additional display of key pressure in the seasons skin

[Pline Pa]

After I started with weewx, I switched from the simulator to fileparse.

I use fileparse to read in the readings of my old ELV-weatherstation.
Via fileparse i read the station pressure.

In the standard skin i see the sea level (barometer) as declared under:
https://github.com/weewx/weewx/wiki/Barometer,-pressure,-and-altimeter

So that I can also see the key pressure, I have now made the following changes:

added in /etc/weewx/skins/Seasons/current.inc:

<tr>
<td class = "label"> $ obs.label.pressure </td>
<td class = "data"> $ current.pressure ($ trend.pressure.formatted) </td>
</tr>

added in /etc/weewx/skins/Seasons/skin.conf:

[Labels]
[[Generic]]
pressure = Pressure

The pressure value is displayed and no error messages can be seen in the log.

Did I proceed correctly or should I make the adjustment elsewhere?

Thank you for your knowledge and your patience with beginners like me!

The value for pressure is now additionally displayed on the left under "current conditions".

But how can I change the plot from barometer (sea level) to pressure (station level)?
