I'm trying to make grids in my plot, i have other simpler plots where i manage to show grids, but not in this plot:
%The AXES command selects the set of axes to plot in,
axes(handles.viewCAM_handles.axes_accVelRatio);
% Plot velV and accV ratio with centered x and y axis
[AX] = plot(velV, accV);
grid on;
set(AX, 'LineWidth', 2);
xlabel('Velocity');
ylabel('Acceleration', 'Color', 'b');
xMax = max([max(velV) abs(min(velV))]);
yMax = max([max(accV) abs(min(accV))]);
if xMax >= 1
xMax = ceil(xMax);
else
xMax = round(xMax*10)/10;
end
if yMax >= 1
yMax = ceil(yMax);
else
yMax = round(yMax*10)/10;
end
axis([-xMax xMax -yMax yMax]);
y=get(gca,'ytick');
x=get(gca,'xtick');
hold on
Lx=line([x(1) x(length(x))],[0 0]);
Ly=line([0 0],[y(1) y(length(y))]);
set(Lx,'color','k');
set(Ly,'color','k');
for i=1:length(x)
plot(x(i),0,'kx');
text(x(i),-.01,num2str(x(i)));
end
for i=1:length(y)
plot(0,y(i),'kx');
text(-0.5,y(i),num2str(y(i)));
end
grid on;
set(gca,'yticklabel',[],'xticklabel',[],'ytick',[],'xtick',[]);
I'm setting origo in the middle of the plot and i draw lines for that, i think the problem has something to do with that. Any ideas?
My plot look like this:

I debugged the code and before the last line of the code i posted, the grid is showing, but not after the last line.

If you set all the ticks to empty you will have no grid by definition as the grid is defined to be at the tick locations

Thx, changing the last line to this fixed it:
set(gca,'yticklabel',[],'xticklabel',[]);
