hide legend for certain curves in a Matlab plot
显示 更早的评论
Hello everyone,
I have a little problem here, i plot 8 different curves on a figure but i want to hide the legend for the four last of them since they are only the new step of my simulation, does anybody has an idea to keep the legend for the first of them but hide it for the 4 last ones
