I think the solution is in this line (I found it in another community) but I dont no how to change it: a=axes('position',get(gca,'position'),'visible','off'); Thanks! Three years ago I explained how we can use a couple of undocumented hidden properties of the legend in order to add a legend title (the legend object had no Title property back then – this was only added in a later Matlab release, perhaps as a result of my post). The legend() function in MATLAB/Octave allows you to add descriptive labels to your plots. Learn more about to Legend guide¶. Then use 'legend('nabla1', 'nabla2',...)' to draw the legend, the nablas have to be in the right order, tho.

Add a legend with a description for each chart. Today my colleague Roshin Kadanna Pally is back to talk about additions he made to the Simulink Scope in R2012a. But it displaying only alpha value at the end. Use name-value pairs in the legend command. If you need more labels, create a group for each per the other example "Grouping Objects to Reduce the Legend Entries". You can return the Legend object as an output argument from the legend function, such as lgd = legend. the type of point corresponds to sample{j} ). To include a variable value in the text, use “num2str”. 0 ⋮ Vote. legend installs a figure ResizeFcn, if there is not already a user-defined ResizeFcn assigned to the figure.
