ezrc

def ezrc(fontSize=22., lineWidth=2., labelSize=None, tickmajorsize=10,
         tickminorsize=5, figsize=(8, 6)):
    """
    Define params to make pretty fig for slides and papers
    """
    from pylab import rc, rcParams
    if labelSize is None:
        labelSize = fontSize + 5
    rc('figure', figsize=figsize)
    rc('lines', linewidth=lineWidth)
    rcParams['grid.linewidth'] = lineWidth
    rcParams['font.sans-serif'] = ['Helvetica']
    rcParams['font.serif'] = ['Helvetica']
    rcParams['font.family'] = ['Times New Roman']
    rc('font', size=fontSize, family='serif', weight='bold')
    rc('axes', linewidth=lineWidth, labelsize=labelSize)
    rc('legend', borderpad=0.1, markerscale=1., fancybox=False)
    rc('text', usetex=True)
    rc('image', aspect='auto')
    rc('ps', useafm=True, fonttype=3)
    rcParams['xtick.major.size'] = tickmajorsize
    rcParams['xtick.minor.size'] = tickminorsize
    rcParams['ytick.major.size'] = tickmajorsize
    rcParams['ytick.minor.size'] = tickminorsize
    rcParams['text.latex.preamble'] = ["\\usepackage{amsmath}"]

So I assume you would use it thusly:

x = np.arange(100.)/99.*4.*np.pi
y = np.sin(x)

ezrc()
fig = plt.plot(x,y)
plt.savefig('paper.pdf')
fig.close()

ezrc(fontSize=34, lineWidth=8)
fig = plt.plot(x,y)
plt.savefig('slide.pdf')

Is there a way to change the rcParams and then force figures to update? So then you could do:

x = np.arange(100.)/99.*4.*np.pi
y = np.sin(x)

fig = plt.plot(x,y)
ezrc()
plt.savefig('paper.pdf')
ezrc(fontSize=34, lineWidth=8)
plt.savefig('slide.pdf')
