#SUBPLOT FIGSIZE PYTHON HOW TO#

Inner_ax_height = axis_height / figheight

V_margin = (figheight - (nrows * axis_height)) / figheight / nrows / 2 # spacing on each top and bottom of the figure H_margin = (figwidth - (ncols * axis_width)) / figwidth / ncols / 2 # spacing on each left and right side of the figure Within the grid defined by nrows, ncols, and figsize.Īllows you to share y and x axes, if desired. Spaces axes as far from each other and the figure edges as possible Sharex: bool=False, sharey: bool=False) -> Tuple:

The arguments include absolute height and width for the figure (see the matplotlib documentation for details) and absolute height and width for the axes, as requested in the original question. It centers the axes inside their grid areas, giving them as much space as possible between themselves and the edges of the figure, assuming you set figsize large enough. I created a function that creates axes with absolute sizes and acts in most ways like plt.subplots(.), for example by allowing shared y- or x-axes and returning the axes as a shaped numpy array. Plt.savefig(f'-subplots.pdf', bbox_inches='tight', pad_inches=0) To get started using Matplotlib in a Python program, either include the symbols from the pylab module (the easy way): In 2: from pylab import or import the matplotlib.pyplot module under the name plt (the tidy way): In 3: import matplotlib import matplotlib. Note that you could break this if you use savefig with a different explicit dpi value. The three integer parameters are: nrows, ncols, index. If I make the height of the resulting PDFs the same (and thus the axes), the font on 3-subplots.pdf is smaller than that of 2-subplots.pdf.įig, ax = plt.subplots(1, cols, sharey=True, subplot_kw=dict(box_aspect=1)) Figure size in pixel Similarly, one can use a conversion from pixels. We are now being explicit about the the default values that. In the example below the fonts are the same size but the subplots are not. I need each of the 5 subplots to be the exact same size with the exact same font sizes (axis labels, tick labels, etc) in the resulting PDFs. One has two subplots and one has three subplots (in both cases in 1 row). Use case: I am making two separate plots which will be saved as pdfs for an academic paper. For more advanced use cases you can use GridSpec for a more general subplot layout or Figure.addsubplot for adding subplots at arbitrary locations within the figure. My problem is setting the absolute size of the subplots. pyplot.subplots creates a figure and a grid of subplots with a single call, while providing reasonable control over how the individual plots are created.

#SUBPLOT FIGSIZE PYTHON HOW TO#

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.
