
plt.rcParams['ps.useafm'] = True
rc('font',**{'family':'sans-serif','sans-serif':['Helvetica']})
plt.rcParams['pdf.fonttype'] = 42
plt.rcParams['font.size'] = 10
from mpl_toolkits.axes_grid.axislines import SubplotZero
fig = plt.figure(figsize=(5, 5), dpi=300)
ax = SubplotZero(fig, 1, 1, 1)
ax = fig.add_subplot(ax)
x = range(1, 11)
y = [5000, 900, 600, 500, 200, 110, 50, 20, 10, 5]
plt.plot(x, y, linewidth=1.5, c='k')
ax = plt.gca()
ax.set_yscale('log')
ax.axis["xzero"].set_visible(True)
# make other axis (bottom, top, right) invisible.
invisible = ["bottom", "top", "right"]
for n in invisible:
ax.axis[n].set_visible(False)
plt.savefig('test_logscale.pdf')
if i do this, the bottom x-axis labels disappear.
this only happens with SubplotZero -- which is needed to make the
irrelevant axes invisible, I think -- then the labels of the x-axis
disappear.
any idea how this can be fixed? i want those axes removed but i still
want the labels/ticks of the bottom x-axis to show.
thanks.
