Realize a 3d line plot
显示 更早的评论
Hi all
i need to realize a 3d plot for displaying 3 connected quantities.
for i=1:length(i_ed)
for j=1:length(x)
if K1(i,j)>0
psl(i,j)=(70*(W_end_t(i)/Sr(i))*K1(i,j)*K2(i)*K3*acg(i))*1000;%N/m^2 RES22 (61)
end
end
end
plot3(L_end,x,psl)
xlabel('L')
ylabel('x')
zlabel('Psl')
hold on
where L_end has length(i_ed) elements. For better understanding the problem, x/L_end varies between very small values to 1. My goal it is to graph in the same 3d plot many curves as L_end length.
Thank you for the help!

You must be getting an error message. What does it say (all the red text)?
Check that your inputs are what plot3 expects.
- To plot a set of coordinates connected by line segments, specify X, Y, and Z as vectors of the same length.
- To plot multiple sets of coordinates on the same set of axes, specify at least one of X, Y, or Z as a matrix and the others as vectors.
In your case, it appears X and Y are vectors. Are they the same length?
Z appears to be a matrix. Do the number of rows match the lengths of X and Y?

No, it is not possible to plot vectors of different length.
They need to be the same length because they create a coordinate for each point.
There may be a different solution, but I'd need to know more about the data. Could you explain what values of X, Y and Z should be use to plot the 15th row of Z?

ok i see, let's try in this way... now suppose to have an y with this dimension 76800x14 double and x 76800x14 double.
This is Y:
This is X:
This is Z:

Try to plot it. What happens? How does that compare to what you want?
