Making a contour plot with 1-D z values?

I have experiemntal splash data with X being the Weber number Y being the Reynolds number and Z being a number (1-5) depending on the splash pattern. I am trying to vissulize this data by using a contour plot but cannot figure out to format my code since my Z is not a matrix. I have attached my data and any help would be greatly appreciated. I have been able to create the contour plot attached but I need smooth lines and only integers in the legend. I would like my plot to look like similar to the screen shot uploaded.

What is 'Splash data.txt'? How to read it?

Sorry about that I tried to reupload the data so it can be read. Let me know if 'Book1.txt' is readable.

You dont so much points for meshgrid, just make FaceColor - interp

F = scatteredInterpolant(Re,We,PS);
PSg = F(Reg,Weg);
h = pcolor(Reg,Weg,PSg);
set(h,'FaceColor','interp')
set(h,'EdgeCOlor','none')

caxis([0 5])
hc = colorbar;
set(hc,'YTick',0:5)
set(hc,'YTickLabel',0:5)
xlim([0 6000])
ylim([0 2000])

So this cleaned the graph up a little but is there a way to make the graph look like the screenshot I just uploaded?

You mean lines?

If you want to color some area - use patch()

[Bailey Basso]

Not sure if I totally know how to use patch() but I will work on it.

Just draw a line

h = patch(x,y,'r');
alpha(h,0.3)                % transparency
