Can we make this feature optional?
Assume enabled by default - but it could be disabled by some option.

Can we make this feature optional?

Why would someone want to disable this? It only fills missing data from the past in case it has been purged from the recorder.

This is clear, I am asking from a point of view of a person who may not be able to see a visual difference between a “history” curve and less vivid “statistics” curve. That is why we probably should add a boolean option for this “augmentation”.

[MindFreeze]

I still don't understand but the thing is that if we add any options to this card, people will start requesting them for the history panel too as the card is a mini version of that

Agree, but history-graph card also has other options like for min/max bounds, show/hide names which are (obviously) not provided for History page/more-info.
Providing an option for that “augmentation” will add a possibility to see clearly where a real history ends. As I already said - currently for some people it is not clear where it ends because a color difference is slightly visible.

I still don't get the reason of having a boolean option then? What would it solve?

[ildar170975]

My proposal was:

1. Add a new boolean option like “show_ststistics”. Default = true.
2. If false - then the card will not be “augmented” by LTS.

Yes, I get your suggestion, I just don't understand why you would want it, what problem does it solve?

[ildar170975]

Sometimes to perform an analysis we need to look at the “pure history data”. A visual difference between statistics and history curves is slightly visible which causes a problem for people with damaged eyes (or just old people).

[MindFreeze]

Needing to differentiate "pure history data" seems like an edge case for a card. It makes more sense to do this in the history panel. And we could improve the styling to make it more visible.
