How to adjust Grid limits

I am trying to match each point in the x axis with the y axis.

I am proceding the following way:

 t = datenum(now):.5:datenum(now)+ 6
 x = sin(t)
 plot(t,x,'-ro')
 datetick('x',2,'keepticks');
 grid on

I want to keep the grid lines and add other grid lines highlighted with different colors marking the corresponding x value and y value in the graph.

Can you please help?

You need to play with the XTick and YTick axes properties.

set(hFig, 'XTick', [1 10 20 ....])
