It’s important to note that this feature is still in testing and (at the time of this posting) is not currently supported by many distributions such as Anaconda. The subplot_mosaic has a simple and streamlined interface that allows you to easily lay out subplots, then stores these subplots as a dictionary. Matplotlib recently introduced a new feature, subplot_mosaic, which allows a more intuitive interface for configuring subplots. ![]() While Gridspec can create complex configurations of subplots, manually adjusting the grid can become complicated for complex layouts. In my last post I discussed the Gridspec interface, which allows you to manually configure custom grid of subplots. For more on colorbars, see the documentation here. I should note that we can edit the colorbar axes object just like any of the other axes objects, adding labels, adjusting the tick marks etc. Applying constrained layout to this set of subplots fixes the error and creates a nice looking set of plots.įig, axes = plt.subplots(2,2, figsize=(8,8), constrained_layout=True) Constrained layout should be called during the creation of the figure object, as demonstrated below. Luckily, there is an alternative to tight_layout, called constrained_layout, which uses a constrained solver to optimize subplot placement. The result will look like this (and produce an warning output): This will make things worse however, because the colorbar confuses the algorithm that tight_layout uses to arrange the axes objects. One way you may attempt to fix this could be to use the tight_layout() function, which can help align subplots. Unfortunately, with the default settings, this code will shrink two subplots disproportionately.įrom mpl_toolkits.axes_grid1 import make_axes_locatableįig, axes = plt.subplots(2,2, figsize=(8,8))Ĭbar = fig.colorbar(im1, ax=axes, shrink=0.8) The fig.colorbar() function, allows you to easily add a colorbar to the set of subplots. Here’s an example of creating a single colorbar for four different subplots. ![]() Making a colorbar in matplotlib is fairly easy, but unless you use the right tools, making the colorbar fit into the overall graphic can be unexpectedly difficult. Often, you may use a common color to link multiple views of the same data set, or contrast two data sets. Formatting colorbars with constrained_layoutĬolorbars play an important role in data visualization. This feature is still in its testing phase, but will likely be the new standard for making subplots in the future. Then I’ll discuss a brand new feature of Matplotlib, the subplot_mosaic interface. If nrows, ncols and index are all less than 10, they can also be given as a single. Indexes go from 1 to nrows ncols, incrementing in row-major order. In the current figure, create and return an Axes, at position index of a (virtual) grid of nrows by ncols axes. First, I’ll discuss working with colorbars, a seemly minor task that can be quite time consuming. Return a subplot axes at the given grid position. In this post I’ll go over two more subplot tools that are helpful for designing informative and attractive subplots. Combining two subplots using subplots and GridSpec Using Gridspec to make multi-column/row subplot layouts Nested Gridspecs Invert Axes Managing multiple figures in pyplot Secondary Axis Sharing axis limits and views Shared axis Figure subfigures Multiple subplots Subplots spacings and margins Creating multiple subplots using plt. While the information in that post can allow you to do quite a lot, there is in fact more that you might want to know.
