Can you have two legends in MATLAB?

Accepted Answer 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.

  4. hold on y2 = sin(x – pi/4); p2 = plot(x,y2);
