[Matplotlib-users] How to show matplotlib.image ?

[hjc520070 <jia...@16...>]

The following run well . But I just want to make the image, with the x and y
as axis and z as the image value ,show on the figure. In the pylab , we can
just give a command "imshow" ,But here , I fail to do it , I have try
ax.imshow() again and again ,but fail. Can sb give me some advice . Thank
you .

matplotlib.use("WXAgg") 
matplotlib.interactive(True) 
from matplotlib.backends.backend_wx import FigureCanvasWx 
from matplotlib.figure import Figure

class DynamicPlot(): 
    def __init__(self,Frame): 
        delta = 0.025 
        x = arange(-3.0, 3.0, delta) 
        y = arange(-2.0, 2.0, delta) 
        X, Y = meshgrid(x, y) 
        Z1 = bivariate_normal(X, Y, 1.0, 1.0, 0.0, 0.0) 
        Z2 = bivariate_normal(X, Y, 1.5, 0.5, 1, 1) 
        Z = 10.0 * (Z2 - Z1)       
        levels = arange(-1.2, 1.6, 0.2)       
        self.fig = Figure((8,8), 75) 
        self.canvas = FigureCanvasWx(Frame, -1, self.fig) 
        ax=self.fig.add_axes([0.1,0.1,0.8,0.8]) 
       
ax.contour(X,Y,Z,levels,origin='lower',linewidths=2,extent=(-3,3,-2,2)) 
app = wx.PySimpleApp() 
f=wx.Frame(None,size=(600,600)) 
f.Show(True) 
DynamicPlot(f) 
app.MainLoop()
