Of course you do.  The line1Width resource specifies the default 
linewidth.  The actual linewidth is the default multiplied by the 
argument of 'lw'.

They're called "borders", in gnuplot, and yes, they can be removed:

	unset border ; unset xytics ; unset ztics

	set style increment user
	set style line 50 lt 3 lc rgb 'orange'
	set style line 51 lt 2 lc rgb 'cyan'
	set hidden3d
	splot x*sin(y) with lines 50

Interestingly, this changes behaviour if you replace the '50' by it's 
should-be equivalent 'lt 50' or 'ls 50'

[Gnuplot-info] still issues with building latest gnuplot version on opensuse

[Dieter J. <die...@t-...>]

Dear listmembers,
dear Mr. Broeker,

I yelled "ok" too early. It is not ok.

The build process runs ok.

However:
The file /usr/share/X11/app-defaults/Gnuplot is not found due to the fact that 
the path to the app-defaults directory is hard-coded in src/gplt_x11.c

It cannot be handed over via src/Makefile.am because the commandline define is 
being overridden in gplt_x11.c

The minimum change required is to put a
#ifndef AppDefDir
#define AppDefDir="/usr/lib/X11/app-defaults"
#endif /* AppDefDir */

into gplt_x11.c.

However, IMHO you should not be forced to double-specify the very same 
parameter: in src/Makefile.am as -DAppDefDir=<anyplace/anywhere> _and_ in

make appdefaultdir=<anyplace/anywhere> install.

Moreover from a convention standpoint I would suggest changing the name

#define AppDefDir 

into 

#define APPDEFAULTDIR

for consistency reasons.

Migth be a good idea to put this into config.h anyway and make Makefile.am 
aware of what has been defined - if it has been defined. The way it is now is 
not what I would consider consistent.

Thank you for looking into this,
take care

[Gnuplot-info] Gnuplot configuration issue

[Dieter J. <die...@t-...>]

Dear listmembers,
dear Mr. Broeker,
when specifying a linewidth in <appdefaultdir>/Gnuplot,

say

gnuplot*line1Width:  2

and plot something in gnuplot, say

plot x*x w l

you will get the same result (from a linewidth standpoint) as if you say

plot x*x w l lw 1

see 1 != 2. Is that intended to be this way?

plot x*x w l lw 2 is much thicker and corresponds to a <appdefaultdir>/Gnuplot 
entry of

gnuplot*line1Width: 3

This seems inconsistent IMHO. Thank you for looking into this,
take care

[Gnuplot-info] Is it possible to remove the axis in a 3d plot? (+bonus question)

[micmac <jul...@da...>]

Hi, I am completely lost with the use of splot:
Is it possible to remove the axis completely in a 3D plot with splot?



PS: I have a bonus question, when we plot a surface with the hidden3d option
on, tere are two colors, one for the top, and one for the bottom of the
surface. Is it possible to define these two colors seperately (for now, I
just use lt 1 for example whixh sets the two colors but not independently)

thanks very much!!!!!

BTW, that means it was not a legend (or title) of the colorbox at all. 
It was related to the actual plot.

[Gnuplot-info] how to suppress colorbox's legend and single isoline warning

[H.S. <hs....@gm...>]

Hello,

On Gnuplot 4.2, I am plotting some data points in different colors. Let 
the data file be:
########## deleteme.dat ############
0.1417    0.0687          1
0.6740    0.1184          3
0.1555    0.7588          2
0.8975    0.7091          4
####################################

where the last column indicates the color of the points. (The color just 
needs to be different for each different value in the third column. It 
does not really matter what exactly that color is.)

Then the following commands give me the result:
gnuplot> set pm3d
gnuplot> set view map
gnuplot> splot "deleteme.dat" with points palette pt 9
   Warning: Single isoline (scan) is not enough for a pm3d plot.
            Hint: Missing blank lines in the data file? See 'help pm3d' 
and FAQ.


