How to reset graphs at 12 midnight?

As a graph is "resetted" each time you pass new data to it, i am not sure on how to understand this question.... or are you talking about a "chart"?

Pass an empty array of the correct format via a property node_history data.

 rigth click on the chart icon, create property node (last entry is history data) , change all to write, rigth click - create constant

and the snippet changed the property 😕
