( pyplot is just a convenience wrapper. subplots (2, 2) #create chart in each subplot sns. Then a space and plot 4 and 5 right next to each other. Subplot-adjust did not work for me, since the whole figure would just resize with the labels still out of bounds. For more advanced use cases you can use GridSpec for a more general subplot layout or Figure. subplots_adjust(left=0. subplot2grid. matplotlib. random (( 100 , 100 )), cmap = plt . I know how to set the relative size of subplots within a figure using gridspec or subplots_adjust, and I know how to set the size of a figure using figsize. A solution to this is putting the adjustment logic in a draw callback. In the edge case where Q1 == Q3, whis is automatically set to (0, 100) (cover the whole range of the data) if autorange is True. #. The examples below show how to use matplotlib. supxlabel and FigureBase. > If arg is an array, figaspect will determine the width and height for a figure that would fit array preserving aspect ratio. axes.

So potentially something is special about your case, concerning the matplotlib version in use or the environment where the code is run. But wspace command doesn't work and there is still a gap between plots like this quiestion (Matplotlib adjust image subplots hspace and wspace). This could be done as. First row contains the lower errors, the second row contains the upper errors. Each axes can have a title (or actually three - one each with loc "left", "center", and "right"), but is sometimes desirable to give a whole figure (or SubFigure) an overall title, using FigureBase. The available keys are: cell (tuple, default=(1,1)): (row, col) index of theSubplots, axes and figures. One thing you could change in your code very easily is the fontsize you are using for the titles.
