When I changed the minimum for the colour scale to -0.5, the colour 
problem vanished and all my maximum values had the right colour.

Subject: 2d histogram: right number but wrong colour in col mode

Hi,

I am using v4.00/01
I am filling a 2d histogram (wihtin a C porgram) , with:
correl->Fill(i,j,p);
where i and j are integers and p is a float.
Now my problem is that when I draw the histogram in col mode sometimes the 
color isn't right when my entry is 1, 1 being my maximum value. With a 
palette from blue to red, sometimes it would be blue and sometimes red 
eventhough the entry is one :(
Any idea of what I might be doing wrong ?
I have attached two pictures where the diagonal illustrates the problem.

Cheers
