Now let’s add a blue line before the text and a black box around the text and the line. For example, let’s plot a cosine wave and put some text on it with font size 18 and red color. You can also change the properties of the text like the font size using the FontSize property and the color using the Color property etc. If you give the coordinates which don’t lie on the plot, you won’t be able to see the text. Simply plot the variable and then select the coordinates from the plot and then use the text() function to place the text on the selected coordinates. You need to pass the x and y coordinate on which you want to place the text.
We can also use the text() function to add text to the plot. Add Custom Legends Using the text() Function in MATLAB Check this link for more information about the legend() function. You can add as many legends as you want on a figure you just have to add more plots with undefined values on the same figure. In the above code, we added three legends on a cosine wave plot, and you can see they are not related to the plot. For example, let’s add custom legends to a cosine wave plot. You will not see the plots because their values are undefined, but you will see the legends. So to add custom legends that do not have any relation with the graph, you have to add more plots on the figure with undefined values, and then you can add more legends. If you try to add more than one legend using this function, MATLAB will give an error.
But the problem is it only adds one legend on one plot. The legend() function is used to add legends to a plot in MATLAB. Add Custom Legends Using the legend() Function in MATLAB
