Local Mango system with a persistent module collected all data from other remote Mango sites. In Graphic views, I created all data points display renderer charts. However, after a while I found that all the "Chart renderer properties" are set to "None". My Graph view cannot show the renderer charts any more. When I changed it back to image for 1 hour period. The alarm log showed that it was done by "unknown" user (I logged in as "admin"). Please help to fix. Thanks !
