findobj in pylab

Community matplotlib-users

Is there a way to find all the "axes" objects or "line" object handles in
pylab? In matlab I used to do something like
A = findobj(gcf)
Allaxes = findall(a,'Type','axes')
Set(allaxes,'Fontname','Arial')

Is there a way to do that in pylab/matplotlib?

Thanks,

j

Hello John,

I'm not sure there is a better way, but the following works for me:

···

--------------------------------------------------------------------------------------
from pylab import *

fig = figure()

# adding some subplots / axes instances
subplot(121)
x = linspace(-0.5, 1.5, 10)
plot(x, 0.5*x**2, 'ro', x, 0.33*x**3, 'bs')
for i in [2, 4]:
    subplot(2,2,i)

# get all axes of the figure 'fig' ...
allaxes = fig.get_axes()
# ... and reset their property x-limits
setp(allaxes, 'xlim', (-.5, 1.5))

ax = allaxes[0]
# get all lines of the axes 'ax' ...
lines = ax.get_lines() # == ax.lines
# ... and reset their markerfacecolor
setp(lines, 'mfc', 'g')

show()
