I have enabled the add-in ("Analysis ToolPak" and ("Analysis ToolPak
VBA") in Excel (this package seems to come with Excel by default - I
didn't have to install anything special, just had to check the tick-mark
in Tools = Add-Ins). This made another Tools-menu entry appear: "Data
Analysis"

This all works fine, but now I wanted to automatize a few things to save
me some substantial typing and clicking when (re-)generating charts.

So I recorded a macro that uses a function from that add-in (Tools =
Data Analysis = Histogram). In the recorded macro of this action shows
up as:
----------------------
....
Application.Run "ATPVBAEN.XLA!Histogram", , , , False, False,
False, _
False

....
----------------------

When I want to execute/replay the macro I always get an error popup
telling me:

"Histogram - inout range must be a contiguous reference".

I thought, that maybe the series of empty ', , , ,' indicates some
missing or non-recorded range inputs (namely the input range, the
"buckets" and the output range that I entered during recording) and
tried to fill the void so that the line read
----------------------
....
Application.Run "ATPVBAEN.XLA!Histogram", "$B$10:$K$508",
"$O$2:$O$255", "$P$1:$Q$256", False, False, False, _
False

....
----------------------
.... but that did not work either and so I am stuck.

Any idea, what to do here or what I am missing? How/where can I find
some documentation re. what parameters that Histogram-operation expects?

Any help would be greatly appreciated!
