History-graph: do not make a graph for "unavailable" sensor transparent

Describe the issue you are experiencing

Since 2022.12.4 a graph for "unavailable" entity is shown of transparent color.

This is confusing:

1. No graph for some entity may be considered as bug.
2. Transparent color = gap, but currently a gap is displayed in cases when an entity does not exist.

And when within the selected period the entity is unavailable - then no graph is displayed at all:

which is super-confusing.

Describe the behavior you expected

Graph for "unavailable" sensor must not be transparent.
Better to use some theme variable like --history-state-color-unavalailable.

What can be considered as a bug is that we don't show a label.

Like I said earlier: unavailable being transparant communicates a correct message, saying it's not a value like on, off, clear, etc. It's not that common an entity doesn't exist, only a first time. Note that your example is of 4 minutes, that's not a regular use case in my opinion.

And when within the selected period the entity is unavailable - then no graph is displayed at all: which is super-confusing.

That isn't consistent indeed. We should keep the same design pattern.

communicates a correct message,

But many people in Community disagree.

Also, since currently you implemented a "color for icon = color for history" way for domains -> are you going to make a transparent icon for unavailable entities too? ))
Not to mention a fact that your change to transparent just breaks people's expectations like "I see grey - means unavailable".

It's not that common an entity doesn't exist, only a first time.

Unclear, what do you mean?
The "entity does not exist" is a very common case.
Especially when HA is on development stage (which may be a permanent state for some people).

Note that your example is of 4 minutes, that's not a regular use case in my opinion.

Not sure what "4 minutes" you are talking about. But if you mean the 1st screenshot - this is a test case which is used for testing (a term we are missing a lot). And this case demonstrates an issue.

I have to disagree to the following statement:

It's not that common an entity doesn't exist, only a first time.

unfortunately, "Unknown" happene every time, when you have a cloud-based integration and the connection could not be established - or, if the integration could not be loaded, or similar...

Let me show you an example:

While I can fully agree with missing information in the Graph -> no data to record at all, the STATE should at least indicate SOME information.

Unfortunately, with only a lable, it does not work in all cases, because probably, on several occurances there's not the required space to write the label.

A label on a transparent bar may be not even noticeable.
Not to mention already described reasons like

• absence of a graph treated by many people as a bug;
• will not be possible to distinguish unavailable case & "does not exist" case;
• since icon color = history color, it is meaningless to use transparent icon color for unavailable.

May be closed - as long as --history-unavailable-color var is supported.
