It would be nice to be able to group charts in the dude so that they could be easily found, by having more than one tree level in the tree view in the top left pane of dude. Or, maybe if a chart could be associated with a device, make the chart accessible by right clicking the device and selecting a menu option.
It would be good to have a legend when graphing more than one OID.
Also I would be better to be able to set graphs when you hover over a device..
There is already a legend. Right click on the chart to show/position it.
