stacked graphs, with 0 values

[Skinkie]

Currently we have some graphs which have 0 values. Especially when zoomed out it is easy to observed that these attributes are stacked as if per time interval they are at least one. My guess is that this kind of bug must be known somewhere by now.



The red surface is wrong. In general it is added on every timepoint, while it is always 0. And in some valleys it is just plain wrong and looks (integrated) as if there is more output than every recorded.

It depends how did you configure you graph item. I guess that you are using default avg function. Try to change it to min.

What values will be displayed when more than one value exists for an item:
all - all (minimum, average and maximum)
min - minimum only
avg - average only
max - maximum only

I have just done so... and while looking promising at first, it is still wrong.

Pls post just one hour graph.

I see it. IMHO it's standard Zabbix graph visualization (it's a feature :-D)
