Hei @Image Analyst here are two data sets I have prepared. You can use any of them to create figure like (FIG 2). These datasets are attached here in the comment.

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(:) ;
p = pcolor(X,Y,Z) ;
p.EdgeColor = 'none' ;

@KSSV Is it possible to get with more close upper and lower limits with high resolution that also follow the small fluctuations... See the results with your code below. It more blur with respect to actual plot.
I have attached the actual data in refined form, can you try with it.
