Proper GUI Design for Mobile App to Indicate Swipeable View

So we're working on a mobile app for android/ios that has a screen displaying a chart. We need to display 2 charts that have display different data. We agreed on displaying each chart on its own view which a user can swipe to view them. To indicate that the screen can be swiped, we placed a caret image pointing to the right or the left to indicate where it can be swiped to.

I have two questions regarding this:

  1. Was our choice of using a < and > symbol to indicate the screen can be swiped ok?
  2. If 1 is ok, would it be better if there was a label below it stating what it would display or would it be better without a label?
