[Feat]: Ability to show multiple metrics on one chart

[skwerlman]

Problem

I want to have an overview of the total power usage of one of my nodes. Power usage is collected as three metrics:

• cpu.powercap_intel_rapl_zone, grouped by zone
• cpu.powercap_intel_rapl_subzones, grouped by core
• nvidia_smi.gpu_power_draw, grouped by product

Right now, I have a dashboard with each chart, but it is difficult to use since getting the total estimated power involves doing math in my head (i am not good at it haha). Additionally, it is difficult to compare the power usage of package vs core vs gpu at a glance since their charts have different y-axis scales.

Description

I would like to be able to have a single stacked chart on my dashboard which shows the wattage reported by both RAPL and nvidia_smi, grouped in the same way as above.

In addition to the described problem, this would also help for providing a combined view of all temperature data from the various sensors in my system (mobo, cpu, gpu, drives, etc) to get a better picture of the thermal state of the system

Importance

really want

Value proposition

1. This would improve viewing of closely related metrics from disparate sources by allowing them to share a single scale for the y axis
2. This would enable at-a-glance viewing of aggregate usage for whatever resource the user wants to monitor (some specific subset of drives, or power, or any other scenario where a single resource is shared by otherwise unrelated systems)

Proposed implementation