I have two questions here:

1. The output plot has a legend (if that is what it is called) just 
above (or beside) the colorbox with the string:
"deleteme.dat" followed by three little points. It appears that the 
three points give the three colors in the palette range: lowest, middle 
and highest. How do I suppress this legend? The example above just plots 
a data file. But in reality, I am plotting from a number of data files 
using bash commands to generate the data. So I get the whole command as 
the legend string and it looks quite ugly.

2. What about the warning I get above? How can I get rid of it?

thanks,
->HS

[Thomas S. <t.s...@fz...>]

'plot ... using 1 ...'
numbers the data points starting from zero, your plot borders are [1:8], so
the first data point isn't plotted.

either change the first line in your datafile or
'plot ... using ($0+1):1 ...'

Re: [Gnuplot-info] issue with building latest gnuplot version on opensuse

[Dieter J. <die...@t-...>]

Dear listmembers,
dear Mr. Broeker,
ok - specifying
appdefaultdir=/where/ever
does the trick. The opensuse developers had had specified  
xresourcedir=/where/ever
so far, this did not work for 4.2.3 but did work for 4.2.2. 
That was the reason why I stumbled over the Makefile.am specification in 
share/ as it was changed from 4.2.2 to 4.2.3.
I had guessed that this was related to the AppDefDir define, may easily be 
that I had had been wrong in this regard.
Anyway, specifying appdefaultdir instead of xresourcedir does work.

Thanks for helping here,
take care

Hello,

I have it working to some extent using splot and map view. The main

set pm3d
set palette rgb 33,13,10
set view map
set cbrange [1:4]
ssplot "3cols.dat" with points palette pt 9


However, I am still trying to see how to do this using the 'plot' 
command. Could you give me an example how to plot the following data 
such that the colors are determined by the 3-rd column using 'plot' 
command? Or is not possible with this command?
######### 3cols.dat #########
0.2846    0.1857          1
0.8283    0.1330          2
0.3306    0.8348          3
0.7961    0.7968          4

Re: [Gnuplot-info] plotting each point in different color and color palettes or color map

You want to re-read 'help plot with' and pay particular attention to the 
'palette' option.

[Gnuplot-info] first line of data file being missed

[H.S. <hs....@gm...>]

Hello,

Here is a datafile I am trying to plot:
############ delme.lout ##############
1
8
   1
   2
   3
   4
########### delme.lout ##############

The first two lines gives the x-range, here it is 1:8

The remaining lines give the data to be plotted. I extract those lines 
using the command:
$> tail -n +3 delme.lout
   1
   2
   3
   4

So, the above command gives the data at the output. So far so good.


Keeping this in mind, here are the commands I use in gnuplot to plot 
this data (the x-range is made up from the top two lines):
gnuplot> set style line 1 lt 1 lw 1 pt 5 ps 1.5
gnuplot> plot ["`head -n 1 delme.lout`":"`more +2 \
  delme.lout | head -n 1`"] \
  "< tail -n +3 delme.lout" using 1 title 'Data Points' ls 1


The problem is, it appears that I am missing the first data point in the 
  plot. What am I doing wrong?

[Gnuplot-info] plotting each point in different color and color palettes or color map

[H.S. <hs....@gm...>]

Hello,

I have a number of groups of 2-D points which I want to plot such that 
each group's points (the points are already labeled based on which group 
they belong to) are plotted in a different color.

So, if I have N groups, I want to plot all the points on to the same 
graph, but there are going to be N colors for the plotting (one for each 
group). N may change in different experiments.

So here is what I am looking to do:

1. How do I construct a 'color palette' or 'color map' so that, e.g., 
group 1 is of red color and as group label increases the color gradually 
changes to blue (going through the rainbow colors). In this example, if 
I have N groups, I would like to have N different colors in the range of 
red to blue (something identical to colormap in Matlab).

2. Find out how to specify the color of each point as I plot it. If I 
can find out the 3-tuples of N colors in step 1, can I specify that 
3-tuple as a color for each point?

Thanks,
->HS
