Charts feature request - Stick ruler on chart area and copy numerical ruler values to clipboard

In the chart area in Cognite Charts, it would be beneficial to lock the ruler in place on the screen, cause I often have to switch windows and write down say inside excel. and I want to copy values from charts, now i do that through taking a printscreen but it is quite cumbersome to open mspaint to copy it in, and find the window and the values inside the printscreend browser-window. could be expanded to be able to add in multiple rulers. such that the rules with numerical values stay on the screen even if I change windows and move the mouse away from the charting area. 

It would even be nice, if with a button the values along the ruler could be store to clipboard as text string such that they can be copyed straight into a say excel spreadsheet or into any text-document.
