i am currently plotting data on a graph from a physical system. However when i want to add new data to the plot, the old one is replaced. I am trying to do more than one plot on the same graph, where the incoming data is at different times. I want something like Excel where i can just add a new plot to the graph.Can i save the data or freeze it onto the graph or something so that i can add a new plot and see the two at the same time?
