MATLAB: Overlapping (intersection) of two points is wrong. It should depends on which value is higher.

overlapping intersection sort marker

My problem is: Some points are overlapping. But sometimes the overlapping of this points is wrong. The intersection of this 2 points should be filled with the color of the point with the higher value. The value is the third column of my data table. Thank you for your support.
Input_Matrix = textread('Rainflow_Input1.txt')
[zeilen,spalten]=size(Input_Matrix)
x = Input_Matrix(:,1)
y = Input_Matrix(:,2)
z = Input_Matrix(:,3)
colorbar('location','Manual', 'position', [0.93 0.1 0.02 0.81]);
a=30
scatter(x,y,a,z,'filled')
colorbar;

Best Answer

scatter3() and use the color as the z value. Then use view() to look down on it from above.
