Notes. Figure subfigures#. pip install mpl-scatter-density Example code Sometimes it is desirable to have a figure with two different layouts in it. This example displays the difference between interpolation methods for imshow. The main difference with the previous plots is the configuration of the theta start and end limits, producing a sector instead of a full circle. plot (theta, r) ax. class matplotlib.ticker.StrMethodFormatter(fmt) Use a new-style format string (as used by str.format()) to format the tick. the Specifying Colors tutorial; the matplotlib.colors API; the Color Demo.

Valid keyword arguments are: So colorlist needs to be a list of floats rather than a list of tuples as you have it now. Below is a comparison of different methods.

If you want an image file as well as a user interface window, use pyplot.savefig before pyplot.show.At the end of (a blocking) show() the figure is closed and thus unregistered from pyplot. Colormap reference#. Calling pyplot.savefig afterwards would save a new and thus empty figure. This question is a bit tricky before Jan 2013 and matplotlib 1.3.1 (Aug 2013), which is the oldest stable version you can find on matpplotlib website. So colorlist needs to be a list of floats rather than a list of tuples as you have it now. Valid keyword arguments are: Circle (xy, radius = 5, ** kwargs) [source] #.

To start, Joe Kington's answer provides very good advice using a gui-neutral approach, and you should definitely take his advice (especially about Blitting) and put it into practice.
