The biggest and most complex release of the year!

Open for beta testing!

Universal functions allow you to communicate across the yaml, combine datapoints from multiple entities into one, add the state of a sensor to the name of the trace, etc.
show_value now can print out of the plotting area
Semi-persistant cache: resetting the plot doesn't delete data anymore
Efficiency: offset entities share the same cache with non-offset ones.
Added almost all plotly plot types, including histograms, 3dscatter, surface, heatmap, piechart, ... Find inspiration here (maps not included)
Added a delta filter (more to come!)
New raw_plotly_config yaml option to disable all in-built defaults (useful for non-standard plots)
Home Assistant themes' color variables available inside Universal Functions ($fn)
Respect fixed range axes when pinch zooming
Improved pinch to zoom algorithm
Universal $fn functions can access other values from the yaml, even if those are also $fn computed.
UI Informs of out of order $fn dependencies.
$fn execution is strictly defined (top to bottom, shallow to deep, aka depth first)
Errors in the yaml or functions don't interrupt plotting but are shown in the UI with intuitive phrasing.
...

The UI will let you know which plots are affected, how, and what to do.

no_theme: renamed to ha_theme (inverted logic)
no_default_layout: replaced with more general raw_plotly_config
offset: renamed to time_offset to avoid conflicts with bar-offset
lambda: removed, use filters instead
significant_changes_only: removed, it is now always set to false
minimal_response: removed, if you need attributes use the 'attribute' parameter instead.
show_value.right_margin: removed, the values are shown out of the plotting area. use time_offsets to make space for them
