Display min and max values on top of the trace as text, at the correct x positions

[r-jean-pierre]

Describe the solution you'd like
If not already asked, can we have the min and max value text on top of the curve?" it seems that plotly do not have this option right out the box, but they suggest to the users to construct this feature with the add_annotation feature (https://plotly.com/python/text-and-annotations/)
and then, a possible result could be equivalent to:

How would it be defined in yaml?

type: custom:plotly-graph
entities:
  - entity: sensor.monthly_internet_energy
    show_extremas: true

wdyt about show_extrema or show_extremes or show_min_max_value ?

[r-jean-pierre]

All of them are okay. As a lazy boy I did the concatenation of

show:
  extremas: true

from the apex-charts card into show_extremas

But now I just realized that's wrong extremas with the S, it's a latin word, so: 1 extremum, several extrema, so apex-charts writes it wrong :)

[dbuezas]

exactly!
