Open one of the graph URLs in a separate window and add &debug=1 to the end of the URL.
Picked one at random - a whole lot of SQL … and the only “red” errors: 
SELECT COUNT(*) FROM `ports` WHERE `pagpGroupIfIndex` = '2' and `device_id` = '274'
Error in query: (Unknown column 'pagpGroupIfIndex' in 'where clause') 1054
Not sure if that helps. 
This has been dropped from the table ports  - update 297.sql 
update/297.sql:ALTER TABLE  `ports` DROP  `pagpOperationMode` ,DROP  `pagpPortState` ,DROP  `pagpPartnerDeviceId` ,DROP  `pagpPartnerLearnMethod` ,DROP  `pagpPartnerIfIndex` ,DROP  `pagpPartnerGroupIfIndex` ,DROP  `pagpPartnerDeviceName` ,DROP  `pagpEthcOperationMode` ,DROP  `pagpDeviceId` ,DROP  `pagpGroupIfIndex` ;
Not sure where else to check?  
Also have this !
Also, please don't hijack existing list threads
Sorry ;(
