Many times we are trying to correlate changes between various graphs (e.g. SQL Latency vs some go runtime stat). This is pretty hard when the graphs are in separate dashboards. It is especially hard to produce a screenshot that shows the relevant graphs.

Ideally, there would be a way to show any graphs below each other, with the same time axis. One idea would be to allow multiple dashboard to be visible. Another (better) idea would be to allow "pinning" or "starring" graphs and having a dashboard with the starred graphs.
