I would like to show my pv energy by year:
[eyear]
show_button = true
button_text = "Jahr"
title = "Jahr"
time_length = year
tooltip_date_format = "LLLL"
gapsize = 2678400000 # 31 Tage in [ms]
yAxis_label = "Energie"
start_at_midnight = true
start_at_beginning_of_month = true
xAxis_groupby = month
xAxis_categories = 'Jan', 'Feb', 'Mar', 'Apr', 'Mai', 'Jun', 'Jul',
'Aug', 'Sep', 'Okt', 'Nov', 'Dez'
[[energy_plt]]
title = "Energie"
[[[pv_day_wh]]]
name = PV
color = "#ffc83f"
type = column
unit = kilowatt_hour
[[energy1_plt]]
title = "Energie 2021 [A]"
year_specific = 2021
[[[pv_day_wh]]]
name = PV
color = "#ffc83f"
type = column
unit = kilowatt_hour
[[energy2_plt]]
title = "Energie 2021 [B]"
time_length = years_ago
time_ago = 1
[[[pv_day_wh]]]
name = PV
color = "#ffc83f"
type = column
unit = kilowatt_hour

The chart [A] is correct, but i had to use ' year_specific = 2021 '. Chart
[B] is using ' time_length = years_ago ' and it seems, that this chart is
collecting all data from every month in the path and not only from 2021.
I would like to use ' time_length = years_ago ' for this chart. Any idea
how ?
Regards
Matthias
