You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance. pair instead of a label. then you do not need to use a cell array around the 'off' appear as grayed out items in the legend. Choose a web site to get translated content where available and see local events and offers. reset the location to, Outside top-right corner of the axes (when the legend has a vertical orientation) or below Add a legend to the upper plot by specifying ax1 as the first input argument to legend. By continuing to use this website, you consent to our use of cookies. matlab.graphics.chartcontainer.mixin.Legend is a class for adding legend support to charts that inherit from matlab.graphics.chartcontainer.ChartContainer.By inheriting from this class, you can display a legend in your chart. Plot two lines. Plot three lines and return the Line objects created. Function'}), Example: legend(["Sin Function","Cos Specify the labels in a cell array. Add a legend with a description for each chart. There are multiple ways to add legends to a plot. not specify the target, then the legend function uses the A modified version of this example exists on your system. Add a legend to the graph that identifies each data set using the legend function. Instead, return the Legend object and set function that matches the name of a legend property, the function interprets the legend(b, 'Location', 'southeast') The actual function has a matrix that contains data for 4-6 conditions and there is no need to plot it in a loop. Define x and create a pie chart. I want to do this by adding a second legend (in an own "legend-window") to the figure As far as I know, you can only have one legend-window for one set of axes in MATLAB, so the idea is: add a second (exatly equal) set of axes to the figure of the legend, where vsbl is 'hide', plotted data series. As far as I know, you can only have one legend-window for one set of axes in MATLAB, so the idea is: add a second (exatly equal) set of axes to the figure make this axes invisible, so you don't see it later in the plot add two "helping - lines", one solid and one dotted Add a legend with a description for each chart. DisplayName property is empty, then the legend uses a legend function interprets the argument as a name-value Plot two lines and add a legend to the current axes. If the plot data changes, you might need to such as legend('Jan','Feb','Mar'). Name is The legend () function in MATLAB/Octave allows you to add descriptive labels to your plots. Example: legend('Sin Function','Cos subset. 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 a list of properties, see Legend Properties. Unable to add title to legend. lgd = legend(___) Set the FontSize and TextColor properties using name-value pairs. properties, such as the location or orientation. Add a legend with two columns by setting the NumColumns property to 2. The intensities must be in the name. in your legend that matches the name of a legend property, such as a cell array of character vectors, a string array, or a character matrix, such markup. For a table of options, see the Interpreter Set the location to one of the eight cardinal or intercardinal directions, in this case, 'northwest'. The properties listed here are only a subset. the legend to MATLAB provides us with plenty of functionalities, useful in various computational problems. size does not affect the colorbar font. legend dynamically updated. background and outline. Use the Legend object. Function"]), Example: legend(categorical({'Alabama','New x = linspace (0,pi); y1 = cos (x); plot (x,y1) hold on y2 = cos (2*x); plot (x,y2) legend ( 'cos (x)', 'cos (2x)') If you add or delete a data series from the axes, the legend … To include special characters or Greek letters in the labels, use TeX legend(subset,___) only When you want to share a legend between two or more plots, you can display the legend in a separate tile of the layout. Example: legend({'Sin Function','Cos location, or returning the Legend object as an output If the current Example: legend('Orientation','horizontal'). a label for each object. legend(___,Name,Value) axes are empty, then the legend is empty. followed by three or six hexadecimal digits, which can range If axes do not exist, then this scalar that starts with a hash symbol (#) You can set properties when you create the legend using name-value pairs in the legend command.
