I refreshed today 7.01trans and noticed I couldn't get my gnuplots to
plot anymore: data from a table within the org file is no longer
digested nicely by gnuplot.
To test, I used the snippet below from the worg
http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-gnuplot.php:
** Data Table Plot
Plotting data points from a table could look like this:
#+tblname: basic-plot
| x | y1 | y2 |
|-----+------------+------------|
| 0.1 | 0.425 | 0.375 |

Exporting or executing the gnuplot piece, Gnuplot (Gnuplot 4.4 patch

No data in plot
So of course no basic-plot.png is created....
As far as I know, my gnuplots were happy sometime within the past week
refreshing org-mode from git basically daily...

I copied and pasted your exact table and code from the email and was able to generate the plot. The error is quite odd. It almost makes me wonder if something is different about how gnuplot is receiving the data. Like a syntax error or something. I would say that at this point it's not the table or code, per se, since I can generate the plot. Hopefully someone will chime in with more experience who may have seen this error? One thing to try in the meantime... Gather up some gnuplot test data file and try to run it from the command line perhaps? It would at least be one way to see if it's working outside of org-mode?

I ought to have noted that the example works fine when invoked directly from the command line, with the only change being that I move the data into a file (mainly because I don't know the correct gnuplot syntax for putting table data into a variable!). I haven't updated gnuplot since installing it, so I believe the org-mode <-> gnuplot unfriendliness lies in some effect that a recent pull of 7.01trans has had. (I did updated emacs-w3m from cvs the other day, so I suppose thats another possible source of error, but it seems unlikely). I agree that it appears that the table data being handed to gnuplot from org-mode is somehow being formatted in a way that gnuplot does not understand.

I'm using 4.4 as well. Up until today, the gnuplot code blocks using data from org-mode tables worked fine. As of today, the data from the org-mode tables appears to come through to gnuplot in a format that gnuplot cannot understand. I guessing thats why gnuplot is complaining that "data", the variable containing the data from the org-mode table, is a "bad file". Running the aforementioned example from the worg, the *gnuplot* output is gnuplot> data = "((0.1 0.425 0.375) (0.2 0.3125 0.3375) (0.3 0.24999993 0.28333338) (0.4 0.275 0.28125) (0.5 0.26 0.27) (0.6 0.25833338 0.24999993) (0.7 0.24642845 0.23928553) (0.8 0.23125 0.2375) (0.9 0.23333323 0.2333332) (1 0.2225 0.22))" gnuplot> set term png Terminal type set to 'pngcairo' Options are ' size 640, 480 ' gnuplot> set output "basic-plot.png" gnuplot> set title "Putting it All Together" gnuplot> gnuplot> set xlabel "X" gnuplot> set xrange [0:1] gnuplot> set xtics 0,0.1,1 gnuplot> gnuplot> gnuplot> set ylabel "Y" gnuplot> set yrange [0.2:0.5] gnuplot> set ytics 0.2,0.05,0.5 gnuplot> gnuplot> gnuplot> plot data u 1:2 w p lw 2 title 'x vs. y1', \ > data u 1:3 w lp lw 1 title 'x vx. y2' warning: Skipping unreadable file "((0.1 0.425 0.375) (0.2 0.3125 0.3375) (0.3 0.24999993 0.28333338) (0.4 0.275 0.28125) (0.5 0.26 0.27) (0.6 0.25833338 0.24999993) (0.7 0.24642845 0.23928553) (0.8 0.23125 0.2375) (0.9 0.23333323 0.2333332) (1 0.2225 0.22))" warning: Skipping unreadable file "((0.1 0.425 0.375) (0.2 0.3125 0.3375) (0.3 0.24999993 0.28333338) (0.4 0.275 0.28125) (0.5 0.26 0.27) (0.6 0.25833338 0.24999993) (0.7 0.24642845 0.23928553) (0.8 0.23125 0.2375) (0.9 0.23333323 0.2333332) (1 0.2225 0.22))" No data in plot I've not regenerated the plots for a few days - maybe a week - so I cannot be confident that only something today broke this. I'm fairly confident that only org-mode (and as aforementioned emacs-w3m) have changed in my emacs setup.

I tried a bisect and can verify that commit f16c46c856afbd41b115a6a50306c0c002cdb333 is good (release_7.01h-750-gf16c46c) commit b664510ec4811491e4611791c24591153abdf5f3 is bad (release_7.01h-800-gb664510) but the sequence is not bisectable: when it tries the middle commit 2699f4e9bc7695432cf6aaf1dd48e182b10c2847 (release_7.01h-775-g2699f4e) it gets "Symbol's value as variable is void: result-type" and it's not clear to me how to proceed with the bisection at that point. I tried skipping a bit, but the results were mixed at best. So it looks to me as if something in those 50 commits broke it.

It seems there are *two* ways to pass variables into gnuplot. One uses user variables [1], and the other directly replaces variables in the code block [2]. You've been using the former, and I've been using the latter. The bug only existed in the former, but I believe I've now fixed that issue, and in fact I think I'll start using user variables as in your example below. Please let me know if the problem persists after a fresh pull of the repository.
