In Matlab R2014b the legend is no longer an axes object, and has no children. Legends are a useful way to label data series plotted on a graph. Then, use lgd to change the properties using dot notation. So you would take the trace you want to be second, cut and paste it, then do the same for the third, all the way to the Nth, and then the legend would have the desired order. 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). These examples show how to create a legend and make some common modifications, such as changing the location, setting the font size, and adding a title. That means that, if I open again the .fig file in Matlab, the size of the marker is just set to a default (tiny) size. It may be considered for a future release of MATLAB. I'm using different colors for each lambda value and different styles for each alpha value. Create a figure with a line chart and a scatter chart. In your case: color(lambda) and style (alpha). Specify the legend labels as inputs to the legend function. Learn more about legend, plotting, plot, multiple, copyobj, findobj Make sure that both the legends are outside the plot. I would like to have a horizontal legend below the X axis. Legend objects have properties that you can use to customize the appearance of the legend, such as the Location, Orientation, FontSize, and Title properties.

Plot two lines and add a legend to the current axes. legend associates strings with the objects in the axes in the same order that they are listed in the axes Children property. Then add the legend for the first property by only using the lines that are representative of the first property. Learn more about to If you need more labels, create a group for each per the other example "Grouping Objects to Reduce the Legend Entries". 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 updates accordingly.
