Hello - I'm new in gnuplot. I wrote a script which reads single lines with the "every" option. This works well, but I have two questions: 1) I'd love to have the value which is written in column 1 (which is a time in my case) as the legend (key). Is this possible? 2) I have several xy-pairs in a line. I plot them with "myfile.txt" every ::1::1 using 3:2 with imp,\ "" every ::1::1 using 6:5 with imp notitle,\ "" every ::1::1 using 9:8 with imp notitle,\ and so on. Can I change the colors in a way that the first xy-pair (using 3:2 in the example above) is in red colour, and then the color circle is crossed so that the last value is blue? (There are different numbers of pairs; sometimes 6 or 12 or whatever. In each case the first xy-value should be red and the last blue.) Thanks for any help. Best regards - joachim |

Thanks a lot for your help. The palette is working now. Unfortunately I have now a large color palette on the right side of my plot. How can I get rid of it? And until now I couldn't find a way to show my first column as a label. Something like 'set label $1' - but what is the correct syntax for it? joachim Am 11.05.2009 um 17:56 schrieb Thomas Sefzick: > > define a palette which goes from 'red' to 'blue, see > http://www.gnuplot.info/docs/node215.html > > and then plot with explicit line colors > > plot "myfile.txt" every ::1::1 using 3:2 with imp linecolor palette > frac > 0.0, \ > "" every ::1::1 using 6:5 with imp notitle palette frac 0.1, \ > "" every ::1::1 using 9:8 with imp notitle palette frac 0.2, \ > ... > > for more information, see > http://www.gnuplot.info/docs/node62.html > > > joachim heintz wrote: >> >> Hello - >> >> I'm new in gnuplot.

Thanks. 'unset colorbox' does its job. But with you suggestion
regarding getting a data value as a key I get the following:
gnuplot> plot "/Joachim/ShellSkripte/00gnuplot/Ganze1_12pms.txt"
every ::1::1 using (my_key=sprintf("%d",$1),0/0):(0/0) notitle, "/
Joachim/ShellSkripte/00gnuplot/Ganze1_12pms.txt" every ::a::a using
3:2 with imp title my_key linecolor palette frac 0, "/Joachim/
ShellSkripte/00gnuplot/Ganze1_12pms.txt" every ::a::a using 6:5 with
imp title my_key linecolor palette frac .333333, "/Joachim/
ShellSkripte/00gnuplot/Ganze1_12pms.txt" every ::a::a using 9:8 with
imp title my_key linecolor palette frac .666666
^
"/tmp/gnupl005512.txt", line 7: ')' expected
(no newlines in the terminal output; just in this email)
Am I doing something wrong? No idea which ')' I am missing.

the caret is below the 1st 'y' of the 'title my_key', isn't it?
i can reproduce this behaviour here with gnuplot 4.2.
sorry, i forgot to mention, you need gnuplot 4.3-cvs. version
4.2 doesn't have those the operators '=' and ',' in expression
syntax. you need to upgrade to version 4.3.

I'm not sure how complicated it will be to upgrade to 4.3-cvs. I'm on
OSX and had some difficulties to install gnuplot. Compiling from
sources gave some errors I didn't understand, so I went to the
darwinports. This worked, but I'm not sure if I can install 4.3 via
Darwinports.
For the moment it would be sufficient to print my first column in the
Terminal window. Can I do this with gnuplot 4.2? I tried 'print $1'
but this doesn't work.
Thanks -

you could read in the 1st column on a per-line basis
using unix (do these exist on a mac?) commands:
s=system('head -n 1 datafilename | tail -n 1 | awk "{print \$1}"')
or
s=system('head -n 2 datafilename | tail -n 1 | awk "{print \$1}"')
you read up to the line you want to get the data from (head),
then you take the last line only (tail), and extract the 1st value (awk).
then you may use the variable 's' for setting a label
set label 1 s at .....
or setting the plot key
plot 'datafilename' using ... title s ...

Yes, no problems with Unix commands on OSX. It was a bit complicated,
because I have the line number as a variable which is changing in a
reread loop after pausing a while. I got this with (the variable "a"
is the line number)
command = sprintf("head -n %d $myfile | awk '{print $1}'", a)
zeit = system(command)
Now I could say
print zeit
and the first column of the line is printed in the Terminal window.
When I tried to see this in the plot window with
set label 1 zeit at ...
or
plot ... title zeit
it prints indeed, but it doesn't overwrite the previous print when the
plot is reread. Instead it prints the values one under each other. I
don't know if this can be achieved?
Thanks again -
