better way of contouring velocity magnitude with time as x axis
===

I am not getting a nice pcolor plot, so i need to do a contour plot of velocity magnitude with depth (contour lines) and time as x axis. I know that there are other options but i prefer contour plot.

    figure;
    
    timeC = x(in);                %  811 X 1 matrix
    depC = [1.20,2.20,3.20];
    depC = depC';                 % 3 X 1 matrix
    
    
    ur = dat3(in,1:3);            % 811 X 3 matrix
    vr = dat4(in,1:3);            % 811 X 3 matrix
    [THETAc,Rc] = cart2pol(vr,ur);
    vMag = Rc';                   % 3 X 811 matrix
    
    hpc = pcolor(timeC,depC,vMag);
    set(gca,'YDir','reverse');
    set(hpc,'EdgeColor','none');
    caxis([0,0.2]);
    t = colorbar('peer',gca);
    set(gca, 'xlim', [min(timeC) max(timeC)]);
    datetick(handles.axes4,'x', 15, 'keeplimits'); % does not work with pcolor
