See, since autoranging is done after all functions/data are evaluated, why
not exclude the special case *,u 3:(?)(?),* from evaluating the GPVAL
parameters, which I don't think is a problem to realize, then the system
automaticall assign the GPVAL_Y_MIN+0.5*(GPVAL_Y_MAX-GPVAL_Y_MIN) and
0.5*(GPVAL_Y_MAX-GPVAL_Y_MIN) to the two question marks, and then return
back to the normal path

Re: could gnuplot provide some specific functions?

2009-11-25T14:27:39Z

sure, the plot ranges are determined and are accessible via some
variables, e.g. GPVAL_Y_MIN, GPVAL_Y_MAX, a.s.o.

but, these variables are set after all functions/data are evaluated,
not before.

otherwise it would be easy:

plot "datafilename" using 1:2, \
"" using 3:\
(GPVAL_Y_MIN+0.5*(GPVAL_Y_MAX-GPVAL_Y_MIN)):\
(0.5*(GPVAL_Y_MAX-GPVAL_Y_MIN))

but this doesn't work, because at the time these variable are
used here, they are unset - because autoranging is done after
all functions/data are evaluated

you could do a dummy plot (set term dumb), where you plot
everything except the vertical lines. this would set the axis ranges.
and then you would do the real plot, this time with the (errorbars
as) vertical lines:

set term push
set term dumb
plot "datafilename" using 1:2
set term pop
plot "datafilename" using 1:2, \
"" using 3:\
(GPVAL_Y_MIN+0.5*(GPVAL_Y_MAX-GPVAL_Y_MIN)):\
(0.5*(GPVAL_Y_MAX-GPVAL_Y_MIN)) with errorbars pointtype 0

bsmile wrote:

Thanks, this should serve the purpose.

But still if could the system automatically determine the range of the y
values, say

u 3:(?):(?), then system automatically determines ( ...y=? ...) = mean of
the y range in the other plots, or in default at 0, (...yerr=? ...) =
standard deviation of y values in the other plots, or in default at 1.

it seems to me the above functionality is not hard to implement since there
has been use of (), if there could be a check for ? during syntax sparse,
then accumulate mean and/or std from other column of output. It seems to me
adding this functionality does not interfere with other existing
functionalities ..

font sizes for keys?

2009-11-25T08:01:30Z

Hi

How can i assign a font size to the keys (the legend in the upper right),
that is different from the size used tow write the numbers on th axes
and the labels?

Thank You
Jody

Re: wgnuplot 4.3+ persistent processes

2009-11-25T07:11:52Z

I tried this with a different terminal type (windows) instead of wxt, and did not see the same behavior, so perhaps it is a bug with the wxt terminal in windows. I attempted other terminal types, but couldn't get any other ones to run with the 4.3 or 4.5 win32 binaries.

Hello,

I have a program that spawns a wgnuplot process by: "wgnuplot datafile.gp -" in MS Windows.

For version 4.2, the spawned wgnuplot process gets killed when the plot window is closed. For version 4.3+ the plot window goes away, but the wgnuplot process sticks around. This causes problems after a while as there end up being many wgnuplot processes running in the background. Did something change between 4.2 and 4.3+ that would cause this behavior? The only other difference is that I'm running the 4.3+ wgnuplot with a datafile.gp that adds the enhanced, size, and title arguments to the set term wxt command.

I know that the third column has identical value say at 5, then I hope the
whatever is the special symbol which draws a vertical line through x=5

whatever is used, it will still draw a vertical line through x_mean for
column 3.

because a function assigns one (or no) y-value to a x-value.
a vertical line can not be described by a function.

2009-11-24T11:45:28Z

say, vertical line, which can draw a vertical line at specific x position automatically ranging through the plotted region? So far, vertical lines can be drawn, but have to be tricky, if not lengthy. Since gnuplot is famous for its convenience, why not introduce a simple function to accomplish plotting vertical lines?

Re: Combining a 3D and a 2D splot with no surface

set surface

Hi all,

I'm trying to combine the plotting of a heightmap (using contourlines) and
a line.

The .plot file basically is as follows:

set size square
set data style lines
set pm3d at b interpolate 10,10
set contour
set cntrparam bspline
set view map
unset surface
splot "results.dat" using ($2):($3):($1) notitle, "line.dat" using 1:2:(0)

The results.dat file contains X, Y and Z values, the line.dat file (which
represent a line y = 2-x) only contains X and Y values, with the Z value,
as you can see, set at a constant of 0.

I use 'unset surface' because otherwise a grid-like figure through the
datapoints in results.dat will be plotted, which is very much undesirable
in my case. However, this also means that the line represented by line.dat
is not plotted. Is this in any way avoidable? That is, can I draw the line
in line.dat without also having the plot the grid-like figure?

Kind regards,

Michiel

wgnuplot 4.3+ persistent processes

2009-11-24T11:31:10Z

Hello,

I have a program that spawns a wgnuplot process by: "wgnuplot datafile.gp -" in MS Windows.

For version 4.2, the spawned wgnuplot process gets killed when the plot window is closed. For version 4.3+ the plot window goes away, but the wgnuplot process sticks around. This causes problems after a while as there end up being many wgnuplot processes running in the background. Did something change between 4.2 and 4.3+ that would cause this behavior? The only other difference is that I'm running the 4.3+ wgnuplot with a datafile.gp that adds the enhanced, size, and title arguments to the set term wxt command.

