Text( 0.5, 0.5, '3', 'fontsize', 48 ) Simple example plot with three rows.įinally, we can create a full grid of sub-plots. Here is another example where I have swapped the first two arguments in the subplot function and now we will create a figure with three rows. Set( a3, 'fontsize', 16 ) Font sizes increase from left to right. This concept extends to all other plot axes properties and shows how each sub-plot can be fully customized.

The code snippet below is an example where the font is being set to a different size on each axes. For example, if we wanted to change the font size, we would have to specify the font size on each axes. 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. Notice in the code for this example that I have saved the axes handle (a1, a2, a3) for each of the subplots. Text( 0.5, 0.5, '3', 'fontsize', 48 ) Simple example plot with three columns. For convenience, I have also used the text() function to display the linear index in each subplot. Let’s start with a simple example that includes three sub-plots along a single row. It’s OK if this doesn’t make sense yet, the ordering is visualized in all of the examples within this section, especially in the grid example. The index starts at 1 and increases from left to right and top to bottom. The third argument is a linear index that selects the current active plot axes. The first two arguments define the number of rows and columns that will be included in the grid. The basic form of the subplot() command takes in three inputs: nRows, nCols, linearIndex. The subplot() function in MATLAB/Octave allows you to insert multiple plots on a grid within a single figure. The source code for the included examples can be found in the Git H ub repository. The provided examples should work in both MATLAB and Octave. In this tutorial, I describe three different ways to use the subplot() command and provide examples of each. They can also be used to quickly create interactive Graphical User Interfaces (GUIs). They allow users to very quickly create customized data visualizations and displays. You can change these properties according to your requirements using the function handle t1.Sub-plotting is a very powerful feature in MATLAB. In the above figure, you can see the font size, font name, and the color of the title are changed. Now let’s change the font size of the title to 18 using the FontSize property, the name of the font to Calibri using the FontName property, and the color of the title to green using the Color property. For example, let’s plot two subplots of sine and cosine waves on a figure and put a title above the two subplots. You can also change the font size of the text using the FontSize property, the color of the text using the Color property, and the name of the font using the FontName property. You can also use the suptitle() function which adds the given text above all the subplots on a given figure.

You can change these properties according to your requirements.
Sgtitle('Two Subplots','FontSize',28,'FontName','Times New Roman','Color','r') Now let’s change the font size of the title to 28 using the FontSize property, the name of the font to Times New Roman using the FontName property, and the color of the title to red using the Color property. In the above code, we used the subplot() function to plot two signals in a figure, and we used the title() function to give a title to each subplot and we used the sgtitle() function to add a title over both subplots. If you have a group of subplots and want to add a title over all the subplots, you can use the sgtitle() function, which adds the given string above all the subplots on a given figure.
