I’m having issues displaying text on a point in a graph when you hover over it in Processing4.I have tried using a loop to display the text but it seems the graph plot doesn’t allow anything display on it. I dont know what else to do I have tried using the GTooltip function in the G4P library.

Can you please show your code?

Do you use a library for the graph?
