How can i plot coordinate point in mutiple color?

i need to plot this coordinate in different color. i assume that column1,2,3 is x,y,z axis

If value in y is in 0.0024<x<0.0032 it will keep data in x y and z and show green.

If value in y is less than 0.0024 it will keep data in x y and z and show red.

If value in y is more than 0.0032 it will keep data in x y and z and show blue.

now i use pcshow function and i cant seperate color in different point of data.

x = rand(100,1) ; 
y = rand(100,1) ; 

figure
hold on
plot(x(y<=0.4),y(y<=0.4),'*r') 
plot(x(y>0.4&y<0.7),y(y>0.4&y<0.7),'*b') 
plot(x(y>=0.7),y(y>=0.7),'*g')
