Jerry,
Been a while since I have touched this one, and I note there is a dead link
in the weewx-highcharts wiki for changing the plot units - guess I should
fix that.
Anyway, you should be able to change the units used in the json file via
weewx.conf - it's not a US/Metric switch but rather a config option for
each unit group . If you have a look at the [StdReport] stanza in weewx.conf
you should have a [[Highcharts]] [[[Units]]] [[[[Groups]]]] stanza that
will probably look something like:
[StdReport]
....
[[Highcharts]]
....
[[[Units]]]
....
[[[[Groups]]]]
group_altitude = meter
group_degree_day = degree_C_day
group_pressure = hPa
group_rain = mm
group_rainrate = mm_per_hour
group_speed = km_per_hour
group_speed2 = km_per_hour2
group_temperature = degree_C
Change the group_xxxx option settings as required. The values are standard
WeeWX unit group names as per the Group column in the Unit groups, members
and options table in the Units appendix to the Customization Guide
<http://weewx.com/docs/customizing.htm#units>. There may be some stale_age
settings that could delay re-generation of the json files, just delete the
json output files on your WeeWX machine to force regeneration on the next
report cycle.
A bit pressed for time so have not had a change to test this, if the above
does not work could you please post your [StdReport] stanza and I will have
a closer look.
