Thought so. Thanks for confirmation.

My gnuplot (Version 4.4 patchlevel 2) returns:
,----
| gnuplot> help boxplot
| Sorry, no help for 'boxplot'
| gnuplot>
`----
gnuplot-doc is installed. Do I miss something else? «help
candlestick» works. Is «boxplot» a part of an additional extension
package?

Your example works like charm at my side.
And now I also understand the problem I had: I thought that gnuplot
is able to derive min/max whisker min/max from the data columns by
itself.
Well - this is bad news to me since I do not see any reasonable way
to use gnuplot for that purpose. I might need to learn R or
Python/matplotlib :-(
Thanks for your help anyway!
