Hi
I search to do a graph with 2 serie line :
- temperature = this year
- temperature = last year
I don't find how i can do this with Belchertown
Do you have an idea ?
King regards ! :)

If you are willing to get your hands dirty I came up with code to do this:
You just stick that in /usr/share/weewx/user/ assuming you installed from a deb file
In my case I'm using a modified Standard skin I put user.imagegenerator.ImageGenerator to replace the weewx standard ImageGenerator
From there you just do the following,
[[LastYear_images]]
x_label_format = %d/%m
bottom_label_format = %x %X
time_length = 31536000
aggregate_type = avg
aggregate_interval = 86400
show_daynight = false
previous_year = -1
[[[lastyearbarometer]]]
[[[[barometer]]]]
[[[lastyeartempdew]]]
[[[[outTemp]]]]
[[[[dewpoint]]]]
[[[lastyearhumidity]]]
[[[[outHumidity]]]]
# Daily high/lows:
[[[lastyearhilow]]]
[[[[hi]]]]
data_type = outTemp
aggregate_type = max
label = High
[[[[low]]]]
data_type = outTemp
aggregate_type = min
label = Low Temperature
[[[lastyearwind]]]
[[[[windSpeed]]]]
[[[[windGust]]]]
aggregate_type = max
[[[lastyeartempchill]]]
[[[[windchill]]]]
[[[[heatindex]]]]
[[[lastyearrain]]]
yscale = None, None, 0.02
plot_type = bar
[[[[rain]]]]
aggregate_type = sum
aggregate_interval = 604800
label = Rain (weekly total)
[[[lastyearwinddir]]]
yscale = 0.0, 360.0, 45.0
[[[[windDir]]]]
[[[lastyearradiation]]]
aggregate_type = max
[[[[radiation]]]]
[[[lastyearuv]]]
yscale = 0, 16, 1
aggregate_type = max
[[[[UV]]]]
