Line chart widgets will display dynamic data from entities. However we often want to display this information in relation to a fixed "target" value, or perhaps a "threshold".
Examples:
* DORA metrics - where we set a goal of reducing our recovery time to below X hours
* Tech Debt / Security - where we specify that a service should be reviewed if the backlog of issues raises above a threshold
* Scorecards - where we want a visualisation of an entity in relation to scorecard thresholds
It would be very useful if, in the line chart widget config, we could define one (or more) such static values, and have these overlaid on the chart. Further, these "static" data series would be visually distinct from the data pulled from entities. See attached image as an example.
Workaround: I realise it's possible to add a property to the relevant entities, which holds the fixed value of your target/threshold. However this has limitations:
* The same target/threshold value needs to be populated on multiple entities. Some blueprints have a lot (maybe hundreds) of entities (e.g. services), and maintaining these values would require building out process/automations
* This new data series would be assigned a label and colour just like any other data series - i.e. there is no visual distinction between "data" and "target/threshold", other than the fact that one of them happens to be a straight line!
