- You will need to have two plots per line (with each plot using one property) if you need two legends.
- Then add the legend for the first property by only using the lines that are representative of the first property.
- You can then use the 'copyobj' function to copy the legend and its axis.
- Then in the new axis you can change the legend in that handle to be the legend of only those lines that are representative of the second property.
- Make sure that both the legends are outside the plot. You can make one of the axis invisible if needed.
How can you have two different legend charts on the same plots with different titles?

I have a a figure where I am trying to plot 6 different graphs. 3 of these graphs belong to a particular subset which represent components x, y, and z. The other 3 below to another subset which also contain x,y , and z components. I would like to have two differnet legend plots on the same graph with a differnt title where the titles are 'Subset 1' and 'Subset 2'.

You can try the following approach:
ah = axes;
x = linspace(0, 3*pi);
y1 = sin(x);
y2 = sin(x - pi/4);
p1 = plot(x,y1);
p3 = plot(x,y1, '*');
p2 = plot(x,y2);
p4 = plot(x,y2,'+');
%% Plot the first legend
lh = legend(ah, [p1 p2], 'p1', 'p2');
%% Copy the axes and plot the second legned
ah2 = copyobj( ah, gcf);
lh2 = legend(ah2, [p3 p4], 'p3', 'p4');
