Hi all,
I try to plot a table looking like this
| Date | Kg |
|-----------------+--------|
| 2010-02-21 | 95.0 |
| 2010-02-22 | 93.0 |
| 2010-02-23 | 92.0 |
| 2010-02-24 | 91.5 |
| 2010-02-25 | 91.0 |
| 2010-02-29 | 92.0 |
| | |
with the dates on the xaxis using
#+PLOT: title:"Weight" ind:1 deps:(2) type:2d with:linespo set:"xdata time"
timefmt:%Y-%m-%d set:"yrange [90:]"
but no plot is generated. If I remove <set:"xdata time">, the plot is
generated but without interpreting the dates as dates.
Can anyone see what I do wrong?
Thanks in advance,
Johan

However, looking at the gnuplot comint buffer created, there is an error message that indicates that plotting xdata in time format requires a using statement to specify directly the columns to plot. I have tried, therefore, the following specification on the plot line: --8<---------------cut here---------------start------------->8--- #+PLOT: title:"Weight" ind:1 deps:(2) type:2d with:linespoints set:"xdata time" set:"timefmt '%Y-%m-%d'" set:"yrange [90:]" ind:1 deps:(2) | Date | Kg | |------------+------| | 2010-02-21 | 95.0 | | 2010-02-22 | 93.0 | | 2010-02-23 | 92.0 | | 2010-02-24 | 91.5 | | 2010-02-25 | 91.0 | | 2010-02-29 | 92.0 | --8<---------------cut here---------------end--------------->8--- I had to put quotes around the time format and also (just in case) spelled out linespoints fully. However, this still doesn't work because org-plot/gnuplot generates the following plot command: ,---- | plot '/tmp/org-plot1831zcQ' using 2:xticlabel(1) with linespoints title 'Kg' `---- Note the strange using parameters! I am not sure where this is coming from unfortunately. Note that if I type this in directly in gnuplot, with "using 1:2", everything works just fine. eric ^ permalink raw reply [flat|nested] 13+ messages in thread

Hi Johan, I've never used matplotlib, but here's a start. Firstly, one thing I notice is that org-babel-python currently doesn't like the column names on the table (I'll add it to our TODO list). So if we make a table like this, without the header: #+results: my-table-nohdr | 2010-02-21 | 95.0 | | 2010-02-22 | 93.0 | | 2010-02-23 | 92.0 | | 2010-02-24 | 91.5 | | 2010-02-25 | 91.0 | | 2010-02-26 | 92.0 | Then pass the data into python and have a look at what we've got: #+begin_src python :var data=my-table-nohdr :results output print str(data) #+end_src #+results: : [['2010-02-21', 95.0], ['2010-02-22', 93.0], ['2010-02-23', 92.0], ['2010-02-24', 91.5], ['2010-02-25', 91.0], ['2010-02-26', 92.0]] So if you know how to use matplotlib to create your plot using that list of lists, then you should be set. To get output to file you will need to use something like :file pyplot.png, *and* arrange that your code writes the graphical output to pyplot.png. A link to pyplot.png will be inserted in the org buffer. Given my ignorance of gnuplot and matplotlib, I would use R. Unlike python, but like gnuplot, the graphical output is automatically sent to the specified file, without having to explicitly tell R to so so: #+begin_src R :var d=my-table :file R-plot.png plot(as.Date(d$Date), d$Kg, ylab="Kg", type="b") #+end_src #+results: [[file:R-plot.png]] Dan > > Babel seems super cool! > > /Johan > > On Tue, Feb 23, 2010 at 3:47 PM, Eric Schulte <schulte.eric@gmail.com> wrote: > > Hi Johan, > > You could try plotting your table using standard org-mode date formats > which org-plot will understand without any need to specify a timefmt > string. > > #+PLOT: title:"Weight" ind:1 deps:(2) type:2d with:linespo set:"xdata time" > set:"yrange [90:]" > | Date | Kg | > |------------------+------| > | <2010-02-21 Sun> | 95.0 | > | <2010-02-22 Mon> | 93.0 | > | <2010-02-23 Tue> | 92.0 | > | <2010-02-24 Wed> | 91.5 | > | <2010-02-25 Thu> | 91.0 | > | <2010-02-26 Fri> | 92.0 | > > Alternatively if you want more control over your plots and more direct > access to gnuplot you can use org-babel to pass your table directly to > gnuplot as follows. > > #+results: my-table > | Date | Kg | > |------------+------| > | 2010-02-21 | 95.0 | > | 2010-02-22 | 93.0 | > | 2010-02-23 | 92.0 | > | 2010-02-24 | 91.5 | > | 2010-02-25 | 91.0 | > | 2010-02-26 | 92.0 | > > #+begin_src gnuplot :var data=my-table > set xdata time > set timefmt '%Y-%m-%d' > set yrange [90:] > plot data using 1:2 with linespoints title 'Kg' > #+end_src > > Best -- Eric > > Johan Ekh <ekh.johan@gmail.com> writes: > > > Hi all, > > I try to plot a table looking like this > > > > | Date | Kg | > > |-----------------+--------| > > | 2010-02-21 | 95.0 | > > | 2010-02-22 | 93.0 | > > | 2010-02-23 | 92.0 | > > | 2010-02-24 | 91.5 | > > | 2010-02-25 | 91.0 | > > | 2010-02-29 | 92.0 | > > | | | > > > > with the dates on the xaxis using > > > > #+PLOT: title:"Weight" ind:1 deps:(2) type:2d with:linespo set:"xdata > time" timefmt:%Y-%m-%d > > set:"yrange [90:]" > > > > but no plot is generated.

