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',[]);
