I think if you added an API for changing the window of the graph it'd make this package a lot more popular(especially with me).
When we're calculating/graphing often we go far away from (0,0). Not being able to resize this programmatically after a user enters an equation for example limits what's possible with graph_calculator.
Some examples of what I mean are these calculus business optimization problems here.
I hope to use this package but if I can't figure out how to do it I'll have to use a WebView with some JS libraries that implement that feature.
Hope that makes sense and it isn't a heavy lift for you. Thanks for your work so much already!