Eric, thanks for this suggestion as well as the one using org-babel (which I would have typically used myself these days). However, the point still stands: why doesn't what Johan tried initially work? I have narrowed down what causes the problem although I don't understand why (I haven't had any time to look at the elisp code). Basically, the problem with Johan's initial table was the extra empty row at the end: --8<---------------cut here---------------start------------->8--- #+PLOT: title:"Weight" ind:1 deps:(2) type:2d with:linespoints set:"xdata time" set:"timefmt '%Y-%m-%d'" set:"yrange [90:]" | Date | Kg | |------------+------| | 2010-02-21 | 95.0 | | 2010-02-22 | 93.0 | | 2010-02-23 | 92.0 | | 2010-02-24 | 91.5 | | 2010-02-25 | 91.0 | | 2010-02-28 | 92.0 | | | | --8<---------------cut here---------------end--------------->8--- With the empty row there, the "using 1:2" option to the gnuplot plot command is not generated correctly, instead generating "using 1:xticlable(1)" which gnuplot doesn't like!

It looks like the empty last row is tricking org-plot.el into thinking that the entire Date column contains text labels, so it tries to use the values of that column to label the data with xticlabels [1].

Well, good intentions is one thing, wrong behaviour is another? If the user has specified "ind:1 deps:(2)", even if org-plot identifies column 1 as having labels for the tic marks, the generated parameter to the plot command should be, at best: ... using 1:2:xticlabels(1) ... which is actually nonsensical as well but not as bad as what is currently generated: ... using 1:xticlabels(1) which completely ignores the "deps:(2)" option! In any case, I'm not suggesting in any way that this is a critical bug! Simply removing the empty line allows org-plot to work perfectly. ^ permalink raw reply [flat|nested] 13+ messages in thread

All of the plots form the org-plot page on worg still work with this patch (which amounts to org-plot's test suite), so I relatively confident that it shouldn't break any existing functionality. One problem with org-plot's attempt to guess the best action in each situation is that the code will get increasingly ugly as these corner cases continue to arise, and as that happens it becomes increasingly difficult to know a-priori if a patch will cause unforeseen problems.

Yes, I can imagine. I guess, for Johan's benefit, that it's best to move on to org-babel for the more complex problems leaving the direct gnuplot support for "simple" cases!

Today I faced the same problem and I fixed it by replacing ``timefmt:%Y-%m-%d`` with ``set:"timefmt '%Y-%m-%d'".
