#Python plot subplot how to#

This function returns a figure and an Axes object or an array of Axes objects. It is a wrapper function to make it convenient to create common layouts of subplots, including the enclosing figure object, in a single call. The function subplot create a figure and a set of subplots.

We will demonstrate in our examples how this can be accomplished with the funtion subplots. The idea is to have more than one graph in one window and each graph appears in its own subplot. The more interesting case is, if you want two plots beside of each other for example. This is not a problem, because it will be enough to put the two plots in your scripts, as we have seen before. In the simplest case this might mean, that you have one curve and you want another curve printed over it.

A frequently asked question is how to have multiple plots in one graph? We have given so far lots of examples for plotting graphs in the previous chapters of our Python tutorial on Matplotlib.

Subplots function become very handy when we are trying to create multiple plots in a single figure. So, our output has 4 subplots, arranged in the order we declared in the input. This is how our input and output will look like in python. Plt.plot(a, b, label = '2nd Straight line', color = 'red')Ĩ. Plt.plot(a, b, label = '1st Straight line') Plt.plot(x, z, label = 'cos function', c = 'red') (Here we have passed 2, 2 as first two numbers to get a 2 x 2 grid) Next, we will learn to create 4 subplots, for which we will need 2 x 2 grid.Ī = ī = Ĭ = This is how our input and output will look like in python.Īs we can see in our output, we have got 2 plots stacked vertically (a 2 x 1 grid).ħ. (Here we have passed 2, 1 as first two numbers to get a 2 x 1 grid) Let us take 2 functions, sine and cosine for this example Next, let us learn how can we place these plots vertically.įor this, we will have to create a 2 x 1 grid. Also, the subplots have taken respective positions as per our argument.ĥ. Plt.plot(c,d, label = 'cos function', c = 'red')Īs we can see, our output has 2 plots placed in 1 row and 2 columns as per our input argument. This is how our input and output will look like in python: Plt.plot(c,d, label = 'cos function', c = 'red') # Now the 3rd number will define the position of the 2 plots. So, in our example, the first 2 numbers are telling that we will have a grid of 1 row and 2 columns. The first 2 numbers passed in the argument define the dimensions of the grid in which we want our plots to be displayed. (Let us understand what exactly the function subplot(1, 2, 1) is doing.
