bug: state: last and graph: bar breaks graph rendering #736
Description
I have always increasing sensors for internet upload and download and I'm trying to make an hourly upload and download bar graph. Everything works great except I'm trying to have the latest graph values show for the state rather than the actual sensor state values (as they are meaningless ... total upload and download since last router reboot). If I change the show > state to true or false, everything is fine; it doesn't seem to like 'last' although that is the setting according to the docs which will render what I'm looking for.
I'm on the latest version of HA (2022.2.8), HACS, and the mini graph card.

This image is with the show > state set to true and everything looks good except the sensor states are showing.
