If however you also want the colorbar to be left-aligned with the plot on top of it, the solution is probably more complicated. If the only aim is to get the height of the colorbar correctly aligned with its horizontal neighbor, the last solution from this answer would help. If greater than 1, it the absolute font size. without manually fiddling around with the dimension of the subplots holding the colorbar?ĮDIT: Increased width of colorbar to emphasize that it becomes smaller in height. If less than 1, it is the fraction of the . import matplotlib.pyplot as plt import numpy as np fig, axes plt.subplots(nrows2, ncols3, figsize(8.5, 5)) for ax in axes.flat: ax.setaxisoff() im ax.imshow(np.random.random( (16, 16)), cmap'viridis', vmin0, vmax1) fig.subplotsadjust(bottom0.1, top0.9, left0.1, right0.8, wspace0.02, hspace0.02) add an axes, lower left corner. I can plot the colorbar over the complete subplot, in which case the height is correct, but it's much to wide to be appealing.ĭoes anybody have a 'robust' solution, i.e. You can use plt.figure (figsize (16,8)) to change figure size of a single plot and with up to two subplots. Z, xedges, yedges = np.histogram2d(Z_random, Z_random, bins=bins, range=hrange, normed=True)įig, axes = plt.subplots(2,3, subplot_kw=dict(aspect='equal'))Ĭax = divider.append_axes('left', size='15%', pad=0.0)įig.colorbar(pcm, cax=cax, label=r'Colorbar label') This sets the size of the final image (including the visualization and, if applicable, the axes and colorbar as well) in inches. Z_random = np.random.multivariate_normal(mean, cov, size=n_samples) Note how the keyword argument projection3d is included in the fig.addsubplot() method. import numpy as np import matplotlib.pyplot as plt fig, axes plt.subplots (nrows2, ncols2) for ax in axes.flat: im ax.imshow (np.random.

#Pyplot colorbar offsets subplot size plus#

When using the axes divider recipe to attach the colorbar, the height of the subplot changes due to the aspect ratio. What was happening was that when I called the colorbar () function in either subplot1 or subplot2, it would autoscale the plot such that the colorbar plus the plot would fit inside the 'subplot' bounding box, causing the two side-by-side plots to be two very different sizes. I am using this recipe to generate a colorbar with a range suitable for all subplots hence this issue is not addressed in the MWE. However, I don't manage to get a narrow colorbar with the same height as the other subplots. The subplots have to have an equal aspect ratio and the colorbar has to have the same height as the subplots. yspacing / ysize List of y slice offsets subplots subplotcenters. I am trying to create a figure with several subplots that have a common colorbar. docsdef colormaphess(transition0.5, width0.1): Colormap often used in.
