Re: [Gnuplot-info] Graph coincides with axes and disappears

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

you could do a dummy plot to determine the yrange
and then extend this range before doing the real
plot, e.g.:

ts.dat:
1 2
2 1
3 4
4 4
5 3

ts.plt:
reset
factor=0.05
set term push
set term dumb
plot 'ts.dat' using 1:2 with linespoints
temp=factor*(GPVAL_Y_MAX-GPVAL_Y_MIN)
set yrange [GPVAL_Y_MIN-temp:GPVAL_Y_MAX+temp]
set term pop
replot

gnuplot> load 'ts.plt'

Re: [Gnuplot-info] several plot windows?

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

depends on the terminal you are using, some support
several plot windows:

[Gnuplot-info] several plot windows?

[jody <jod...@gm...>]

Hi
Is it possible to have gnuplot open several plot windows at once?
If yes, how?

Thank You

[Gnuplot-info] Graph coincides with axes and disappears

[Torquil M. S. <to...@gm...>]

Hi!

I use autoscale for the range of the axes, but portions of my graphs 
often disappear behind the top or bottom horisontal axes, especially 
when I plot integer valued functions.

Is it possible to specify that the autoscale function should add a small 
amount, e.g. 5%, so that the whole graph is visible? I don't want the 
graph to reach the top or bottom horisontal axes, but nor do I want to 
specify the axis range manually.

Any ideas? I'm using a reasonably new CVS version of gnuplot.

Thanks,
Torquil Sørensen

Re: [Gnuplot-info] error with pm3d

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

it means that your file containes 1e6 data points but gnuplot
found out that the length of a so-called scanline (number of
points in a row) is 895.
and 1e6 isn't an integer multiple of 895.

Re: [Gnuplot-info] ugly data-point rounding error

[some_guy <som...@ya...>]

You are right. As I'm using gnuplot 4.2 patchlevel 4, the effect is indeed
smaller. SVG_SCALE=10 and all data-points are rounded to a tenth of a pixel.

This is much more satisfying, but errors are still visible. Could we set
SVG_SCALE to 100 or 1000 ?

Re: [Gnuplot-info] arrow quality with gnuplot?

Hi Julien,
here you go with an example I am using. IMHO there is not a single bad thing 
to  be said about the arrow quality. I am using gnuplot 4.2.5 on linux  -  
just take a look on the example!

The only issue you might be confronted with is the fact that the 4.2 series of 
"regular" gnuplot does not support umlauts and similar characters for the utf8 
terminal - hence, depending on your operating system, your results may vary.

The way of placing the axis arrows here is the best I can suggest. 
Unfortunately gnuplot does not allow to set aligned arrows with "regular" x- 
and y-labels hence you have to help yourself.

Hope this helps,
pdf attached - do not know whether it can pass through into the mailing list.
Take care

[Gnuplot-info] Using plot in a user defined function

[Armin A. <aar...@nd...>]

Hi,

I'm trying to define a 'function' that essentially is a plot command with
the filename as parameter. Please see the example at the end. I want to do
this to save myself from repeatedly having to use the same plot command (
I'm using it in a multiplot that plots data from several files into one
plot).
Anyhow, the way I'm trying it doesn't seem to work and I couldn't figure out
how to do it properly.

Thanks for your help.
Armin


Sample code:
scatterplot(f) = plot f using (column(1)-1.5*xsep):2 pt ptype lc clr1 ti '0
min',\
	'' using (column(1)-0.5*xsep):14 pt ptype lc clr2 ti '30 min',\
	'' using (column(1)+0.5*xsep):25 pt ptype  lc clr3 ti '60 min',\
	'' using (column(1)+1.5*xsep):72 pt ptype  lc clr4 ti ' 180 min'

later in the script:
scatterplot('P8-00003.csv')

Re: [Gnuplot-info] ugly data-point rounding error

don't know with which version of gnuplot these plots were

i'm not able to reproduce this poor quality with
gnuplot 4.0, 4.2.5 and 4.3-cvs.

[Gnuplot-info] ugly data-point rounding error

[Ryan D. <som...@ya...>]

Hi,

I realized some strange jiggling of plotlines in many
svg-gnuplot-graphics. Especially when a plot is supposed to be precise
and many datapoints are used, the problem gets worse.

Seeking
for the bug in the sourcecode, it turned out the problem is that every
datapoint to be drawn is handed over as an integer, e.g.

TERM_PUBLIC void SVG_vector (unsigned int x, unsigned int y) .

