Add Top n and Bottom n mode similar to auto-bin mode to axis selector
{noformat} The axis selector would benefit from having a Top n and Bottom n mode similar to the auto-bin mode. The mode would turn on a slider for the axis selector where I could decide how many top or bottom values I want to display on the axis.
I should also be able to select if the rest of the values should grouped in a category "Other" or not be visible.
