org-babel and gnuplot

[-- Attachment #1.1: Type: text/plain, Size: 783 bytes --]

Hello,

I am attempting to generate a simple chart from gnuplot using the source of
an org-table.  When I execute the gnuplot src block I get the message
"Source block produced no output".  Does anyone have any suggestions as to
what might be the cause?  I have included a sample of what I am trying to
run:

#+tblname: sessions
| Date       |  Time | Distance |
|------------+-------+----------|
| 09/02/2010 | 15:13 |      2.5 |
| 09/01/2010 | 14:00 |      2.4 |

#+begin_src gnuplot :var data=sessions
  :file org-running.png :exports both
  set title "Running Stats"
  set auto x
  set style data histogram
  set style fill solid border -1
  set boxwidth .9
  set xlabel "Date"
  set ylabel "Time"
  plot "$data" using 1:2:3 notitle
#+end_src

Hi Nick,

Maybe two things off hand (booted into OS X right now where I can't try your
code..)

1) try using straight gnuplot without going through org to verify your
commands. This helps make sure that the syntax isn't producing errors.
Another way to check this out sometimes is to C-c C-c on the code block, run
the code, and then C-x b to the *gnuplot buffer to view any error messages.
Those might prove helpful.

2) try changing your plot line to: plot data using 1:2:3 notitle

I think I ran into an issue using "$data" even though it's the gnuplot
syntax. I found org examples on the mailing list where just "data" was used
instead (no quotes) and that worked.


John

P.S. Are you trying to make a 3D graph? plot using 1:2:3 will yield a 3D
graph and you didn't mention a z-axis label so I'm wondering if that's
really what you want? You may want to split this into two graphs to have
date vs. time and date vs. distance? Or date vs. distance/time (speed)?

P.P.S Or perhaps judging by the boxwidth option you want the width of the
bars in the graph to represent the miles run? In that case you want 'plot
data using 1:2:3 with boxes notitle' I think.

Hi John,

I would actually like to plot different lines per distance, each
that correlate to a date and elapsed-time (x and y axis respectively).  I
get an error with the :file notation, though I read that in a sample babel
gnuplot example for generating graphs of commit history on the org-mode git
repository.  I tried to reference the variable data without the quotes and $
sign without any success.  I will continue to fiddle with it, I am new to
gnuplot.

AFAIK, you can't break source code header argument lines across
multiple lines.  Is that how you actually have it in your
org file?

Erik,

That was the issue, the :file reference needed to be on the line above.
 Thanks.

That's great! I actually figured that was from pasting it. A lot of pasted
examples come in a bit jumbled.

Glad you're on your way!

Nick,


This got me curious to see the output. I tried to generate it on my computer
and get this in the *gnuplot* buffer after running the code:

-----
gnuplot> plot data using 1:2:3 notitle
                               ^
         warning: Skipping data file with no valid points
                                      ^
         x range is invalid
-----

This is working for you, though?

#+tblname: sessions
| Date       |  Time | Distance |
|------------+-------+----------|
| 09/02/2010 | 15:13 |      2.5 |
| 09/01/2010 | 14:00 |      2.4 |

#+begin_src gnuplot :var data=sessions :file org-running.png :exports both
  set title "Running Stats"
  set auto x
  set style data histogram
  set style fill solid border -1
  set boxwidth .9
  set xlabel "Date"
  set ylabel "Time"
  plot data using 1:2:3 notitle
#+end_src

John,

I am reworking the gnuplot script, it is not done at this point, but this is
what I currently have:

#+begin_src gnuplot :var data=sessions :file org-running.png :exports both
  set title "Running Stats"
  set xtics nomirror rotate by -45
  set key noenhanced
  set style data linespoints
  plot "$data" using 2:xtic(1) title columnheader(1), \
  for [i=2:3] '' using i title columnheader(i)
#+end_src

Re: org-babel and gnuplot

Nick,

How about this?? Just fiddled around a little and wonder what you think.
There might be a better way, but essentially, I've done the following:

- Left y-axis = distance
- Right y-axis = time
- I couldn't get the xtic(1) option to work, so I replaced things with what
I've found to work x:y:xticlabels(col#)
- Beefed up the points to make them a little easier to see
- Used your data to "calibrate" your speed
--- The left y-axis is from 9-21min
--- The right y-axis is from 1.5min - 3.5min
--- This means the axes are 'calibrated' to 10mph

What does the "calibration" do? It means that at a quick glance you can see
your speed based on a target rate you set:
- if speed/distance are on top of each other, you're right at your target
- if speed (green) is higher than distance (red), you were faster than your
target
- if speed (green) is lower than distance (red), you were slower than your
target

Resetting your target is as easy as changing (in the code below):
- Time: yrange [y1:y2]
- Distance: y2range [y3:y4]

All you have to do is make sure that y3/y1 = y4/y2 = target speed

Also, remove the references to L/R and Red/Green if you'd like from the
labels. I just tried to make the labels as easy as possible to follow so
that no matter where you looked for a reference you would be forced to see
what color/axis matched what value.

I attached a sample graph. Sorry if I overstepped my bounds -- I realize
it's *your* workout tracker. Take what you like and ditch the rest. I wanted
to know how to do two different y axes anyway so it helped me learn. Code is
here:

------------------- gnuplot code -----------------------

#+tblname: sessions
| Date        | ID |  Time | Distance |
|-------------+----+-------+----------|
| 9/1/2010    |  1 | 14:00 |      2.4 |
| 9/2/2010    |  2 | 15:13 |      2.5 |
| 9/10/2010   |  3 | 13:45 |      2.3 |
| 9/11        |  4 | 12:20 |      2.0 |
| Spd > 10mph |  5 | 16:35 |      2.8 |
| Spd = 10mph |  6 |    10 |    1.666 |
| Spd < 10mph |  7 |    20 |      2.8 |

#+begin_src gnuplot :var data=sessions :file org-running.png :exports both
  reset
  set title "Running Stats"
  set size ratio square

  set xlabel "Date"
  set xtics nomirror rotate by -45

  set yrange [9:21]
  set ylabel "Time (min) -- Red"
  set ytics nomirror

  set y2range [1.5:3.5]
  set y2label "Distance (mi) -- Green"
  set y2tics 0,0.5,3.5

  set style data points
  plot data u 2:3:xticlabels(1) axis x1y1 lw 3 title 'Time (L axis)', \
       data u 2:4 axis x2y2 lw 3 title 'Distance (R axis)'
#+end_src

------------------- end gnuplot code ---------------------


Best regards,
John

org-babel and gnuplot

[Carlos Russo]

Hi

I was trying a  gnuplot source block, and was stricken by "No org-babel-execute function for gnuplot!" when I tried to execute the block.
I made sure the variable org-babel-load-languages contained (gnuplot . t) , so I was quite puzzled.

It turns out that I needed to explicitly add 
(require 'ob-gnuplot)
to my .emacs file.

According to the documentation, this line should not be needed for org-mode 8.03 (my current version).
It this a bug in the documentation?

Cheers,
Carlos

There are instructions for enabling language in the following page of
