plotting when x-axis has non-numeric data

plotting when x-axis has non-numeric data

[henry atting]

I have a table which I am plotting longly, it looks like this:

#+PLOT: title:"expenses" ind:1  type:2d with:lines 
#+PLOT:  set:"yrange [0:]" labels:("month" "expenses" "average") 
| month       |   two |three|
|------------+--------+-----|
| November    | 500   | 500 |
| December    | 500   | 500 |
| January     | 600   | 500 |
| February    | 400   | 500 |

Thus far it was no problem that the x-axis contains non-numeric data.
Now gnuplot stops with this error message:

gnuplot> plot '/tmp/org-plot18686CtJ' using 1:3:xticlabel(1) with lines title 'H-index'
           warning: Skipping data file with no valid points
          x range is invalid

When I try to plot the table 'Citas' from this tutorial [1] I get the
same error message.

Okay, I see; for some reason the following statement is not more valid:

,----[ From: http://orgmode.org/worg/org-tutorials/org-plot.php ]
| Org-plot can also produce histograms from 2d data, plot the following
| table. Notice that the column specified as ind contains textual
| non-numeric data, when this is the case org-plot will use the data as
| labels for the x-axis using the gnuplot xticlabels() function.
`----

As far as I see, you have to do it with org-babel now, which works just
as well for me.

Hi Henry,

Thanks for bringing up this bug.

While for any serious plotting I would certainly recommend using
Org-babel over org-plot, org-plot should still function correctly.  I've
just pushed up a fix to the bug you described, so your previous table
should work once again.

Thanks -- Eric

Yes, it works fine again. 
As the Zen Master T.Deshimaru said (Zenglish he used to call his broken
English): `Bad Become Good'
But for the bug maybe I would not have dealt too much with the
org-babel (which is really great)

Thanks,
henry
