Now, the plot() function has been called. Now, the subplot() function of the pyplot package has been called with 2 rows, 1 column, and 1 subplot of the original plot. After this, we have added two axes of a plot using “x” and “y” and added values to both with the NumPy arrays separately. After this, we have added the NumPy support using its package import with the “n” object. So, we have started our new example with matplotlib.pyplot package import as object “p”. Now, let’s take a look at the subplot() function in python to create a subplot within the original plot. plot (x ,y, marker = "*", color = "red" )Īfter running the code, we have got the below plot in the console.
Subplot matplotlib example code#
Let’s save the code and execute it with the run button of Spyder. The marker is used to show the intersection point of both axes, and the color is used to draw the line in red. This function takes two more arguments, i.e. We have to use the pyplot libraries “plot()” function to create a plot with its axis. Both the arrays contain 4 elements of integer type and are saved to the respective axis. For this, we need to use the NumPy array with the NumPy object “n”. Now, we have to define the “x” and “y” axis for a plot. After that, we have been importing the NumPy package as an “n” object to utilize and add support for using the NumPy arrays in our code. So, we have imported the matplotlib.pyplot in our tool as object “p”. You need to know that in python, you cannot create a plot without importing the matplotlib.pyplot package in the python tool to make our code executable for graphs. Let’s get started with the very first example to see how a plot can be constructed in Spyder 3. Let’s do some examples of the subplot() method. The present plot’s index is represented by the third parameter. The subplots() method requires three inputs, specifying the figure’s arrangement. Another disadvantage of the subplot method is removing all previously created plots from your display. You will use the subplot() method in various code lines to make numerous plots. It is identical to a subplots() method, except instead of adding several subplots at once, it only inserts one at the moment. The method subplot() creates a subplot to an existing image at the provided grid location.
Subplot matplotlib example series#
If you want to create multiple sub plots in a single figure to show different aspects of a data, then the subplots() function should be used.The matplotlib.pyplot package is a series of methods that allow matplotlib to behave similarly to MATLAB. Let us understand the code of the live example which is given below in which we have plotted two sub plots. Let us cover a live example to understand this function in more detail. The output for the above code is as follows: With the given below code snippet, we will create a figure having 2 rows and 2 columns of subplots. Let us understand this method with the help of a few examples: Example 1: It can be an Axes object or an array of Axes objects. The values returned by these function are as follows:įig: This method is used to return the figure layout.Īx: This method is mainly used to return the axes. Matplotlib subplots() Function Returned Values This parameter is used to indicate the dict with keywords passed to the GridSpec constructor that is used to create the grid on which the subplots are placed on. This parameter is used to indicate the dict with keywords that are passed to the add_subplot call which is used to create each subplot. This optional parameter usually contains boolean values with the default is True. To control the sharing of properties among x (sharex) or among y (sharey) axis these parameters are used. The parameter nrows is used to indicate the number of rows and the parameter ncols is used to indicate the number of columns of the subplot grid. Let us discuss the parameters used by this function: The basic syntax to use this function is as follows: (nrows, ncols, sharex, sharey, squeeze, subplot_kw, gridspec_kw, **fig_kw) Matplotlib subplots() Function Parameters Various kind of subplots supported by matplotlib is 2x1 vertical, 2x1 horizontal or a 2x2 grid. The main objective of this function is to create a figure with a set of subplots. This function helps in creating common layouts of subplots and it also includes the enclosing figure object, in a single call. The subplots() function in the Matplotlib acts as a utility wrapper.
In this tutorial, we will cover the subplots() function in the state-based interface Pyplot in the Matplotlib Library.
