Hi,
I am using Graph Builder to display:
- the number of defects within a batch as parts are processed through a certain manufacturing tool TOP PLOT
- the E10 Equipment State changes the tool went through during the same time period CENTER PLOT
- a process monitor taken from test substrates also processed during the same period. BOTTOM PLOT

The "updated_date" is the only common factor between all data sets, which have been collected from 3 different databases
I would like to have the possibility to have an X Reference line displayed while I click and hold the mouse on any of the plots. On mouse release it should disappear.
The Reference line should be displayed across all plots simultaneously.
An example of what I need is seen below:

Looking forward to seeing what creative solutions may be provided
