Hi,
I suppose... Let's say, once you make two tables of values and you decide create a scatter plot, where the row values of one table is plotted against the row values the other... how can you use scatter to plot only the non-zero points in the tables?
For instance,
I had:
x1 = tt5{:,6}
y1 = ss5{:,6}
scatter(x1,y1,'b')
hold on
where
ss5 column 6:
0
1
0
0
1
0
0
0
tt5 column 6:
0
7
6
5
18
6
4
5
So, I would only want to plot (7,1) and (18,1)

Either will do ;)
It is just a bit frustrating to apply formatting to your question, and then having to do it again because you removed everything including the formatting. The edit controls are right there when you edit you posts, please use them.

Here's how to do this with a small example script:
% create a 5x2 array of random integers 0-5 for both x and y
x = randi([0 5],5,2);
y = randi([0 5],5,2);
% identify indices where both x and y are not zero
idx = (x ~= 0) & (y ~= 0);
% plot only these
scatter(x(idx),y(idx))
If this doesn't work with your code, please work to simplify it as Rik suggests
