Performance Graphs for some services are broken

[uidaho]

We have NSClient++ 0.4.1.102 deployed.

Switching to use High Charts did fix the problem. Thank you! I am having my team check graphs to make sure they don't have any problems with this style of graphs, and hopefully I can put this issue to rest.

Thank you!
