Non-numeric, non-binary sensor support

[Line-Noise]

G'day!

I'd like to use mini-graph-card to display tide times (next high tide time, next low tide time) and plot graphs of the historic tide height for each. The tide heights work great but because the sensor value is a date I just get NaN.

Is there a way to show the literal value of a sensor if it's not a number?

Wait, if values are dates...... what are those numbers on the left side? I guess your Y is date/time, and X is the height, right?

X is always a time. Y is allays a sensor’s (attribute’s) value. What is posted in the issue is barely clear since the author omitted both the card’s code and a description of his values. No wonder there is no any movement with this issue.

Yeah, fair enough, I should have included the card's code. My bad.

Sadly, I don't have a copy of the card code anymore because it wasn't working for me. So I'll have a go at recreating it from memory.

I have a tide sensor that provides:

sensor.high_tide_height
sensor.high_tide_time
sensor.low_tide_height
sensor.low_tide_time

So I did something like

entities:
  - entity: sensor.low_tide_height
    show_state: false
  - entity: sensor.low_tide_time
    show_state: true
    show_graph: false

The graph of the tide height in metres worked fine. But the low_tide_time is a string value which, of course, is not a number, hence the NaN. My request was for support to display arbitrary strings as state values. They couldn't be graphed, of course, hence the show_graph: false, but I don't see any reason why the state needs to be a number.

Please post also an example of values kept in that non-numerical sensor. A screenshot from Dev tools -> set state.
