Finally getting back to this, and this still does not work. It creates the
graph x and y axes and time stamps properly but doesn't seem able to read
the data.
[[chart6]]
title = Water level
data_binding = 'sdr_binding'
time_length = week
type = spline
[[[leafTemp2]]]
name = Water level
The sdr_binding works properly in the inex_hook_after_station_info.inc thus:
$latest($data_binding='sdr_binding').leafTemp2
I am puzzled.
