I am interested in knowing if there are any programs for X
Windows that will display X-Y data in connected point form as a
graph on the screen? I could see this being most useful for
visually following the performance of stocks and/or mutual funds.
It would be nice, too, if the Y-axis (vertical) could be
displayed in logorithmic units, rather than in linear units
(because logarithmic graphs have the property that the slope of
the curve represents the same percentage gain regardless of the
amount of the gain, whether it was $10 for a cheap stock or $100
for an expensive stock). In addition, it would be very desirable
if the program could scale/squeeze so all of the data (x,y)
points would fill the area in the window or it could "zoom" into
just a portion of the time-period (X-axis) of the graph for
closer inspection. Something like "xgraph <file", where file
contains lines of the form "X Y". Is it better to write a program
that directly calls X-Window promitives, or is is better to send
the escape sequences that xterm uses for Textronix 4014
emulation? I would guess the former were better. I am relatively
new to X, so please don't flame me if this question has been
asked before. Thanks in advance.
