Still no one could help me with this question. I have a .csv file with 3 columns of different range of data. Each column contains 500,000 rows including some duplicate numbers. I am trying to plot a color plot like the one I attached here. A triangular color plot, like conotur map.

Hello Farshad,
I am too looking for getting a triangular plot. Did you made any more progress on that, if so then kindly share the script for my reference. Your help is appreciated Thank you

Let A be your m*3 column array. Try this:
x = A(:,1) ; y = A(:,2) ; z = A(:,3) ;
%%structured
xi = unique(x) ; yi = unique(y) ;
[X,Y] = meshgrid(xi,yi) ;
Z = reshape(z,size(X)) ;
figure
surf(X,Y,Z)
%%unstructured
dt = delaunayTriangulation(x,y) ;
tri = dt.ConnectivityList ;
figure
trisurf(tri,x,y,z)
%% USe Interpoaltion
m = 100 ; n = 100 ;
xi = linspace(min(x),max(x),m) ;
yi = linspace(min(y),max(y),n) ;
[X,Y] = meshgrid(xi,yi) ;
Z = griddata(x,y,z,X,Y) ;
pcolor(X,Y,Z)
shading interp
colorbar

If you know the triangular dimension.......make the vertices....use inpolygon and pick only the points inside this triangle and plot.
