legend for plot3 command
显示 更早的评论
I am going to plot two 3D data with the help of below command lines.
How can I insert legend for both the 3D data in a single window?
plot3(x,y,z);
hold on;
plot3(xx,yy,zz);

Use the DisplayName property of graphics objects to specify the legend string.
plot3(x,y,z, 'DisplayName', 'Object1');
hold on;
plot3(xx,yy,zz, 'DisplayName', 'Object2');
legend()
or
p1 = plot3(x,y,z, 'DisplayName', 'Object1');
hold on;
p2 = plot3(xx,yy,zz, 'DisplayName', 'Object2');
legend([p1,p2])

If p1 and p2 are not single objects, you can concatenate them vertically,
legend([p1;p2])
Or selection 1 element
legend([p1(1), p2(1)])
Is that what you're referring to?

I understood. My previous comment shows what to do under those circumstances.
Another alternative:
legend([p1(:);p2(:)])
