Enable this program (by handle) on an axes or a line object to activate graphical inspection of the data points in the plot or line object. When enabled, left-click and hold on a datapoint on the plot, and its x and y coordinates are displayed. (peekplot currently only works for 2-d plots). When the mouse button is released, the text will vanish. Click-and-drag to move the text to a more visible area if necessary, with a dashed-line trail to the original point. Peekplot cleans up after itself when terminated.
Peekplot works seamlessly with moveplot.m, but users must be sure to terminate the functions in the reverse order they are invoked (like a stack), e.g.:
%perform inspection and alteration
If moveplot is terminated before peekplot, both will be terminated at once.
Peekplot works with addplot, but not necessarily seamlessly. Addplot may be fixed in a later revision.
