[Gnuplot-info] How to extend the X axis longer so that the output file would actually look bigger and longer

[Sara K. <sar...@gm...>]

Hi all,

I got gnuplot last night and have been working with it since this afternoon.
 I enjoyed it a lot.

But I still need to figure out:

How to make the x axis look longer in the plot or more importantly in the
out put file. I am plotting the data from a long range of dates and if it
keeps putting them in a small standard size plot nothing could be understood
from the plot.

I tried it with excel and when the graph is 9240*291 pixels, it gets
readable. But now the gnuplot graph is 640* 480 and I do not know how to set
the x axis to be longer.

Right now my x axis looks like:
set xdata time
set timefmt "%b %d %H:%M\t"
set format x "%b %d %H:%M"
set xlabel "Date & Time"
set xrange [*:*]


what is the command to make it longer?


Thank you,
Sara

if the terminal you are using is supporting the 'size' option:

set terminal ... size x,y

have a look the documentation of your terminal.

You gotta be kidding.  There's no way a file 9000 pixels wide is 
"readable".  It won't fit on any kind of screen you're ever likely to 
get.  If you rescale it down far enough to fit, the letters will be 
squashed into unreadability.  If you zoom in, 80% or so of it will be 
invisible.  That's no way to establish readability.

That's quite wide for a tick label, which risks that neighboring labels 
will run into another.  You'll want to make that narrower, e.g. print it 
in two-line format:

	set format x "%b %d\n%H:%M"

or rotate it:

	set xtics rotate

Thanks all.


I tried

set term gif size 9240,291
set output "public_html/test.gif"

and it worked out.
Once you click on it on the website, it shows so small and then you can
click on it, it zooms and you can scroll and go forward. It is all clear.
