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. This command creates a legend in the current axes, which is returned by the gca command. If the current axes is empty, then the legend is empty.

If you do not want the legend to automatically update, set the AutoUpdate property of the legend to 'off'.

Syntax legend ' string1 ',' string2 ', For each line plotted, the legend shows a sample of the line type, marker symbol, and color beside the text label you specify. When plotting filled areas patch or surface objects , the legend contains a sample of the face color next to the text label. If no legend exists for the current axes, one is created using default strings. The default string for an object is the value of the object's DisplayName property, if you have defined a value for DisplayName which you can do using the Property Editor or calling set. Otherwise, legend constructs a sting of the form data1 , data2 , etc. The location string can be all lower case and can be abbreviated by sentinel letter e.

Legends play a vital role in aiding the understanding of plotted data and providing context and clarity to the information being presented. The legend function in MATLAB is a valuable tool used to add legends to a plot, aiding in the interpretation of data and enhancing the visualization. Its basic syntax is as follows:. These additional plots serve as placeholders, allowing the inclusion of multiple legends. In this provided code, we begin by creating a time vector t using the colon operator, generating values from 1 to 2 with a step size of 0. To prepare for adding custom legends unrelated to this plot, we employ hold on , ensuring subsequent plots are added to the existing figure. Then, we generate three additional plots using plot NaN,NaN , essentially creating dummy plots with undefined values. After setting up the placeholder plots, hold off is used to disable the hold state, allowing any subsequent plots to replace the current plot. Finally, we utilize legend with the placeholder plot handles p and assign custom labels 'Cos1' , 'Cos2' , and 'Cos3' to create the desired custom legends.

The elements to be added to the legend are automatically determined, when you do not pass in any extra arguments. In this case, the labels are taken from the artist. A string starting with an underscore is the default label for all artists, so calling Axes. For full control of which artists have a legend entry, it is possible to pass an iterable of legend artists followed by an iterable of legend labels respectively:. This call signature is discouraged, because the relation between plot elements and labels is only implicit by their order and can easily be mixed up. To make a legend for all artists on an Axes, call this function with an iterable of strings, one for each legend item. For example:. A list of Artists lines, patches to be added to the legend. Use this together with labels , if you need full control on what is shown in the legend and the automatic mechanism described above is not sufficient.

Background color, specified as an RGB triplet, a hexadecimal color code, a color name, or a short name. But the legend wouldn't move at all. Search Support Clear Filters. Text interpreter, specified as one of these values: 'tex' — Interpret characters using a subset of TeX markup. Create a legend and assign the Legend object to the variable lgd. To move the legend to a different tile, set the Layout property of the legend. In this example, the plot command specifies a solid, red line ' - r' for the cosine function and a dash-dot, blue line ' -. Si desea tener en su leyenda una etiqueta que coincida con el nombre de una propiedad de leyenda, como 'NumColumns' , especifique todas las etiquetas en un arreglo de celdas. Jonas on 16 Sep Use lgd to query and set properties of the legend after it is created.