Combining a 3D and a 2D splot with no surface

2009-11-24T07:39:04Z

Hi all,

I'm trying to combine the plotting of a heightmap (using contourlines) and

The .plot file basically is as follows:

set size square

set view map
unset surface
splot "results.dat" using ($2):($3):($1) notitle, "line.dat" using 1:2:(0)

The results.dat file contains X, Y and Z values, the line.dat file (which
represent a line y = 2-x) only contains X and Y values, with the Z value,
as you can see, set at a constant of 0.

I use 'unset surface' because otherwise a grid-like figure through the
datapoints in results.dat will be plotted, which is very much undesirable
in my case. However, this also means that the line represented by line.dat
is not plotted. Is this in any way avoidable? That is, can I draw the line
in line.dat without also having the plot the grid-like figure?

that's not so easy...
the outer double quotes are needed to make clear that the
result of the 'date' command is a string:

print `date -d "-$(($(date +%d)-1)) days" +%Y-%m-%d`
1997
print "`date -d "-$(($(date +%d)-1)) days" +%Y-%m-%d`"
2009-11-01

single quotes would not work here, because then the backquotes
would not be interpreted (by gnuplot):

print '`date -d "-$(($(date +%d)-1)) days" +%Y-%m-%d`'
`date -d "-$(($(date +%d)-1)) days" +%Y-%m-%d`

the double quotes inside the backquotes are essential, single
quotes would work here (due to the expansions the shell
does):

print "`date -d '-$(($(date +%d)-1)) days' +%Y-%m-%d`"
date: invalid date `-$(($(date +%d)-1)) days'

obviously, the double quotes inside the backquotes are not
interpreted as string delimiters by gnuplot, otherwise the
string would end in between.

FIRST_DAY=2009-11-01

set xrange from variable

2009-11-23T04:57:08Z

Hello everybody,

I'm still trying to make successfull use of variables in my gnuplot
script, so I'm asking how it would be possible to do a "set xrange"
using a variable.

I have following variables:

FIRST_DAY=`date -d "-$(($(date +%d)-1)) days" +%Y-%m-%d`
LAST_DAY=`date -d "+1 month -$(date +%d) days" +%Y-%m-%d`

What I need to achieve is to set xrange in between the above two values.
Today it should give:

set xrange = [2009-11-01:2009-11-30]

I tried with

set xrange = [FIRST_DAY:LAST_DAY]

but it doesn't work.

Any help will be appreciated!

Thanks,
Flavio Boniforti

Well, actually I have played a bit with setting variables inside gnuplot and trying to concatenate them.

I succeeded in concatenating *string* variables:

gnuplot> VAR='polti'.'-'.`date +%Y`
gnuplot> print VAR
polti-2009
gnuplot> VAR=VAR.'-'.`date +%m`
gnuplot> print VAR
polti-2009-11

I think playing with these sort of variable definitions, also will lead me to success... What do you think of this?

There are several approaches. The basic choice is between parametrizing
a canned gnuplot script from the outside using environment variables
(`echo $VARIABLE` style), and modifying the script on the fly (HERE
script or piping individual commands from another scripting language to
gnuplot).

2009-11-20T08:00:41Z

each plot needs it's own data:

This pattern is observed whether or not the final "e" line is present in

Re: rowstacked with 60 columns: key pushes graph off page

2009-11-20T07:54:02Z

increase the size of the postscript output:

set terminal postscript enhanced color size 80cm,29.7cm

I'm using gnuplot with "histogram rowstacked" to plot many columns from
a data file. The column titles are quite long too. But the key (legend)
is then too big for the page, and even pushes the graph off the page

Is there any generic way to just get everything to scale down enough to
fit on the page? I'm outputing to .ps, so I don't mind if people have to
zoom in to actually read things.

Here's my whole set of commands.

Histogram plots not working as inline data?

2009-11-20T05:40:46Z

I am having trouble getting a histogram plot to work.

As an experiment I tried the following which is approximately similar to
my script"

Take the histogram4.gnu script from demos.
Replace the "immigration.dat" file reference with "-" and copy the data
inline data from immigration.dat into the script, resulting in the
attached histograms4a.gnu.

The original script works fine. The script with the inline data
produces the following and a graph with only the first set plotted.
This pattern is observed whether or not the final "e" line is present in
the script. What is happening here and how may it be fixed?

Creating graphs from byte transfers and scheduling them

2009-11-20T00:47:22Z

Hello everybody.

I'm pretty new at gnuplot, but I already achieved my first result...
(see: http://yfrog.com/j8polti200911p )

Now, what I'm doing is to grab every night the total amount of traffic
being sent/received via SSH between my server and a couple of different
remote hosts. I achieved this via iptables, but I don't want to bother
you all... The result of this data collection is like:

2009-11-16 4296994550 155016994
2009-11-17 6458167774 228657538
2009-11-18 8776045950 424622670

The columns represent date, bytes received, bytes sent.

I now would like to schedule a daily update of the graph you can see at
the above URL, but also:

A) the graph should be generated *new* when the actual month is over
(I'd like to have different PNGs for each month);
B) it should be schedulable, but I don't know how to put or pass
variables to the plot script

Here the plot script I'm using:

set term png
set output 'polti-2009-11.png'
set timestamp 'Ultimo aggiornamento: %d.%m.%Y' top
set xdata time
set timefmt '%Y-%m-%d'
set xrange ['2009-11-01':'2009-11-30']
set xlabel 'Data'
set format x '%d.%m'
set ylabel 'Bytes'
set format y '%.0s %cb'
set title 'Traffico'
set key off
set boxwidth 0.8 relative
set style fill solid 1.0
plot '2009-11-213.200.254.141.dat' using 1:2 with boxes fs solid,\
'2009-11-213.200.254.141.dat' using 1:3 with boxes fs solid

Any help will be appreciated, thanks in advance!
