Histogram graphic don´t show lines when event numbers are high

[Sandro Merg Vaz]

Hello all!
 
Today i was generating some alert histogram reports, and some weird
thing has happened...
 
When the number of recovered, down and unreachable events are higher
than 200 (in a day or month), for example, the lines in the histogram
alerts don´t show up. If these values are lower than these limit,
everything seems fine... 
I believe that´s is a Y-scale problem, because when the lines doesn´t
appear, the Y-scale numbers doesn´t appear too...
 
I also looked int the code of histogram.c to see if there is a max
number of events that this program is able to process, but i´ve found
nothing.
 
Is it a known bug? I´ve also looked at the mailing list, but didn´t find
nothing closer to my problem...
 
Any help or idea?,
 
TIA,
