Legend matlab how to#

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, letР Р†Р вЂљРІвЂћСћs 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

In this tutorial, we will discuss how to add custom legends to the plot using the legend() and text() function in MATLAB.

By default hLegend.ItemTokenSize =, but we can either expand or shrink the icons/labels by setting different values. This is a 2-element numeric array specifying the minimal size of the legend entriesР Р†Р вЂљРІвЂћСћ icon and label. > get (hLegendIconLine ( end ) ) % LineStripР вЂќР вЂћn additional undocumented legend property that is of interest is ItemTokenSize. In the case of a LineStrip this includes LineStyle, LineWidth, ColorData (4Р вЂњРІР‚вЂќ1 uint8), and VertexData (which controls position/length): Still, I think that a direct reference in a hLegend.EntrР ВµРЎС™РЎС™ontainer.NodeChildren(1).Icon property would have helped in 99% of all cases, so that we wouldnР Р†Р вЂљРІвЂћСћt need to pass through the Transform object.Р вЂќР вЂћnyway, once we have this object reference(s), we can modify its/their properties. In the case of a line with markers, for example, hLegendIconLine would be an array of 2 objects: a LineStrip object and a separate Marker object. I assume that this was done to enable non-standard icons for patches and other complex objects (in which case the displayed icon would not necessarily be a LineStrip object). HLegendIconLine = .Children % a LineStrip object in our example HLegendEntry = hLegend.EntrР ВµРЎС™РЎС™ontainer.NodeChildren(1)

Children % a LineStrip object in our example To get all the original graphic objects together, in a single array, we could use one of two mechanisms (note the different order of the returned objects): Naturally, we can modify this order by creating the legend py passing it an array of handles that is ordered differently (see the documentation of the legend function). Note how the default legend entries order is the reverse of the order of creation of the original graphics objects. In my example above, hLegend.EntrР ВµРЎС™РЎС™ontainer.NodeChildren(2).Object = hLine1, and hLegend.EntrР ВµРЎС™РЎС™ontainer.NodeChildren(2).Object = hLine1. LayoutInfo: Р вЂќР’В®ach LegendEntry contains a back-reference to the original graphics object.
