Plot Function Matlab Legend

Specify a function of the form y f x.

Plot function matlab legend.

All we need to do is pass the pre defined code for the direction as an argument. Matlab function reference. Legend creates a legend with descriptive labels for each plotted data series. Let us learn how to achieve that.

Call the tiledlayout function to create a 2 by 1 tiled chart layout. Add a title and y axis label to the plot by passing the axes to the title and ylabel. By default the legend annotates the current axes. 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 array operators instead of matrix operators for the best performance. Example 3 next what if we don t want our labels to be on the top right but in some other place on the plot. Starting in r2019b you can display a tiling of plots using the tiledlayout and nexttile functions. Control the resolution of a plot by using the meshdensity option.

Increasing meshdensity can make smoother more accurate plots while decreasing it can increase plotting speed. Matlab displays only one legend per axes. Use name value pairs in the legend command. In this article i cover the basic use of the legend function as well as some special cases that i tend to use regularly.

For the labels the legend uses the text from the displayname properties of the data series. Matlab displays only one legend per axes. Divide a figure into two by using subplot in the first subplot plot a step function from x 2 1 to x 2 15 the plot s resolution is too low to detect the step function. Legend function in matlab allows us to put our label in place of our choice.

For example use times instead of. Legend associates strings with the objects in the axes in the same order that they are listed in the axes children property. The function must accept a vector input argument and return a vector output argument of the same size. 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.

Luckily matlab octave include the legend function which provides some flexible and easy to use options for generating legends. Displays a legend on the plot containing the objects identified by the handles in the vector h and using the specified strings to label the corresponding graphics object line barseries etc. Legend positions the legend based on a variety of factors such as what objects the legend obscures. Use the legend object.

Plot legends are essential for properly annotating your figures. Control resolution of plot. 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. 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.
