This example shows you how. Unless you are an application developer, I recommend using part of the pylab interface, particularly the figure, close, subplot, axes, and show commands. These hide a lot of complexity from you that you don't need to see in normal figure creation, like instantiating DPI instances, managing the bounding boxes of the figure elements, creating and reaslizing GUI windows and embedding figures in them. If you are an application developer and want to embed matplotlib in your application, follow the lead of examples/embedding_in_wx.py, examples/embedding_in_gtk.py or examples/embedding_in_tk.py. In this case you will want to control the creation of all your figures, embedding them in application windows, etc. If you are a web application developer, you may want to use the example in webapp_demo.py, which shows how to use the backend agg figure canvase directly, with none of the globals (current figure, current axes) that are present in the pylab interface. Note that there is no reason why the pylab interface won't work for web application developers, however. If you see an example in the examples dir written in pylab interface, and you want to emulate that using the true python method calls, there is an easy mapping. Many of those examples use 'set' to control figure properties. Here's how to map those commands onto instance methods The syntax of set is setp(object or sequence, somestring, attribute) if called with an object, set calls object.set_somestring(attribute) if called with a sequence, set does for object in sequence: object.set_somestring(attribute) So for your example, if a is your axes object, you can do a.set_xticklabels([]) a.set_yticklabels([]) a.set_xticks([]) a.set_yticks([]) """ from pylab import figure, show from numpy import arange, sin, pi t = arange(0.0, 1.0, 0.01) fig = figure(1) ax1 = fig.add_subplot(211) ax1.plot(t, sin(2*pi*t)) ax1.grid(True) ax1.set_ylim( (-2,2) ) ax1.set_ylabel('1 Hz') ax1.set_title('A sine wave or two') for label in ax1.get_xticklabels(): label.set_color('r') ax2 = fig.add_subplot(212) ax2.plot(t, sin(2*2*pi*t)) ax2.grid(True) ax2.set_ylim( (-2,2) ) l = ax2.set_xlabel('Hi mom') l.set_color('g') l.set_fontsize('large') show() Keywords: python, matplotlib, pylab, example, codex (see :ref:`how-to-search-examples`)
