Hi,

I want to draw grid lines to a scatter plot only at tick '0'. The plot has x and y limits -1 to 1 and ticks at [-1 -0.75 -0.5 -0.25 0 0.25 0.5 0.75 1].

How could I do this without changing x- and y-ticks and without any additional major/minor grid lines?

How about using xline and yline functions?

The following is an example:

% Sample plot
figure
scatter(-1+2*rand(100,1),-1+2*rand(100,1))
ax = gca;
ax.XTick = -1:0.25:1;
ax.YTick = -1:0.25:1;
box on
% Add x = 0 and y = 0 lines
xline(0,'--')
yline(0,'--')
