[pve-devel] [PATCH widget-toolkit v3 1/2] rrdchart: allow to override the series object

[Aaron Lauterer <a.lauterer@proxmox.com>]

this way we can keep the current behavior, but also make it possible to
finely control a series if needed. For example, if we want a stacked
graph, or just a line without fill.

Additionally we need to adjust the tooltip renderer to also gather the
titles from these directly configured series.
