Hi

I'm trying to shade a couple of areas of a plot I'm creating, I need

to shade the area above one line and the area below another.

According to the documentation it looks like I need to use the fill()

method but I can't get it to work, the code I use for creating the

plot is below:

# import required modules from matplotlib

import matplotlib

from matplotlib import figure

from matplotlib.backends.backend_agg import FigureCanvasAgg as FigureCanvas

# set matplotlib plot parameters

matplotlib.rcParams.update({

"font.size": 8.0,

"axes.titlesize": 10.0,

"axes.labelsize": 10.0,

"xtick.labelsize": 8.0,

"ytick.labelsize": 8.0,

"legend.fontsize": 8.0,

"figure.dpi": 300,

"savefig.dpi": 300,

"text.usetex": True

})

def parameter_space_plot(options):

# setup figure

fig = figure.Figure()

FigureCanvas(fig)

fig.set_size_inches(5, 5)

axes = fig.gca()

axes.grid(True)

axes.set_xlabel("Mass 1 / $M_\odot$")

axes.set_ylabel("Mass 2 / $M_\odot$")

# setup mass array

mass = numpy.arange(0, options.max_mass + 1, 1)

# plot min/max mass lines

axes.plot(mass, minimum_mass(options, mass), 'b-')

axes.plot(mass, maximum_mass(options, mass), 'b-')

# plot equal mass line

axes.plot(mass, mass, 'k--')

# set axes limits

axes.set_xlim([0, options.max_mass])

axes.set_ylim([0, options.max_mass])

# return plot

return fig

could anyone give me pointers as to how I could shade the region of

the plot about the maximum mass line and the area below the minimum

mass line?

Cheers
