Second Y-axis remains visible even after removing references and layout

[sofkaski]

Describe the bug
Sequence:

1. I made a graph showing statistics on entities and using both primary and secondary Y-axis.
2. After some trials I decided to split the graph so that I would not use any more the secondary Y-axis.
3. I removed all references to secondary Y-axis and also the layout definition
4. Secondary Y axis is still visible. Browser deep refresh with cache clear does not help.

Additional context

Removed secondary Y-axis is visible also when viewing the card in the companion app in Android phone.

That's because inverter_today_battery_charge has a different unit_of_measurement than the power ones, so this card puts them in a second y axis.

You can force them to use y1 with yaxis: y, although you wouldn't be able to see those traces since their range is 3 orders of magnitude smaller than that of the other entities.

If you want them to use the second yaxis but not show the axis itself, then google/gpt "how to hide yaxis2 in pltly js"

Ah.. right. I did not pay attention that there was kWh and W. I think I picked wrong entities for the battery.

Closing.
