Re: [Matplotlib-users] Memory leaks in a web application

[Matplotlib-users] controlling tick label size
Trying to find a simple way to shrink the tick labels for this plot -
since I can have many tiny histograms, the labels need to be smaller,
but it isn't obvious to me how to simply shrink them.
code snippet...
num = len(datasets)
fig = plt.figure()
rows = np.int(np.sqrt(num))
cols = np.int(float(num)/float(rows)+.9)
for i in range(num):
ax = fig.add_subplot(rows, cols, i+1)
ax.hist(datasets[i][np.isfinite(datasets[i])], bins=60 )
ax.set_xlabel(labels[i], size = 9)
ax.set_ylabel('Counts', size = 9)
plt.show()

[Matplotlib-users] different Locator for opposite axes
Hi everyone, I am plotting a figure where I need two independent x axes and two independent y axes. I've tried to use both twinx and twiny at the same time, and this works to some extent, but it looks like it is plotting the labels for the bottom x axis and the right-hand y axis twice, which makes me think that I must be doing something wrong (the numbers appear more 'bold'). The code is below. Is there a better way to do this? In reality, I don't need a different scale for the opposite axes, but I want to specify different Locator functions, but I assume that creating a new axes instance as done below is the only way to do this? Thanks for any advice, Thomas ### fig = figure() ax = fig.add_subplot(111) ax2 = ax.twinx().twiny() for tick in ax.yaxis.get_major_ticks(): tick.label1On = True tick.label2On = False tick.tick1On = True tick.tick2On = False for tick in ax.xaxis.get_major_ticks(): tick.label1On = True tick.label2On = False tick.tick1On = True tick.tick2On = False for tick in ax2.yaxis.get_major_ticks(): tick.label1On = False tick.label2On = True tick.tick1On = False tick.tick2On = True for tick in ax2.xaxis.get_major_ticks(): tick.label1On = False tick.label2On = True tick.tick1On = False tick.tick2On = True ax.scatter([0.4],[0.6]) ax2.scatter([10.],[10.]) draw() ### -- Create and Deploy Rich Internet Apps outside the browser with Adobe(R)AIR(TM) software.

Did anyone have any insight on this? Alternatively, anyone know why there
has been little uptake on this question ...(apologies that it was
accidentally sent twice)?

I've been having a devil of a time getting my rcParams to update
mid-script. Perhaps this isn't possible, but if that's so, it's not
entirely clear. Even if it is so, this is seemingly a defect, because in an
interactive session one expects quite different behavior (and no amount of
iPython %reset-ing seems to be able to help).
Note that manually setting the font (or what have you) in *title* works
fine.
Here is some example code:
## BEGIN #
import matplotlib
from matplotlib import rc, rcParams, rcdefaults
from matplotlib.pyplot import plot, show, figure, title
print matplotlib.__version__
print matplotlib.get_configdir()
print
print rcParams['font.sans-serif']:, rcParams['font.sans-serif']
print 'family is:', rcParams['font.family']
print
figure(4)
title('This should be in a sans-serif font')
show()
rcParams['font.sans-serif'] = rcParams['font.monospace']
print rcParams['font.sans-serif']:, rcParams['font.sans-serif']
print 'family is:', rcParams['font.family']
print
figure(1)
title('This should be in a monospace font')
show()
rcParams['font.sans-serif'] = rcParams['font.serif']
print rcParams['font.sans-serif']:, rcParams['font.sans-serif']
print 'family is:', rcParams['font.family']
print
figure(2)

show()

print 'family is:', rcParams['font.family']
print

Re: [Matplotlib-users] different Locator for opposite axes
Since you call twinx then twiny, you're creating two additional axes, not one.
And I guess this is why labels are drawn twice. You may do
def twin(ax):
ax2 = ax.figure.add_axes(ax.get_position(True),
frameon=False)
ax2.yaxis.tick_right()
ax2.yaxis.set_label_position('right')
ax.yaxis.tick_left()
ax2.xaxis.tick_top()
ax2.xaxis.set_label_position('top')
ax.xaxis.tick_bottom()
return ax2
ax = gca()
ax2 = twin(ax)
ax.scatter([0.4],[0.6])
ax2.scatter([10.],[10.])
draw()
Note that you need to manually adjust the view limits of each axes. If
you use sharex or sharey parameters for the axes, you can share their
view limits (this is how axes is created when twinx and twiny is
called). But then you cannot have different tick locators.
In case you need an axes with a same viewlimit as the original one but
just want to place ticks at different position, you may check my
related post.
