What unit do i need to give a sensor for the history graph to show a graph?

Hi folks, i have a sensor, that does not really have a unit other than pieces.

so currently i have not given the sensor a unit of measurement, however its not a state its a logic number. so what unit should i take to make it show a graph and not a bar in lovelace?

currently I use the graph: line card but I dont like that card… would like to go back to the history graph.

give it whatever units you want. If it has units, it’s assumed a number. It can be anything, e.g. forks
