Allow precise horizontal alignment of graphs

[ppetr]

Why is this needed: When there are multiple graphs with different labels, each of their x axes is aligned slightly differently:

This makes it more difficult to analyze times and connections of events occurring in multiple graphs.

What would you like to be added:

1. Add an option that would cause all graphs to be perfectly horizontally aligned. That is, that two points on the screen corresponding to the same timestamp would have the very same horizontal position on the screen (the same screen x coordinate).
2. (Can be implemented independently of 1.) When hovering over a graph, show the vertical hover marker (cross) not just in the single graph, but in all graphs at the same timestamp.
   

Who is this feature for?

For data analysts that investigate causality relationships between events.

Add an option that would cause all graphs to be perfectly horizontally aligned

this is a hard problem when you can have multiple y axes, different formatting/units, different y ranges, and completely arbitrary panel widths + arrangements.

When hovering over a graph, show the vertical hover marker (cross) not just in the single graph, but in all graphs at the same timestamp.

this exists in dashboard settings called Shared crosshair or Shared tooltip.

Perfect, I didn't know, thank you!

Just specify a fixed width for the y Axis for both charts and the x-Axis will align. You will however have to place all y-Axes on the left.
