little more tinkering and correcting this
diff = start_time - end_time (vrs the other way around)
and its working.
so many thanks gents, a lot !

Passing Gnuplot.Data a Numeric array object is a good

this part " set xtics ("label" pos, "label" pos, "label" pos) "
is mainly what i was confused about. the 'pos' part. i think that the

If the x-axis is time, gnuplot will plot it correctly but it will connect
*all* the datapoints and scale the x-axis so that everything will fit on the
graph. Is it the autoscaling or conneting that what you think is wrong?

i know it formats a string.

this is great, because the docs on gnuplots website are a bit easier
for me to grasp.
thanks so much for your time on this one. you really have helped me a
lot.
i will not get a change to work on this till monday. so i may have more
questions then. This is sure a point in the right direction.

ok, i have a display, and its a work in progress.
lemme get this straight. you used

is this an example of sending normal gnuplot commands?
if so, are all of the gnuplot commands available ?

the time is DateTime.DateTime object from a mySQLdb query.
the value is a number anywhere between 0 and 15.
the datetime is formatted like 2005-10-20 08:40:34
i could strip it and make a timestamp out of it. but reading the
number of seconds since january of 1970 doesn't make a neat chart.

ok, i tried something similar to what you posted.
a little simpler though.
i am running a query on a database and making a list of time, value
pairs
kinda like this
plot_points = ([time, value], [time, value], [time, value])
gnuplot complains that it needs a float for one of the values.
i can plot
ok, yeah, thats exactly what i am looking for. i will give it a go.
thanks a whole lot.
putt this off is a typo, pull this off is what i was meaning to type.
this is cool.

I don't understand what you mean by "the time scale being
fixed". It's not. If you just pass the time,value pairs to

i have thought about doing this, just a little different. i was going
to list the value pairs.
take the start time and end time and plot 100 empty plots between them.
add the value pairs, sort by time, and then draw it. The only thing is

how ?
i have tried to use unix timestamps, and i have also tried with
DateTime objects
do i need to use a scale that isn't linear (default in most) ?
how do i putt this off ?
thanks btw.
