[Bug]: when values donot change, the graph shows null (or zero?)

[vingerha]

1. Is it related to Long Term Statistics (LTS)?

No

1a. If it is related to Long Term Statistics (LTS) then please attach your CSV file(s) of entities

I did

2. Your YAML Code

type: custom:statistics-graph-chart-card
hours_to_show: 24
auto_scale_points: false
height: 300
graph_start_hour: 1
show_full_period: true
entities:
  - entity: sensor.linky_energy_hphc_daily
    offset: 24
    color: "#e8926d"
    y_axis: primary
    graph_type: bar
    aggregate_func: state

3. Bug Description

My energy consumption frm the net is 0 at times when I produce more solar energy. So at that time the value of the consumed energy (total increasing) is not changing. There are omitted from the graph.

Hi,

Is this related with latest release? Which release is the latest working?

[vingerha]

Yeah, apologies.... more data is helpful... v2.20 was the last one, after that also the group_by: hour started acting up too.
I was a bit busy so could not test or repsond to all the releases at your speed ... so hoped it would resolve itself without me reporting an issue :)

What I now notice in v2.20 is that the in-between equal values are omitted but graph-ending figures are not (which should be the case)

V2.2.0:
Wrong: The last 3 colums are invented as not present in the system

Good The in-between equal figires are show,

V.2.2.9
Good: non-available values not shown

Wrong: in-between euqal figures not shown

I think when a sensor is unavailable the returned value should be null, but if it doesn't change it needs to return just "0".
Right?

[vingerha]

if not in the system it should be null or 0 ... at least not shown as a value higher than 0 as this is misleading
For non-changing, in my example it is a total increasing, and it is not 0 in the sysem, it has the same value as the previous hour/period LTS so should be shown as such. Context on the last picture, this is my elec consumption from the net which as 'power' went 0 when my panels produced more but as 'energy' it remains flat/unchanged.
