axes size

Jean-Baptiste> S?ll !

    Jean-Baptiste> I followed you advice to use directly axes to

    Jean-Baptiste> dpi=100)

    #ax = Subplot(fig, 211)
    ax = Plot.axes([0.1,0.3,0.8,0.7])
    #mrks = Subplot(fig, 212)
    mrks = Plot.axes([0.1,0.1,0.8,0.15], axisbg='c')

"Plot" is not from matplotlib. Please post a complete working
matplotlib example that replicates your problem and I'll take a look.

It looks like you are mixing the matlab interface with the OO
interface. axes is from matplotlib.matlab. If you want to use the OO
interface, use

    from matplotlib.figure import Figure
    from matplotlib.axes import Axes, Subplot
    # etc, etc

    ax = Axes(fig, [0.1, 0.3, 0.8, 0.7])

    mrks = Axes(fig, [0.1, 0.1, 0.8, 0.15], axisbg='c')
