I find myself the answer in the userguide :
Including the same SQL type more than once in a plot
Another example. Say you want a plot of the day's temperature, overlaid
with hourly averages. Here, you are using the same data type (outTemp) for
both plot lines, the first with averages, the second without. If you do the
obvious it won't work:
## WRONG ##
[[[daytemp_with_avg]]]
[[[[outTemp]]]]
aggregate_type = avg
aggregate_interval = 3600
[[[[outTemp]]]] # OOPS! The same section name appears more than once!
The option parser does not allow the same section name (outTemp in this
case) to appear more than once at a given level in the configuration file,
so an error will be declared (technical reason: formally, the sections are
an unordered dictionary). If you wish for the same SQL type to appear more
than once in a plot then there is a trick you must know: use option
data_type. This will override the default action that the logical line name
is used for the SQL type. So, our example would look like this:
[[[daytemp_with_avg]]]
[[[[avgTemp]]]]
data_type = outTemp
aggregate_type = avg
aggregate_interval = 3600
label = Avg. Temp.
[[[[outTemp]]]]
