How to display two sets of color data in the one picture using patch function?

two variables X and Yv are sets of color data, which share the same grid information. Now I want to display two sets of color data in the one picture using patch function. Can anyone help?

I want to achieve the following requirements through figure(4) : * X(e)>0.5 & Yv(e)<0.5 plot in one color, for example "red" * X(e)<0.5 & Yv(e)>0.5 plot in another color, for example "bule"

• X(e)<0.5 & Yv(e)>0.5 plot in "yellow"

if true
load('data.mat');
figure(1)
% colormap(gray);
patch('Faces',nodecon,'Vertices',nodexy,'FaceVertexCData',X,'FaceColor','flat','Edgecolor','none');
axis equal; axis off;pause(1e-6);

 figure(2)
 % colormap(gray);
 patch('Faces',nodecon,'Vertices',nodexy,'FaceVertexCData',Yv,'FaceColor','flat','Edgecolor','none');
 axis equal; axis off;pause(1e-6);

 figure(4)
 hold on; % axis equal;  axis off
 % colormap(gray);
 % colormap(jet)
for e=1:nelt    
    aabb=nodexy(nodecon(e,:),:) ;
    f = [1 2 3 4];
     if X(e)>0.5 & Yv(e)<0.5
        patch('Faces',f,'Vertices',aabb,'FaceColor','red')
     elseif X(e)<0.5 & Yv(e)>0.5
        patch('Faces',f,'Vertices',aabb,'FaceColor','green')
     elseif X(e)<0.5 & Yv(e)<0.5
        patch('Faces',f,'Vertices',aabb,'FaceColor','b')
    end 
end
axis equal; axis off;pause(1e-6);
end

Try creating an image instead of using patch().

Could you tell me how to create an image based on the present data? Thank you.
