Problem with custom stacked graph

[ianh]

Hi all

Seem to be having a problem with the graph module. Im using 1.1beta7

Have tried to created a stacked graph and have had some success.
When the graph is displayed there seems to be quite a few spikes.
This is apparent when the period is between 1h and 4h.. But when it is greater than 8 hours, it seems to be fine.

Screen shots are attached...

The values that i am retrieving in are correct, as these "spikes" seem to occur at random locations whilst the graph is refreshing.

Any ideas what could be causing this. Thanks in advance.

Stacked graphs? Threse are not stacked graphs! ZABBIX does not support it yet.
