subplots ( 2, 2, sharex = True, sharey = True ) # Creates figure number 10 with a single subplot # and clears it if it already exists. You can see all the available methods for an axes instance in the api docs, here. Likewise, to set a title, you need ax.settitle. (Compare these to plt.xlabel, etc., for the state-machine interface). subplots ( 2, 2, sharex = 'all', sharey = 'all' ) # Note that this is the same as plt. When using the matplotlib object-oriented interface, the correct commands to use are ax.setxlabel and ax.setylabel. subplots ( 2, 2, sharey = 'row' ) # Share both X and Y axes with all subplots plt. subplots ( 2, 2, sharex = 'col' ) # Share a Y axis with each row of subplots plt. scatter ( x, y ) # Share a X axis with each column of subplots plt. subplots ( 2, 2, subplot_kw = dict ( polar = True )) axes. scatter ( x, y ) # Creates four polar axes, and accesses them through the returned array fig, axes = plt. set_title ( 'Simple plot' ) # Creates two subplots and unpacks the output array immediately f, ( ax1, ax2 ) = plt. sin ( x ** 2 ) # Creates just a figure and only one subplot fig, ax = plt. Theĭimensions of the resulting array can be controlled with the squeeze **fig_kwĪll additional keyword arguments are passed to theįig : Figure ax : axes.Axes object or array of Axes objects.Īx can be either a single Axes object or anĪrray of Axes objects if more than one subplot was created. () method is also used to set the main title for all subplots in a figure. figure.suptitle() to Add Main Title for All the Subplots. subplot_kw : dict, optionalĭict with keywords passed to the GridSpecĬonstructor used to create the grid the subplots are placed on. In this case, the fontsize20 is set to make the main title distinguishable from the titles of each subplot. I have a dataset of images, each record contains 2 images, and if they are of the same class or not (built from Fashion MNIST dataset). Num : integer or string, optional, default: NoneĪ pyplot.figure keyword that sets the figure number or label. set a title for multiple subplots in matplotlib. If False, no squeezing at all is done: the returned Axes object isĪlways a 2D array containing Axes instances, even if it ends up for NxM, subplots with N>1 and M>1 are returned as a 2D array.for Nx1 or 1xM subplots, the returned object is a 1D numpy.Resulting single Axes object is returned as a scalar. if only one subplot is constructed (nrows=ncols=1), the.Sharey_ax = _get_share_ax(sharex, axarr, row, col)Īx= fig. Sharex_ax = _get_share_ax(sharex, axarr, row, col) If included, there must be one title for each row.ĭict with kewords passed to the `~_title` function.Ī common use is row_title_kw=')įig, big_axes = plt.subplots(nrows, 1, **fig_kw)įor (row, big_ax) in enumerate(big_axes):īig_ax.set_title(str(row_titles), **row_title_kw)īig_ax.tick_params(labelcolor=(1.,1.,1., 0.0), top='off', bottom='off', left='off', right='off')Īxarr = np.empty((nrows, ncols), dtype='O') Number of rows/columns of the subplot grid Here is an example of adding subplot titles to. To set the titles for subplots, however, you have to use the respective subplots axes objects settitle(). The subplottitles argument to makesubplots can be used to position text annotations as titles for each subplot. Sns.distplot(row_to_fn(size=200), ax=ax)ĭef _get_share_ax(share_var, axarr, row, col):ĭef subplots_with_row_titles(nrows, ncols, row_titles=None, row_title_kw=None, sharex=False, sharey=False, subplot_kw=None, grid_spec_kw=None, **fig_kw):Ĭreates a figure and array of axes with a title for each row. pyplot objects title() method to set its title. Row_to_fn = įig, axarr = subplots_with_row_titles(rows, cols, figsize=(cols*8, rows*6), The result looks like this:Įxample usage: import matplotlib.pyplot as plt It returns the same figure and axis array that subplots does with the row titles already included. The code is a riff on () with an additional argument for row titles. Sharing it here in case it saves others time. at 14:39 Add a comment 2 Answers Sorted by: 15 I could imagine creating an empty row of subplots at the top, with each of the subplots having its own title would act as a column title. I’ve had to google for this enough times now to know I should just write a function.
