Description discoleo 2007-05-30 20:14:01 UTC 
One feature that I really miss are histograms (this is dealt in issue 49971, see
http://www.openoffice.org/issues/show_bug.cgi?id=49971).

An extension to the previous issue are overlapping histograms. These are
especially helpful when studying multiple groups of data. One application field
is in data mining. [Please note that data mining is extensively used by big
corporations.]

Overlapping histograms should allow *colour overlaying* to preserve visibility.
This is best viewed in the following example:
http://rapid-i.com/images/stories/rapidi/yale/screenshots/screenshot14.gif (see
also the other examples on the site for various data-mining techniques).

It would be surely useful to have the ability:
  - to plot multiple histograms (or other charts simultaneously) AND
  - have the ability to set various colour overlaying modes
     - add, XOR, ...
     - transparency, ...
     - IF ( overlap ) THEN slight shifting

For other types of simultaneous plots, see also:
http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=136 and various
other examples on http://addictedtor.free.fr/graphiques/ .

@Iha: one good idea for you.

I believe overlapping histograms will become available automatically when these
other features are implemented before:
1) Histogram charts ( issue 49971 )
2) Independent x axis ( issue 78093 or maybe issue 7637) 
Maybe point 2 is even not necessary.
You can make bars transparent already now.
I will not implement additional complex mechanisms for this.
So state is somewhere between duplicate and won't fix.
