current data.xls

Hello everyone!

I'm trying to plot a contour of sea current with time (in month) on the x axis vs depth (in meter) on the y axis.

The data (excel) is attached

I'v tried multiple times to do this but cant seem to work it out

Thanks in advance!!

[num,txt,raw] = xlsread('current data') ;
depth = num(:,1) ; 
currents = num(:,2:end) ;
[nx,ny] = size(currents) ;
%%plot of currents vs depth 
figure
hold on
for i = 1:ny
    x = 1:12 ;
    y = currents(i,:) ;
    z = depth(i)*ones(size(x)) ;
    plot(x,y,'color',rand(1,3))
end

It's good you have attached a image....

[num,txt,raw] = xlsread('current data') ;
depth = num(:,1) ; 
months = 1:12 ;
[X,Y] = meshgrid(months,depth) ;
currents = num(:,2:end) ;
contourf(X,Y,currents)
