'Total cost saving chart' displays lines only back 10 days.

[SwiftRR]

Describe the bug The 'Total cost saving chart' displays lines only back 10 days. Bizarrely, neither line starts at 10 days back. I don't know when this behaviour started but previously I could see lines tracking back 29 days as in the yaml. This is the current chart display.

If I change the graph span and offset to 10/9, the displayed chart starts 10 days ago but the start values are not zero. It is almost as if they are projecting back 30/29 days.

I have tried increasing the graph span and offset for the related 'Daily cost saving chart' and this also displays back for 10 days.

Is this a reflection of HA saved historical data?

Expected behavior Chart display going back 29/30 days as in yaml. The yaml code is copied directly from https://github.com/springfall2008/batpred/blob/main/templates/example_chart.yml

Predbat version v8.3.1 on predbat standalone (v1.1.8) with no appdaemon.

Environment details

• GE AC3.0 inverter to two 8.2 kWh batteries
• HAOS 2024.6.4 on Raspberry pi4 with ssd
• Chart display tested on Mac OSX 17.5 (Safari and Chrome) and HA app on iPad. Same behaviour on all.

I believe this is due to the homeassistant limitation on historical data.

This can be adjusted using: https://www.home-assistant.io/integrations/recorder/#purge_keep_days

I have mine set to a month and my chart shows the full month correctly.
