How can I change figure size?

If I try to set the figure size before, it creates the plot on figure 2, if I set the figure size on figure 2 to creates the plot on figure 3, etc

If this doesn’t work:

plt.figure(num=1, figsize=(16, 10))

How can I change the figure size of the ggplot chart?

Right now you could do this (all code without testing it …):

from ggplot import * # sets the rcParam for figsize to a default
import matplotlib as mpl
mpl.rcParams["figure.figsize"] = "11, 8" # or  whatever you want
print( ggplot(...)  +...) 

Be aware that every usage of theme_gray() or theme_bw() will overwrite the mpl.rcparams again, so if you want to use these themes explicitly, you need to do it like this:

from ggplot  import *
theme_bw() # sets the default  to the bw settings
import matplotlib as mpl
mpl.rcParams["figure.figsize"] = "11, 8"
print( ggplot(...)  +...) # don't use any theme here!

Note that this hack is changed in the “Theme as contextmanager” PR #75, so if that’s merged you could do this:

from ggplot  import *
mpl.rcParams["figure.figsize"] = "11, 8"
print( ggplot(...)  + theme_matplotlib(rc={"figure.figsize": "11, 8"}, matplotlib_defaults=False)

There is also a ggsave(), but right now this doesn’t take a size parameter (I opened #96 for this)

Another solution, if you don’t want to alter matplotlib’s configuration:

from ggplot import *
from matplotlib import pyplot as plt

p = (ggplot(diamonds,
          aes(x='x', y='y', color='cut', fill='cut')) +
     geom_point() +
     facet_wrap(x='cut'))

# This command "renders" the figure and creates the attribute `fig` on the p object
p.make()

# Then you can alter its properties
p.fig.set_size_inches(15, 5, forward=True)
p.fig.set_dpi(100)
p.fig

# And display the final figure
plt.show()
