Recover calculator inputs from a saved graph?
Title may be misleading. Sorry about that.
Anyway, the issue at hand is that I plotted a graph of some differential equations using the browser-based calculator a few days ago. Saved it as an activity intending to go back to it later in case I needed to make changes, but now I can't access the input section on the left where I entered all my data.
Is that all just lost, or is there a way to open that interface? Was there a setting I should have ticked when I saved the graph to preserve that data? Do I have to try to recreate the entire thing from scratch?
