I should get the data from background and display in the line charts, about 10240 data should update each time, but it seems that redraw is very slow, the refresh code is like below

view.data?.notifyDataChanged()
view.notifyDataSetChanged()
view.setNeedsDisplay()

anything wrong with this code?

it will be slow for sure. Currently there is no better options but reduce your data sets by sampling.
