Greetings, I would like to plot to make a figure with 3 subplots of the form (221) to (223):  each subplot should show a bar3d plot of a matrix  each subplot should have it's own title The problems: a) I don't see (nor did i find something) how i can use subplots combined with bar3d (from the mpl_toolkits.mplot3d) package. b) I don't manage to give the 3d bar plot a title. In the attached code you will see that a title is set, but it does not show up in the figure Could someone please help me out with these problems? Thanks, q  The code for the basic plot of the matrix: from mpl_toolkits.mplot3d import Axes3D import matplotlib.pyplot as plt from matplotlib.ticker import FixedFormatter, LinearLocator, FixedLocator from numpy import * psi=1/sqrt(2)*array([1, 0, 0, 1]) rho=outer(psi,psi) fig = plt.figure() ax = Axes3D(fig) elements = (len(rho) * len(rho)) xpos, ypos = meshgrid(array(range(len(rho)))+0.25, array(range(len(rho)))+0.25) xpos = xpos.flatten() ypos = ypos.flatten() zpos = zeros(elements) dx = 0.5 * ones_like(zpos) dy = dx.copy() dz = absolute(rho.flatten()) ax.set_title('absolute') ax.bar3d(xpos, ypos, zpos, dx, dy, dz, color='#F8F800') plt.show()

I'm not sure its possible right now to do subplots with 3D. As for the title, I cannot either put titles on any 3D graphs... 2009/9/28 <qubax@...> > Greetings, > > I would like to plot to make a figure with 3 subplots > of the form (221) to (223): >  each subplot should show a bar3d plot of a matrix >  each subplot should have it's own title > > The problems: > a) I don't see (nor did i find something) how i can > use subplots combined with bar3d (from the mpl_toolkits.mplot3d) > package. > > b) I don't manage to give the 3d bar plot a title.

Try below instead of Axes3D. Obviously, "131" is the geometry parameter for subplot command. You don't need to add "ax" to "fig" since Axes3D do that by itself. from matplotlib.axes import subplot_class_factory Subplot3D = subplot_class_factory(Axes3D) ax = Subplot3D(fig, 131) This will show you the title also. However, the 3d axes will occupy smaller area than the area of the subplot.

Thanks, that works like a charm. final bonus question: How can i individually set the point of view/zoom level for the different 3d subplots? Currently, when i rotate/zoom (with the mouse) in one subplot, the changes are applied on all 3d subplots.

Hmm, axes3d does not seem to support it currently. I hope Reinier or others confirm this. Anyhow, here is a quick workaround you may try. from matplotlib.axes import subplot_class_factory class MyAxes3D(Axes3D): def _button_press(self, event): if event.inaxes == self: Axes3D._button_press(self, event) Subplot3D = subplot_class_factory(MyAxes3D) This makes rotate/zoom is effective only in the axes where the initial buttonpress event occurred. While I think it is reasonable to have Subplot3D and above fix in place, I'll defer this to Reinier or others who better know how Axes3D works.

Hi, I will have a look at mplot3d subplots next weekend and try to fix issues like this. I'll also add a working example.
