The move_colorbar command moves the colorbar to a new position. The default transform specifies that text is in data coords, alternatively, you can specify text in axis coords ((0, 0) is lower-left and (1, 1) is upper-right). If True, set the Axes aspect to "equal" so each cell will be square-shaped. close: Close a figure window. Matplotlib also able to create simple plots with just a few commands and along with limited 3D graphic support. You can vote up the examples you like or vote down the ones you don't like.
