@Nisar Ahmed make it EASY for people to help you and they will. If you don't want to share your actual data, then make up something, like a for loop where you create a bunch of noisy sine waves or something. Don't make other people do that just to help you. You should do that for them, otherwise they'll just move on to another question.
There is nothing built in to MATLAB that does that so you'll have to use custom code. I know there was a question on that a few years ago and I answered it but I don't have the link right now.

How about this approach?
load('p0_t.mat') ;
x = t ;
y0 = min(p0(:)) ;
y1 = max(p0(:)) ;
y = linspace(y0,y1,300) ;
[X,Y] = meshgrid(x,y) ;
Z = NaN(size(X));
tt = repelem(t,7,1) ;
tt = tt' ;
m = 70 ; % can be changed
idx = knnsearch([X(:) Y(:)],[tt(:) p0(:)],'k',m) ;
for i = 1:m
Z(idx(:,i)) = p0(:) ;
end
p = pcolor(X,Y,Z) ;
p.EdgeColor = 'none' ;
