"grid on displays the major grid lines for the current axes or chart returned by the gca command. Major grid lines extend from each tick mark."

You can use xticks() and yticks() to specify the position of the x ticks and y ticks (which in turn will be the positions the grid lines are drawn.) You can use xticklabels() and yticklabels() to set the tick labels to empty so that there will only be the grid lines.

MATLAB put grid lines at every XTick or YTick position. You can set the axes XTick and YTick properties to change where the grid lines are to go.

For example:

   number_interior_x_gridlines = 7;
   ax = gca;
   XL = get(ax, 'XLim');
   xticks_at = linspace(XL(1), XL, number_interior_x_gridlines + 2);
   set(ax, 'XTick', xticks_at);

Plotting lots of lines is not the correct solution, you should use the grid command, or set the axes grid properties (e.g. adjust tick-mark positions, grid linestyle, grid color, grid transparency, etc.). The MATLAB documentation gives examples of how to adjust the grid lines:

This should get you started:

>> x = -10:0.1:10;
>> y = 100*sin(x);
>> plot(x,y,'-.')
>> ylim([-150,150])
>> set(gca,'YGrid','on') % Turn on the Y-grid. Also: color, linestyle, etc.
