One feature that I really miss are histograms (this is dealt in issue 49971, see

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

Overlapping histograms should allow *colour overlaying* to preserve visibility.
This is best viewed in the following example: (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: and various
other examples on .

Comment 3 IngridvdM 2007-11-09 11:59:47 UTC
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.
