Trying to get chart from table working

Trying to get chart from table working

[Peter Davis]

I'm trying out the org-plot example, but when I enter C-M-g on a table, 
I get:


Cannot open load file: No such file or directory, gnuplot


I verified that gnuplot is installed, and that /usr/local/bin is in both 
the PATH and the exec-path for emacs. Is there something else I need to do?


Ultimately I'm trying to figure out how to plot a time series graph, and 
then to represent different time intervals with colored bands in the 
background.


Thanks,

-pd

It may refer to gnuplot.el (found in gnuplot-mode debian package for me)
as I think org uses this to execute gnuplot commands?

Thank you, Eric. I did install gnuplot-mode via the list-packages
interface, but I can't find a gnuplot.el file on my system.

Aha! Just installing gnuplot did something. Now I get

Re: Trying to get chart from table working

[Peter Davis]

I'm sorry to belabor this, but I could use some help. I'd be willing to
pay a modest consulting fee, but I'm trying to solve a problem in a
timely way, as it would help me with healthcare decisions.

Basically, I want to plot a time series graph showing my PSA (prostate
specific antigen) over time. The PSA is measured at irregular intervals,
and has been for over 4 years (and hopefully will continue for many more
years.) That should be a simple enough graph. I've already got a
javascript d3 example that does this, but I'd like to embed it in a
document, and to be able to generate PDF.

Further, I want to be able to show different time intervals with tinted
bands spanning the full range of the graph, and having specific start
and end dates. These would represent various medical treatments I've
undergone. I have a rough example I've mocked up in Photoshop, but, of
course, I want to be able to add new data and re-generate the chart as
needed. I don't know if I can attach a PNG to an email on this list.

Unfortunately, I don't have enough emacs lisp knowledge, or org-mode
knowledge, or gnuplot knowledge to know how to make this all work. I
have not even be able to get the org-plot example to work. (I have been
using org for various types of documents for a number of years, and can
generally pick things up quickly, but I'm overwhelmed by this.)

I was thinking of having a table like:

----
...
| *Date* | *PSA* | *Treatment* |
| 2017-08-11 | 185 | |
| 2017-08-21 | | #ffdd99 |
| 2017-09-19 | 854 | #ffdd99 |
...
----

So some rows would contain a PSA measurement, some a background tint,
and some both. I've never seen a visualization like this, but I think it
would be very helpful to have a single timeline that shows periods of
various treatments and the PSA value. There are probably better ways to
specify the starting and ending dates of treatments, but this seemed
amenable to simple iterative processing.

I've considered possible tools for this, including d3, PostScript, etc.,
but I think Org would be best for maintainability, allowing me to add
notes, etc.

I know this is a tall order, but it's beyond my capabilities right now.
Any recommendations or suggestions greatly appreciated.

Thanks,
-pd

This part is relatively straightforward.  Using your data example, you
can do the following:

The colouring bit is harder and I don't know whether it's possible or
not.  I suggest you look at examples on the web, e.g.

http://gnuplot.sourceforge.net/demo/

to see if anything fits what you are trying to do.

Thank you for the example, Eric. Running this gives me a page with the
table and the code on it, but no plot. Here's what *Messages* says:

Do you get the following lines?
(you can erase them, they will be recreated).

   #+results:
   [[file:timeseries.pdf]]

If you click on the link, it should open okular or acrobat reader or 
whatever displaying the plot.

Otherwise you can try a different format, PNG for instance:

   #+begin_src gnuplot :var data=measurements :file timeseries.png 
:results inline

I do have those lines in my .org file, but no PDF was produced. I tried
switching to png, but still no file was produced.

Check the *gnuplot* buffer to see if there were any gnuplot errors.

I do something similar for managing diabetes.

I use org-mode to manage some (not all) of the data tables and org-babel
to control a graphics and statistics analysis in R.  R can also handle
input in other formats, such as CSV, that I get from some sources. The
results are also displayed in the org window as output from R.

This is a much heavier weight solution, since it involves learning R.  But
the graphics capabilities are immensely richer than gnuplot and the
mathematical capabilities for statistics and time series analysis are
immensely richer in R.

If learning R benefits your work or career you might explore this.

