After upgrade to Version 0.8.7g some graphs not updated

[freakcity81]

Hello,
after I´m upgrading to Version 0.8.7g some of my graphs at some devices are no more updated. I add those device once again to cacti but nothing happens. In the logfiles cacti.log and poller.log there ar no erros.
Anybody knows why some graphes are not created, like in attachment (graph.jpg)?
Thanks for your answers.

[edit]
How i can change the existing Poller Interval, because all data sources which have polling interval 1 Minute the are no graphs. Those who have 5 Minutes Interval the are graphs. On the Screenshot (data_source.jpg) below you see the differences.
On system Console System settings, the Poller and crontab interval is already 5 Minutes.
