I'm trying to implement a RecyclerView like diagram, which is
-infinite
-can scale along x and y, with respect to the center
-paginated, including EdgeEffect if no data
I have two options now:
Use RecyclerView and add portions of graph on it.
This leads me to an issue, that scaling along X axis is hard.
You need to scale the view, and then scroll the recyclerView back, so view would be centered
Another option is to prepare all the data and then draw only visible part on a canvas. But here I'm unable to precisely determinate the end of the each page (because there is no pages)
maybe you guys have some ideas
