How to plot 3 different data in contour or pcolor ?

I have three different data

1. Time steps = 1X108 (should be in X-axis)
2. Data1 = 36X108 (should be in Y-axis(left))
3. Data2 = 36X108 (should be display in colour/countour/pcolor)

Now I want to plot temporal plot (colour plot ) like the image I attached

[Ameer Hamza]

Is data1 on y-axis 36x108 or 36x1? If it is 36x108, then is it in the form of a grid?

[Jeevan Kumar Bodaballa]

Data1 is 36X108

Data2 is 36X108

Actually I want to plot each coloumn in Data1 will show the values of each column in Data2 at each timestep.

I am sorry if I confuse you but if you don't understand pls ask me again where you missing.

Thank you for help :)

Can you attach the data in a .mat file? It will make it easy to understand the question.

[Jeevan Kumar Bodaballa]

here is the file I attached

data1 = nw_bin

data2 = sizdist

[Ameer Hamza]

something like this?

p = pcolor(dt, nw_bin, sizdist)
shading interp
xlabel('x');
ylabel('y');
colorbar

[Jeevan Kumar Bodaballa]

it worked

thank you and sorry for late response

Answer 1

[Ameer Hamza]

p = pcolor(dt, nw_bin, sizdist)
shading interp
xlabel('x');
ylabel('y');
colorbar

Can you try with “contourf” also ?

[Ameer Hamza]

Try this code

Dt = repmat(dt, 36, 1);
[dt_grid, nw_bin_grid] = meshgrid(dt, mean(nw_bin, 2));
sizdist_grid = griddata(Dt(:), nw_bin(:), sizdist(:), dt_grid, nw_bin_grid);
 
contourf(dt_grid, nw_bin_grid, sizdist_grid)
shading interp
xlabel('x');
ylabel('y');
colorbar
