As the picture displayed below, I want to implement a coordinates.
The X coordinates represent something like time, and the Y coordinates represent percentage.
Now you maybe know that I want to show some data information which changes with time goes on.
Here is the question, There is not enough space on the Android screen to show all the data, so I want the user to view the information before/after by clicking buttons(such as <--, -->), OR, the user can just touch the screen and drag left/right to view more information.
I wonder what View or ViewGroup should I use for this case?
Thanks so much.
