#48 After upgrading VPS from 1 core to 4 cores CPU graph does not draw to top of chart

[Eugene van der Merwe]

After upgrading a VPS from one core to four cores the CPU graph only seems draw to the first core/line. I don't mind loosing old CPU statistics and just really want to reset RRDTool for this metric if possible.

I have attached an image to show the issue. Please would you guide me on how to reset RRDTool for this graph? I tried uninstalling and re-installing Webminstats but that didn't work. The uninstall worked but a clue was when I re-installed it said most of the modules are already installed, so I suspect it didn't remove any data.
