Hello list,
I am trying to plot some candlesticks through org-plot/gnuplot, but I
fail.
It seems that org-plot/gnuplot supports a list of numbers in deps, i.e.,
deps:(2 3 4) and then creates a string of the form:
'test.dat' using X with lines
where X is first 2 then 3 and finally 4 for deps:(2 3 4)
To plot candlesticks though, gnuplot expects a line of the form:
'test'.dat' using 1:3:2:6:5:xticlabels(7) with candlesticks whiskerbars
I thought that maybe setting deps to ("1:3:2:6:5") could give me the
result I wanted, but I was wrong.
I have traced the problem to be in org-plot/gnuplot-script, specifically
in the following code segment:
--8<---------------cut here---------------start------------->8---
(2d (dotimes (col num-cols)
(unless (and (eq type '2d)
(or (and ind (equal (1+ col) ind))
(and deps (not (member (1+ col) deps)))))
(setf plot-lines
(cons
(format plot-str data-file
(or (and ind (> ind 0)
(not text-ind)
(format "%d:" ind)) "")
(1+ col)
(if text-ind (format ":xticlabel(%d)" ind) "")
with
(or (nth col col-labels) (format "%d" (1+ col))))
plot-lines)))))
--8<---------------cut here---------------end--------------->8---
This code-segment essentially goes through the columns in the data file
and checks for each of them if it is contained in `deps`, if so it
proceeds with creating a line of the form:
'test.dat' using X...
I believe an easy fix would be to unconditionally go through deps and
create a line of the form:
'test.dat' using X... where X is the corresponding element of deps.
I tried to hack it, but didn't have much success, any help is welcome.
Kind regards,
Foivos

Org plot is there for quick and easy plotting. I would recommend using
babel with gnuplot source blocks. You can easily pass tables as data,
and configure your plot as you wish. Unfortunately I have not done this
recently, so I don't have any simple examples handy, but I'm sure there
are plenty on Worg.
Hope this helps,

I see what you mean, but I believe something like
--8<---------------cut here---------------start------------->8---
#+PLOT: ind:1 deps:("1:4:3:7:6") with:candlesticks
|------------+-----------+------+------+--------+------+------|
| # Variable | mean | min | q1 | median | q3 | max |
|------------+-----------+------+------+--------+------+------|
| 1 | 2166 | 2166 | 2166 | 2166 | 2166 | 2166 |
| 15 | 2166.6666 | 2166 | 2166 | 2167 | 2167 | 2168 |
| 255 | 2167.1803 | 2166 | 2167 | 2167 | 2168 | 2169 |
| 271 | 2247.3874 | 2242 | 2246 | 2247 | 2249 | 2252 |
|------------+-----------+------+------+--------+------+------|
--8<---------------cut here---------------end--------------->8---
is still pretty simple and yet so powerful.

It sure does! I'll have a look into it, thanks.
