How to plot a point on axes above current picture

When I use plot(x,y) function it erases the current data on axes and make blank white axes only with that point.

I would like to plot point above current data so both is visible.

Thanks.

   hold on

The above command allows you to plot data to your current axes without erasing previously plotted data.

If you have multiple axes, use the following:

   hold(my_axes,'on') %Where my_axes is the handle to your axes

Finally, "hold off" and "hold(my_axes,'off')" return the axes to the default setting, where previously plotted data is erased when you plot new data.

That is it!
