Full Utilizations are not shown for Tunnel Graphs of Router NE40E in Newer Version (1.2.20)

[kalanabg]

Current Cacti Version : 1.2.20

Full Utilizations(Bits/second) of tunnel Graphs of the Huawei NE40E Device, which are visible in the old Cacti version (0.8.8 ) are not totally visible(only Low Utilizations are visible ) in the new version (1.2.20). In New version the tunnel Graphs are like cropped only to show the lower bits per second as shown in attached image

Is there any method to adjust and auto scale the Utilizations (bits/second) in Tunnel Graphs. (This issue only present in Tunnel Graphs)
Please mention any probable cause for this issue and any updates to rectify it.
