Contour/3d plots for large data sets

Hello,

I would like to generate a contour or 3-D plot for a large data set.

I have a matrix B, where size(B)= 483060 4

The parameters contained in B are as follows:

if true
time=B(:,1); %first column is temperature
sy=B(:,2); %second column is distnce in y
tl=B(:,3); %third column is temperature l
te=B(:,4); %fourth column is temperature e
 end

I would like to 3-D plot of both tl and te in time and space (sy).

I have tried contour3(time,sy,tl) but recieve the error

"Z must be at least a 2x2 matrix."

Best,

A

Try plot3 or scatter3

For a contour plot you need a nxn matrix

Thanks, I tried that and it gives me the right shape, however I would like to have a color associated with the intensity of a parameter (say, te). Any idea how to do this?

[Henrik]

scatter or scatter3 can do that.
