How to get scrolling plot in Linux (using command-line tools)?
- by Vi
Supposing I have a program that prints lines with data periodically, how can I turn then info them into graphical plot that updates itself each time new line available?
$ ./prog
10 44
20 66
30 55
40 58
50 59
55 58
60 77
^C
$ ./prog | scrollingplot
Window appears and updates on each line printed:
80|
| ----
| ---- ______...__/
| / -----
| -
40|
-------------------------------
10 20 30 40 50 60
# Note that ASCII art-style plot is just for example,
# I want simple X window like in mplayer.
There are enough tools for static data, but I haven't seen ones for updating data (except of ksysguard).
