How do you get information about any point (such as the values of the horizontal and vertical coordinates) from a Graph? Please give me a piece of LabTalk code, thank you!

You could use the range notation in LT to obtain the x,y values of a line/scatter plot:

range -wx rx = [Graph1]1!1;
range -wy ry = [Graph1]1!1;
rx[2]=;  // second point x value
ry[2]=;  // second point y value
