Hi,
I have data file of the format.
x1 y1
x2 y2
x3 y3
....
I'm wondering how to connect them by arrows. I know that I can have
the data of the following form, so that it can be plotted as vectors.
I'm wondering if there is a more direct way to do it instead of by
manipulating the data.
x1 y1 x2-x1 y2-y1
....
Thanks,
Peng
