In the /demo directory there is s demo called finance.dem which makes
use of multiplot and titles. Perhaps that might help?

   I found the solution in

     http://www.gnuplotting.org/plotting-single-points/

   So, for those who are interested, my line reads finally.

   plot \
   'file' using ((strcol(2) eq 'X' && $3 == 1) ? $4 / 1000000: NaN)
: $0 ti 'Group X (9)' w points, \
   "<echo '16'" using 1:$0 notitle with points;

Best regards.

Re: [Gnuplot-info] Question about clustered histograms

[Brian O. <bos...@ve...>]

Thomas,

Right. Tried a number of variations of "for", none of them worked. Now I'm using the "using 2:xtic(1) title col …" syntax, similar to what you suggested, and it works fine.

Thanks again,

Brian O.

these are the keys.

to switch them off, use 'unset key' or an empty 'title'
option in the 'plot' command.

if you use only one column for the histogram, then there
is nothing to cluster.

> What am I doing incorrectly?

maybe it would be better not to use the 'for' loop, instead
you could use:

plot 'tmp_data_file' using 2:xticlabels(1) title 'dataset 1', \
'' using 3 title 'dataset 2'

[Gnuplot-info] Question about clustered histograms

[Brian O. <bos...@ve...>]

Plotters,

The plotting is just not working, though I think I'm following the example code in the manual (page 51).

Here's the script:

set terminal png 
set output 'histograms.png'
set style fill solid 1.00 border lt -1
set style data histograms
set style histogram clustered gap 2
set xtics border rotate by -45
plot for [COL=2:3] 'tmp_data_file' using COL:xticlabels(1)

And my data looks like this:

e-02	2	4
e-03	11	33
e-04	33	2

The clusters of bars and X labels are made correctly but lines like:

'tmp_data_file' using COL:xticlabels(1)

are inserted at the top of the image, where the keys should be.

If I use "[COL=2:3:2]" instead then only a single bar is created, rather than a cluster of 2 bars.

What am I doing incorrectly?

Thank you,

Brian O.

Hi Elias.

I know what's happening. It was actually clear from your previous email,
but I didn't look closely enough. There're several flavors of the
libwx...-dev packages in Debian. You only have 'libwxbase2.8-dev'
installed, with has only the non-ui stuff in it, hence you're seeing
problems. Install 'libwxgtk2.8-dev' as well, and your issues should go
away. Let me know if something is still broken.

There IS a bug in gnuplot here, since ./configure shouldn't have
succeeded in this case. I'll look at fixing it.

[Gnuplot-info] SVG with dashed lines results in first line not being dashed

[Michael B. <mj...@gm...>]

Hi, I have the following gnuplot file:

set terminal svg size 800,600 dashed linewidth 2
set output
set multiplot
plot cos(x), \
     sin(x)

The SVG it outputs results in the first path being defined as <path
 d='M716.2,34.7 L758.4,34.7... and the second path being defines as <path
stroke-dasharray=' 5,8'  d='M716.2,52.7 L758.4,52.7... Note that the first
path is not dashed, while the second path is.

Why is the first line not dashed? Am I missing something in the manual? I
thought specifying "dashed" when I set the terminal would make all the
lines dashed, by default.

If it helps, gnuplot --version yeilds:
gnuplot 4.6 patchlevel 3

And I'm running OS X 10.8.4 (with gnuplot being installed from brew).

Thanks for your help,

Michael

OK. Thanks for that.

What's supposed to happen is that ./configure should run 'wx-config --cxxflags'.
That should return a string containing -D__WXGTK__, and this string should end
up in the CXXFLAGS. So you can check for that. If you send the exact compilation
command that is failing and the config.log, I can check for you. Also, post what
''wx-config --cxxflags' returns.

Hi
I have a data file which looks like

What I want to do is to plot the second column if the third column is 'M'. Is it possible to to do that with a magic command (piping plt with grep) inside the gnuplot? Or I have to do a preprocess on the data file and extract all lines with 'M' value to another file and then plot the new file?