In
case of the standard-settings SVG_SCALE=1 , this means, that every
point is binned to integer-pixelvalues, rendering the whole sense of
vector-graphics useless.

Some examples where the problem is directly visible:
http://commons.wikimedia.org/wiki/File:Normal_distribution_cdf.svg
http://commons.wikimedia.org/wiki/File:Soliton_2nd_order.svg (see the grid on the ground which is supposed to be
 flat)
http://commons.wikimedia.org/wiki/File:Arcsin_plot.svg

if you don't see what I mean, take a look at the 2000px versions. Many graphics of this kind can be found on the internet.


Since
it's not a problem concerning only svg-export but a flaw rooting deep
inside gnuplot, i cant't correct it by myself. Gnuplot is used in many
scientific applications and I'm absolutely convinced, that treating
data-points as float values is the only reasonable choice. Those
terminals who only support raster-images can round the values later on,
and even they can take advantage of precisely located data-samples. As
a user, I don't know how to solve it, so I hope you can fix this in the
sourcecode. Floating-point output to svg-files with at least 3 digits
precision seems essential.

thanks in advance!



btw: did you notice inkscape's inability to interpret the "color"-attributes in gnuplot-created svg-graphics? maybe it helps to
 assign stroke- and fill-colors directly.

Hi,

I use gnuplot since some time, and one thing I miss is the  ability to plot
thick lines other than solid with the Windows terminal (so convenient for

did somebody found an alternative, and do you know if this a feature
requested by many people?

[Gnuplot-info] to change color codes in postscript file

[balaji n. <bal...@ho...>]

Hi All,
           I have drawn multiplot using gnuplot ver4.0 with terminal postscript. I have more than 35 lines which are drawn as smooth csplines. I want to change color of these smooth csplines. How can I edit the postscript file?(its not clear in ps_file.doc). I tried even with png but I can't change the font in it. For colors in png, I changed with hex color codes. Is it possible to give hex color codes in postscript?

Re: [Gnuplot-info] hidden3d: hide surface with higher z value when splotting multiple surfaces from datafile

[delete000 <jua...@ho...>]

hello,

thanks for your help Hans-Bernhard Bröker-2. with your help i can now make
the plot i wanted. it would look much better though if i could at least
color the surfaces (solid color, no contour needed) and i think i can't do
that without using pm3d. so i guess i'll have to make a multiplot and plot
each surface on its own.

thanks again,
Stefanos

Re: [Gnuplot-info] Print-outputs to plot or ps-file

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

set label sprintf("%f",f(10))

have a look at:

[Gnuplot-info] Degree Symbol in pdf Terminal

[berndklaus <ol...@we...>]

Hello everyone,
How do I use the degree circle ° in the pdf terminal?
The following code does not work. Can anyone help?
Thanks. 
set term pdf enhanced color fsize 8 size 13cm,5cm
set label 9 "{/Symbol F}_1}=78{/Symbol \360}" font ",5" at graph 0.29, 0.4 ,
0.3 front textcolor rgb "black"

No they're not.  At least the real hidden3d mode quite definitely 
doesn't make such silly mistakes.

	set hidden3d
	splot 5, 4, 3, 2, 1

definitely doesn't have the surface at z=1 covering the one at z=5.

I wouldn't extend similar warranties to pm3d's same-named option, 
though.   Particularly not in older versions of gnuplot.

Not generally.  Nor would that make terribly much sense.  Surfaces must 
be ordered by distance to the view (i.e. the axis pointing out of the 
display plane), not the data z value.  Remember that you can rotate the 
view such that lower z's are closer to you than higher ones.

[Gnuplot-info] hidden3d: hide surface with higher z value when splotting multiple surfaces from datafile

[delete000 <jua...@ho...>]

Hello,

I'm trying to plot 5 surfaces in the same plot:

splot 'data.dat' u 1:2:5 w l,'data.dat' u 1:2:6 w l, 'data.dat' u 1:2:7 w
l,'data.dat' u 1:2:8 w l,'data.dat' u 1:2:9 w l

The problem is that when using hidden3d or pm3d-hidden3d, the surfaces are
ordered depending on which one is plotted first, so in the above example
"'data.dat' u 1:2:5 w l" covers "'data.dat' u 1:2:6 w l" which covers
"'data.dat' u 1:2:7 w l" and so on. Is it possible to order surfaces
depending on their z value at each point, so that if a surface falls beneath
another one at some point, only the highest one is visible at that point?

Thanks in advance,
Stefanos
