![]() The r preceding the title string is important - it signifies Text in the indicated locations (see Text in Matplotlib Plots for a Text can be used to add text in an arbitrary location, and Maintains internal references until close The figure appears on the screen, is not enough, because pyplot Released until the figure is explicitly closed withįigure, and/or using the window manager to kill the window in which More thing: the memory required for a figure is not completely If you are making lots of figures, you need to be aware of one Stateful wrapper around an object oriented API, which you can use It annoying that states (specifically the current image, figure and axes)Īre being maintained for you behind the scenes, don't despair: this is just a thin You can clear the current figure with clfĪnd the current axes with cla. title ( 'Easy as 1, 2, 3' ) # subplot 211 title subplot ( 211 ) # make subplot(211) in figure1 current plt. figure ( 1 ) # figure 1 current subplot(212) still current plt. plot () # creates a subplot() by default plt. subplot ( 212 ) # the second subplot in the first figure plt. subplot ( 211 ) # the first subplot in the first figure plt. Of course, each figure can contain as many axes and subplots You can create multiple figures by using multiple Placing axes manually and Multiple subplots for an Which allows you to specify the location as axes() where all values are in fractional (0 to 1)Ĭoordinates. If you want to place an axes manually, i.e., not on a You can create an arbitrary number of subplotsĪnd axes. The subplot call specifies numrows, numcols, plot_number where plot_number ranges from 1 to If none exists, just as an axes will be created (equivalent to an explicit The figure call here is optional because a figure will be created Setp function with a line or lines as argumentĭef f ( t ): return np.

There's discussion of this exact "bug" but a fix hasn't been released (as of 3.4.Lines = plt. ax.tick_params(axis='x', labelrotation=45) This option is simple, but AFAIK you can't set label horizontal align this way so another option might be better if your angle is not 90. plt.setp(ax.get_xticklabels(), rotation=45, ha='right') We still use pyplot (as plt) here but it's object-oriented because we're changing the property of a specific ax object. Similar to above, but loop through manually instead. # otherwise get_xticklabels() will return empty strings.Īx.set_xticklabels(ax.get_xticklabels(), rotation=45, ha='right')Īs above, in later versions of Matplotlib (3.5+), you can just use set_xticks alone: ax.set_xticks(ax.get_xticks(), ax.get_xticklabels(), rotation=45, ha='right') If you want to get the list of labels from the current plot: # Unfortunately you need to draw your figure first to assign the labels, In later versions of Matplotlib (3.5+), you can just use set_xticks alone: ax.set_xticks(, labels, rotation=45, ha='right') If you have the list of labels: labels = Īx.set_xticklabels(labels, rotation=45, ha='right') Object-Oriented / Dealing directly with ax Option 3a Option 2Īnother fast way (it's intended for date objects but seems to work on any label doubt this is recommended though): fig.autofmt_xdate(rotation=45) Easiest / Least Code Option 1 plt.xticks(rotation=45, ha='right')Īs mentioned previously, that may not be desirable if you'd rather take the Object Oriented approach. ![]() The OP asked for 90 degree rotation but I'll change to 45 degrees because when you use an angle that isn't zero or 90, you should change the horizontal alignment as well otherwise your labels will be off-center and a bit misleading (and I'm guessing many people who come here want to rotate axes to something other than 90). Many "correct" answers here but I'll add one more since I think some details are left out of several.