Thanks, Robert. I've had considered R as a possible tool for this
effort. I actually used it briefly for a data visualization course I
took a few years ago, but there's still a lot more learning I would have
to do to accomplish this. 

On the other hand, it seems every other path I've tried has a large
learning curve too, so I should give R another look.

Thanks,

Okay, maybe not when you export but what if you manually execute the
gnuplot src block?  Do you get the PDF file generated?  If not, you
should have a *gnuplot* buffer which you can then look at for errors.

Trying to run the table manually (C-M-g) just gives me:

Oh, execute C-c C-c in the block gives me

No org-babel-execute function for gnuplot!

So I guess something's not installed (correctly).

I added (gnuplot . t) to my org-babel-load-languages, and now I'm back
to

Wrong type argument: arrayp, nil

Sigh.

FWIW, this is what I get in the *gnuplot* buffer when I C-c C-c on the

Very strange.  Try M-x toggle-debug-on-error RET and then post a
backtrace?
Also maybe post your complete example.
What versions of gnuplot and org do you have installed?

My gnuplot is patchlevel 7; maybe this makes a difference?  The table
does have gaps in it and maybe gnuplot has improved in how it handles
such data.

For the OP, it may be worth ensuring that all entries in the second
column have data in them...

I'm using the same t.org file you sent a couple of days ago.

Gnuplot says it's V5.2, patchlevel 0
Org version is 9.0.9

By the way, I tried filling in a tint value in the first row, and a PSA
value for the middle row, but got the same error.

Thanks!

So it's not gnuplot, I would guess.  Could it be that you have a mixed
org installation?  Grasping at straws here...

Peter,

can you export *anything* to html? Or maybe export anything with
a table that includes a date? The backtrace seems to implicate this
latter scenario.

This seems like a more generic error in the export engine and since
nobody else sees it (afaik), I tend to agree with Eric F. that it
might be your installation that is at fault.

Yes, I can export to both HTML and LaTeX/PDF, including tables with
dates, etc.  However, the document Eric sent, t.org, gives me the same
'wrong type argument' error. I'm assuming this is due to the gnuplot
instruction block in the document.

Thank you,

So if you delete the source block from t.org, you can export the file
with no problems, correct?

Yup. I deleted the source block and the results line, and now export to
HTML and PDF works with no problems.

Ok. The original (t.org) is exactly what you posted a few days ago. This
fails to export HTML. ("Wrong type argument")

The other file (t2.org) has the empty table cells filled in, and has the
SRC and RESULTS blocks removed. This exports to HTML or PDF with no
problem.

By the way, I just re-installed Org from the package manager, so I'm now
at

Org mode version 9.1.1 (9.1.1-17-g24ea1b-elpa @
/Users/peterdavis/.emacs.d/elpa/org-20171002/)

I was hoping this would fix any possible installation inconsistency
problems. Is there a better way to do this?

Thanks,

Both export to HTML with no problems for me.

It's not so much which version has been installed but whether you are
picking up this version as opposed to the one built-in to Emacs.  You
have to make sure this version is picked up when org is loaded.  Do you
have any org related aspects in your initialisation that may be invoked
before Emacs is told about the new version?

I tried running emacs in a shell window with no initialization file, and t.org <http://t.org/> *did* export HTML, and PDF (although I *still* don’t get the graph).

So yes, I guess there’s something in my init file that’s messing this up.

Chances of finding it in my lifetime: near zero.

Meanwhile, I have discovered a Google charting function which gives me an annotated time series graph that comes very close to what I need. Also, I’ve had no problems exporting many other documents to HTML and/or PDF. So I’m afraid solving this has dropped on my priority list.

Thank you all for your help,

Frustrating that you have not managed to get this working in Emacs with
org but I'm glad you found a solution to the real task.

As another data point, I cannot reproduce the error with "t.org".

Thanks. It seems I have two problems:

1) Something in my emacs/org setup is causing this to fail outright,
with a "wrong type parameter" error. If I run in a shell window with no
init files, I don't get that error.

2) Something is preventing gnuplot from working. Even when I can
successfully export to HTML or PDF, I don't get any graph.

Thanks,
-pd
