Hi Rooters,

I am working with Bloomber terminal ( a system supplying financial
information and data) and I found a nice feature of its graphical screen
which can be interesting for everybody. The point is that if you have
data in a range [Xmin, Xmax] and [Ymin, YMax] and plot a graph in a
window of [x1, x2] [y1,y2], you can just click with a mouse on a graph
(or in any place of a graph window) and then "drag" or "slide" the
contents of the graph window with the mouse. I mean if you have
|
|                 *
|  ------------
   5     10    15

on X axis and want to see data in 10-20 instead of 5-15

|
|           *
|  -------------
  10     15    20

you just click somewhere inside the pad and "drag" the contents of the
pad to the left.

I think this is just a few lines of code (basically changing pad range
on mouse press and move) but the effect is quite useful and together
with present zoom you can rock and roll. Also, in Bloomberg you unzoom
automatically if you double click inside a pad. This seems to be a good
feature too.

Comments?
