I have plotted a particle map using the scatter plot using this code
%generated array of particles
x = 1:delta:10;
y = 1:delta:10;
shown_graph = zeros(length(x),length(y));
%plotting points into graph
[xpoint ypoint] = find(shown_graph == 0);
scatter(xpoint,ypoint,100,'.');
a problem i have with this method is that the particles are in a matrix format and not very helpful
is there a way to achieve the same result but in terms of x and y coordinates separately?
ie: (0,0),(0,1),(1,0),(1,1)... etc
such that i do not have to use the
shown_graph = zeros(length(x),length(y));
[xpoint ypoint] = find(shown_graph == 0);
part
instead
because i want to be able to vary the distance between the points

You need to be more clear about your question....
shown_graph = zeros(length(x),length(y));
%plotting points into graph
[xpoint ypoint] = find(shown_graph == 0);
scatter(xpoint,ypoint,100,'.');
The above lines are meaning less, you have intiated shown_graph as all zeros, and obviously when you seek zeros, you will get all the points. What exactly you are trying?
