Matlab Plot Command Legend

Plot x y when you run the file matlab displays the following plot let us take one more example to plot the function y x 2.

Matlab plot command legend. Call the nexttile function to create an axes object and return the object as ax1 create the top plot by passing ax1 to the plot function. Use name value pairs in the legend command. Use name value pairs in the legend command. Use array operators instead of matrix operators for the best performance.

Add a title and y axis label to the plot by passing the axes to the title and ylabel. If the displayname property is empty then the legend uses a label of the form datan the legend automatically updates when you add or delete data series from the axes. Let us plot the simple function y x for the range of values for x from 0 to 100 with an increment of 5. For the labels the legend uses the text from the displayname properties of the data series.

In most cases when you use name value pairs you must specify the labels in a cell array such as legend label1 label2 fontsize 14. The function must accept a vector input argument and return a vector output argument of the same size. Create a script file and type the following code x 0 5 100. Optionally specify the legend location using one of the eight cardinal or intercardinal directions in this case southwest.

Use the legend object. In this example we will draw. Plot legends are essential for properly annotating your figures. Specify the legend descriptions in the order that you plot the lines.

Legend creates a legend with descriptive labels for each plotted data series. Function to plot specified as a function handle to a named or anonymous function. Legend positions the legend based on a variety of factors such as what objects the legend obscures. You can return the legend object as an output argument from the legend function such as lgd legend then use lgd with dot notation to set properties such as lgd fontsize 14.

Use the legend object. You can return the legend object as an output argument from the legend function such as lgd legend then use lgd with dot notation to set properties such as lgd fontsize 14. Add a legend to the graph that identifies each data set using the legend function. Luckily matlab octave include the legend function which provides some flexible and easy to use options for generating legends.

Specify a function of the form y f x. The source code for the included examples can be found in the github. Legend associates strings with the objects in the axes in the same order that they are listed in the axes children property. In most cases when you use name value pairs you must specify the labels in a cell array such as legend label1 label2 fontsize 14.

For example use times instead of. Matlab displays only one legend per axes. By default the legend annotates the current axes.
