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.
