    <p>You do not need to <code>plt.show()</code> if it is an animated (interactive) plot. You also want interactive set to True, not False which is the same as calling <code>ion()</code> in your 2d example. Also, you need to <code>remove()</code> the surface plots from previous frames if you do not want to see them all.</p> <p>Otherwise you were pretty close.</p> <p>This works for me:</p> <pre><code>import numpy as np import matplotlib.pyplot as plt from mpl_toolkits.mplot3d import Axes3D from matplotlib import cm from matplotlib.ticker import LinearLocator, FixedLocator, FormatStrFormatter import matplotlib, time class plot3dClass( object ): def __init__( self, systemSideLength, lowerCutoffLength ): self.systemSideLength = systemSideLength self.lowerCutoffLength = lowerCutoffLength self.fig = plt.figure() self.ax = self.fig.add_subplot( 111, projection='3d' ) self.ax.set_zlim3d( -10e-9, 10e9 ) rng = np.arange( 0, self.systemSideLength, self.lowerCutoffLength ) self.X, self.Y = np.meshgrid(rng,rng) self.ax.w_zaxis.set_major_locator( LinearLocator( 10 ) ) self.ax.w_zaxis.set_major_formatter( FormatStrFormatter( '%.03f' ) ) heightR = np.zeros( self.X.shape ) self.surf = self.ax.plot_surface( self.X, self.Y, heightR, rstride=1, cstride=1, cmap=cm.jet, linewidth=0, antialiased=False ) # plt.draw() maybe you want to see this frame? def drawNow( self, heightR ): self.surf.remove() self.surf = self.ax.plot_surface( self.X, self.Y, heightR, rstride=1, cstride=1, cmap=cm.jet, linewidth=0, antialiased=False ) plt.draw() # redraw the canvas time.sleep(1) matplotlib.interactive(True) p = plot3dClass(5,1) for i in range(2): p.drawNow(np.random.random(p.X.shape)) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
