This is one method that I've found so far. It consists of splitting up the data in separate files, then using the mulitplot command to place the plot on top on one another. So there is a driver script, a file of commands, and files of data points. This is a demonstration with the terminal (very low resolution, but easily pastable):
Producing:
If this is the easiest (or only) method, then the real problem will be to separate the data points with a script to avoid error-prone manual data manipulation.
Perhaps someone will stop in to show us a better method ... cheers, drl
Hi, I am a beginner using UNIX, and was wondering how to use gnuplot from UNIX on my pc. I am connected remotely to my work's UNIX server using Secure Shell Client, and gnuplot won't open a new window when I use the plot command. How do I do this?
Moreover, is it possible to save things from the... (0 Replies)
I have a simple gnuplot question. I have a set of points (list of x,y,z values; irregularly spaced, i.e. no grid) that I want to plot. I want the plot to look like this:
- points in map view (no 3D view)
- color of each point should depend on its z-value.
- I want to define my own color scale

Hi,
I am trying to make a plot of an ASCII file using GNUplot, but I keep getting error msg:
for example plot filename.txt
It says that (.txt ) is not identified ... I tried to write it without the .txt part, but I also get the error msg.
Any idea why? :confused: (1 Reply)
Hi All,
Seems I have an xargs stdin problem that I don't understand.
I have a script (call it myscript.sh) that takes the names of one or more file(s) specified on the command line and creates a single gnuplot command file containing multiple records, one for each specified file. Each of... (9 Replies)
Hi,
I am trying to arrange my graphs with GNUPLOT. Although it looked like simple at the beginning, I could not figure out an answer for the following: I want to change the style of my data points (not the line, just exact data points) The terminal assigns first + and then x to them but what I...

PLOTCHANGELOG(1) General Commands Manual PLOTCHANGELOG(1)NAME
plotchangelog - graph debian changelogs
SYNOPSIS
plotchangelog [options] changelog ...
DESCRIPTION
plotchangelog is a tool to aid in visualizing a Debian changelog. The changelogs are graphed with gnuplot(1) , with the X axis of the graph
denoting time of release and the Y axis denoting the debian version number of the package. Each individual release of the package is repre-
sented by a point, and the points are color coded to indicate who released that version of the package. The upstream version number of the
package can also be labeled on the graph.
Alternatively, the Y axis can be configured to display the size of the changelog entry for each new version. Or it can be configured to
display approximately how many bugs were fixed for each new version.
Note that if the package is a debian-specific package, the entire package version will be used for the Y axis. This does not always work
perfectly.
READING THE GRAPH
The general outline of a package's graph is typically a series of peaks, starting at 1, going up to n, and then returning abruptly to 1.
The higher the peaks, the more releases the maintainer made between new upstream versions of the package. If a package is debian-only, it's
graph will just grow upwards without ever falling (although a bug in this program may cause it to fall sometimes, if the version number
goes from say, 0.9 to say, 0.10 - this is interpreted wrong..)
If the graph dips below 1, someone made a NMU of the package and upgraded it to a new upstream version, thus setting the debian version to
0. NMU's in general appear as fractional points like 1.1, 2.1, etc. A NMU can also be easily detected by looking at the points that repre-
sent which maintainer uploaded the package -- a solitary point of a different type than the points before and after it is typically a NMU.
It's also easy to tell by looking at the points when a package changes maintainers.
OPTIONS -l, --linecount
Instead of using the debian version number as the Y axis, use the number of lines in the changelog entry for each version. Cannot
be used together with --bugcount.
-b, --bugcount
Instead of using the debian version number as the Y axis, use the number of bugs that were closed by each changelog entry. Note that
this number is obtained by searching for "#dddd" in the changelog, and so it may be inaccurate. Cannot be used together with
--linecount.
-c, --cumulative
When used together with either --bugcount or --linecount, graphs the cumulative count rather than the count in each individual
changelog entry.
-v, --no-version
Do not show upstream version labels. Useful if the graph gets too crowded.
-m, --no-maint
Do not differentiate between different maintainers of the package.
-s file, --save=file
Save the graph to file in postscript format instead of immediately displaying it.
-u, --urgency
Use larger points when displaying higher-urgency package uploads.
--verbose
Output the gnuplot script that is fed into gnuplot (for debugging purposes).
-gcommands, --gnuplot=commands
This allows you to insert gnuplot(1) commands into the gnuplot script that is used to generate the graph. The commands are placed
after all initialization but before the final plot command. This can be used to override the default look provided by this program
in arbitrary ways. You can also use things like "set terminal png color" to change the output file type, which is useful in conjunc-
tion with the -s option.
--help Show a usage summary.
--version
Display version, author and copyright information.
--noconf, --no-conf
Do not read any configuration files (see below).
changelog ...
The changelog files to graph. If multiple files are specified they will all be display on the same graph. The files may be com-
pressed with gzip. Any text in them that is not in Debian changelog format will be ignored.
CONFIGURATION VARIABLES
The two configuration files /etc/devscripts.conf and ~/.devscripts are sourced by a shell in that order to set configuration variables.
The --no-conf option can be used to prevent reading these files. Environment variable settings are ignored when these configuration files
are read. The currently recognised variables are:
PLOTCHANGELOG_OPTIONS
This is a space-separated list of options to always use, for example -l -b. Do not include -g or --gnuplot among this list as it
may be ignored; see the next variable instead.
PLOTCHANGELOG_GNUPLOT
These are gnuplot commands which will be prepended to any such commands given on the command line.
SEE ALSO devscripts.conf(5).
