Graphs in Hyperic monitoring system?

Question

Monitoring

I understand this system, and I still can’t understand, is it really impossible to create a graph in Hyperic , where, in the form of several curves, the dependence on processor load / memory consumption / hard disk space / number of users will be displayed?
I saw the plugin: Wall Mount Visualizer, but it is dead since Nov 29, 2011, and it has little functionality.
