dinamically calculate array for tickvals (=== no x values for non interesting y values)

[luissimoes]

the case is a graph like the one below.
I just want to show the days where my EV was charged... and typically those are days where the energy is >= 10kWh
I have the chart, but for this to be good I want the x values to only show on those days.

My idea is to do this through tickvals.
So for this, would need to assign an array of XS values under the condition:

iy>10 => tickArray[ i ] = xs.at(i)

I couldn't add an fn function to tickvals....

any hint please?

I filtered the y values using

  - filter: y > 10

Something along these lines may work. I haven't tried this before, so you may have to fix it up :)

entities:
  - entity: sensor.xyz
  - entity: sensor.xyz
    Internal: true
    filters:
       - filter: y>10
       - store_var: xyz
layout:
   xaxis:
      tickvals: $ex vars.xyz.xs

yep, I had tried something similar but always got a similar error: "undefined is not an object" (see picture)

I tried to see the console... but I have no idea what it is doing and what it means.... :-( :-(...
From the Plotly description it seems tickvals wants an array (and I did try with explicit individual dates and it works) ... and XS as far as I understand is an array.... but seems that there is an object wrapper that is not recognised??

You need to put the layout below the entities. Execution is top to bottom
