how to plot multiple curves on one graph

Hi,

I want to graph multiple curves on one graph. For example, one curve looks like:

x = [2,2,2,2,2]; (this represents number of vehicles)

y = [5,10,15,20,25]; (this represents number of nodes)

z = [6.3, 8.2, 7.3, 14.1, 73.4]; (this represents time taken)

This creates a curve that looks exponential, but I want to also overlay other curves like the following onto it (the overall graph should look almost like a ramp and a plot that shows the contour or surface would even be better).

x = [3,3,3,3,3];

y = [5,10,15,20,25];

z = [7.3, 10.2, 11.3, 22.1, 90.4]

Furthermore, if there is a way to fit an exponential curve to this, that would be even better.

Thank you so much for your help

plot3(x1,y1,z1,'b*-',x2,y2,z2,'ro:');

or

plot3(x1,y1,z1,'b*-');
hold on
plot3(x2,y2,z2,'ro:');
