Graph from values in yaml?

[fcassirer]

I was wondering if there was any way to use an alternate data source for the history values for a mini-graph-card. The use case is that I have a json data blob for xfinity usage. The blob has a usage value which I bring in via an mqtt sensor declaration, but it also has attributes that contain an array of 5 or 6 of the past months total usage.

I am trying to determine how I could create a (bar) graph of the 6 past months values and the usage so far this month. I could imagine a graph declaration that looked like:

type: 'custom:mini-graph-card'
entities:
  - entity: sensor.xfinity_usage
custom_data:
  - value: {{ sensor.xfinity_monthly_usage.attributes.raw.usageData[0].totalUsage }}
    created: {{ as_timestamp(sensor.xfinity_monthly_usage.attributes.raw.usageData[0].endDate) }}
  - value: {{ sensor.xfinity_monthly_usage.attributes.raw.usageData[1].totalUsage }}
    created: {{ as_timestamp(sensor.xfinity_monthly_usage.attributes.raw.usageData[1].endDate) }}
  - value: {{ sensor.xfinity_monthly_usage.attributes.raw.usageData[2].totalUsage }}
    created: {{ as_timestamp(sensor.xfinity_monthly_usage.attributes.raw.usageData[2].endDate) }}
  - value: {{ sensor.xfinity_monthly_usage.attributes.raw.usageData[3].totalUsage }}
    created: {{ as_timestamp(sensor.xfinity_monthly_usage.attributes.raw.usageData[3].endDate) }}
  - value: {{ sensor.xfinity_monthly_usage.attributes.raw.usageData[4].totalUsage }}
    created: {{ as_timestamp(sensor.xfinity_monthly_usage.attributes.raw.usageData[4].endDate) }}

Obviously the value/created hash could be generated by jinja, but I hardcoded it here for illustration.

The result of this would be to graph the current value of the sensor 'xfinity_usage' which is the running total and then use the data values as previous bars based on the date provided. Likely the custom_data might need to be tied to a given entity so maybe it needs to indent custom_data under entity, but hopefully this gets the idea across.

Thoughts? Are there other ways to accomplish this?

Thanks in advance for any insight.

You can do that using data_generator from the alternative apexcharts-card. https://github.com/RomRider/apexcharts-card

@RomRider thank you! That is exactly what I was looking for. I was able to cobble something together using the bar-card and a bunch of sensor templates, but this is a much better option.
