The easy way is to exploit the y-labels and titles of the plot and then use fig.tight_layout () to make room for the labels. This is accomplished by passing in an array of linear indices as third argument, rather than just a single value. Specify pos as a four-element vector of the form [left The first subplot is the first column of the first row, the second subplot is the second column of the first row, and so on. They can also be used to quickly create interactive Graphical User Interfaces (GUIs). However, you can use the hold on command to combine multiple plots in the same axes. Specifying sub-plots in this manner allows you to have complete control over the position and is essential if you want to programmatically create GUIs. How can we achieve this layout, where, essentially some subplots span across several rows/columns of the overall figure? we use pyplot.subplot_mosaic, and use the subplot labels The third argument represents the index of the current plot. They allow users to very quickly create customized data visualizations and displays. No problem in R2014b either. subplot(ax) makes Approach.

If axes exist in the specified position, then this command makes the axes the current axes. Do you know how I can fix this? Given the number of rows and columns, it returns a tuple (fig, ax), giving a single figure fig with an array of axes ax. How to Add Title to Subplots in Matplotlib? This is important because now that there are multiple plot axes on the figure, we will need to specify which axes we are referencing whenever we change properties. The figures fit within the space of each subplot, so it shouldn't obstruct the labels overrides the previous setting of the lables. subplot(m,n,p,ax) converts Then replace the second subplot with empty axes. Store the Axes objects in vector ax. The third argument is a linear index that selects the current active plot axes. subplot(m,n,p,'replace') deletes then subplot creates a subplot that spans the grid columns. The code snippet below is an example where the font is being set to a different size on each axes. For Y-label, I used the following code: .
