I want to graph x=f(t) and y=g(t) but I want some sampling of values of t on the graph. Is there an option of plot command or a specialized program for doing this? So for example say x=cos(t), y=sin(t). I want to annotate the graph by putting t=0, t=pi/6, t=pi/4, etc on the graph. Of course this can be done by adding many text boxes to the graph but I was looking for a more automated solution.

Oh! Now I see what you're looking for. Unfortunately I don't know about an automated solution, all I can think of, is to write my own code to add annotations or text to the graph! But I don't think if that's gonna be ver usefull and beneficial code for me! :(

Mohsen, would this do (using ticks and tick labels)?
t = -pi:.1:pi;
y = sin(t);

The labels are to be on the graph, not on the axis. So for example x= cos(t) y= sin(t) will make a circle and on various points of the circle we want to write the value of parameter t. In general x=f(t), y=g(t) and t has a range of values. We want the the t values on the (x,y) plot.
