At the top level, it is desirable for symmetry, but it also makes room for suptitle open in new window.įor the Subplotspec/Axes case, Axes often have colorbars or other annotations that need to be packaged inside the Subplotspec, hence the need for the outer layer. For the Gridspec case, a container is needed if the Gridspec is nested via GridSpecFromSubplotSpec open in new window. Why so many stacked containers? Ideally, all that would be needed are the Axes layout boxes. The second layoutbox corresponds to the Axes' ax.position, which sets where in the figure the spines are placed. The first one, ax._layoutbox represents the outside of the Axes and all its decorations (i.e. The nesting of gridspecs created with GridSpecFromSubplotSpec open in new window can be arbitrarily deep.Įach Axes open in new window has two layoutboxes. # Figure layoutĮach item has a layoutbox associated with it. ![]() The algorithm for the constraint is relatively straightforward, but has some complexity due to the complex ways we can layout a figure. If there is a bug, please report with a self-contained example that does not require outside data or dependencies (other than numpy). There is a bug - in which case open an issue at open in new window.There was not enough room for the elements you were requesting to draw.If this happens, it is for one of two reasons: The usual failure mode is for all sizes to collapse to their smallest allowable value. Because it uses a constraint solver the solver can find solutions that are mathematically correct, but that aren't at all what the user wants. There are small differences in how the backends handle rendering fonts, so the results will not be pixel-identical.Ĭonstrained-layout can fail in somewhat unexpected ways.This is often true, but there are rare cases where it is not. ![]() It assumes that the extra space needed for ticklabels, axis labels, and titles is independent of original location of axes.Thus, other artists may be clipped and also may overlap. constrained_layout only considers ticklabels, axis labels, titles, and legends.
