May 20, 2022 · subplot() function adds subplot to a current figure at the specified grid position. It is similar to the subplots() function however unlike subplots() it adds one subplot at a time. So to create multiple plots you will need several lines of code with the subplot() function.
The subplot() Function. The subplot() function takes three arguments that describes the layout of the figure. The layout is organized in rows and columns, which are represented by the first and second argument. The third argument represents the index of the current plot.

Up until now, you have probably made all your plots with the functions in matplotlib.pyplot i.e. all the functions that start with plt.. These work nicely when you draw one plot at a time. But to draw multiple plots on one Figure, you need to learn the underlying classes in matplotlib. Let’s look at an image that explains the main classes from the ...
The plt.subplots() function creates a Figure and a Numpy array of Subplots/Axes objects which we store in fig and axesrespectively. Specify the number of rows and columns you want with the nrows and ncolsarguments. This creates a Figure and Subplots in a 3×1 grid. The Numpy array axes is the same shape as the grid, in this case (3,). Access each Su...
To add an overall title to the Figure, use plt.suptitle(). To add a title to each Axes, you have two methods to choose from: 1. ax.set_title('bar') 2. ax.set(title='bar') In general, you can set anything you want on an Axes using either of these methods. I recommend using ax.set() because you can pass anysetter function to it as a keyword argument....
To share the x axis for subplots in matplotlib, set sharex=True in your plt.subplots()call. Here I created 3 line plots that show the linear, square root and exponential of the numbers 0-5. As I used the same numbers, it makes sense to share the x-axis. Here I wrote the same code but set sharex=False(the default behavior). Now there are unnecessary...
To add a legend to each Axes, you must 1. Label it using the labelkeyword 2. Call ax.legend() on the Axesyou want the legend to appear Let’s look at the same plot as above but add a legend to each Axes. The legend now tells you which function has been applied to the data. I used a for loop to call ax.legend() on each of the Axes. I could have done ...
You have total control over the size of subplots in matplotlib. You can either change the size of the entire Figure or the size of the Subplotsthemselves. First, let’s look at changing the Figure.
If you have used plt.subplot() before (I’ve written a whole tutorial on this too), you’ll know that the grids you create are limited. Each Subplot must be part of a regular grid i.e. of the form 1/x for some integer x. If you create a 2×1 grid, you have 2 rows and each row takes up 1/2 of the space. If you create a 3×2 grid, you have 6 subplots and...
If you aren’t happy with the spacing between plots that plt.tight_layout() provides, manually adjust the spacing with the matplotlib subplots_adjustfunction. It takes 6 optional, self explanatory arguments. Each is a float in the range [0.0, 1.0] and is a fraction of the font size: 1. left, right, bottom and top is the spacing on each side of the S...
Adding a colorbar to each Axes is similar to adding a legend. You store the ax.plot() call in a variable and pass it to fig.colorbar(). Colorbars are Figure methods since they are placed on the Figure itself and not the Axes. Yet, they do take up space from the Axesthey are placed on. Let’s look at an example. First, I generated two 10×10 arrays of...
I’ve spoken about GridSpec a few times in this article. It is the underlying class that specifies the geometry of the grid that a subplot can be placed in. You can create any shape you want using plt.subplots() and plt.subplot2grid(). But some of the more complex shapes are easier to create using GridSpec. If you want to become a total pro with mat...

plt.subplot is a Matplotlib function that allows us to create multiple subplots within a single figure. This can be useful when we want to compare different plots side by side or visualize multiple sets of data in a clear and organized manner.
Feb 7, 2020 · To create a matplotlib subplot with any number of rows and columns, use the plt.subplot () function. It takes 3 arguments, all of which are integers and positional only i.e. you cannot use keywords to specify them. plt.subplot (nrows, ncols, index) nrows – the number of rows. ncols – the number of columns.
pyplot.subplots and Figure.subplots: add a grid of Axes as in the example above. The pyplot version returns both the Figure object and an array of Axes. Note that fig, ax = plt.subplots() adds a single Axes to a Figure. pyplot.subplot_mosaic and Figure.subplot_mosaic: add a grid of named Axes and
