Hi Jae-Joon and others,
i switched to using splines, but i still cannot see how to adjust the
space between the axis labels and the ticks of the axes. right now the
labels are too far away.
here is my code:
fig = plt.figure()
x = np.linspace(0,2*np.pi,100)
y = 2*np.sin(x)
ax = fig.add_subplot(2,2,1)
ax.plot(x,y)
show_spines(ax,['left', 'bottom'])
plt.xlabel('xlabel')
plt.ylabel('ylabel')
ax = fig.add_subplot(2,2,2)
ax.plot(x,y)
show_spines(ax,['left', 'bottom'])
plt.xlabel('xlabel')
plt.ylabel('ylabel')
ax = fig.add_subplot(2,2,3)
ax.plot(x,y)
show_spines(ax,['left','bottom'])
plt.xlabel('xlabel')
plt.ylabel('ylabel')
ax = fig.add_subplot(2,2,4)
ax.plot(x,y)
show_spines(ax,['left', 'bottom'])
plt.xlabel('xlabel')
plt.ylabel('ylabel')
plt.savefig('test.pdf')
i don't see how i could switch to plt.text or plt.annotate here. the
xlabel and ylabel functions automatically plot the label of an axis in
the center, which is exactly what i need. computing where the
coordinates where a label should be plotted with plt.text so that the
label appears in the center seems very messy and difficult, since it
requires knowing how much space the label will take (and that depends
on the font size etc.)
is there an existing parameter that just controls the distance between
the xticks and the label? it seems like there must be.. i just want to
bring them closer together.
thank you.
