The Thistle::AbstractAxis class provides an abstract base for every charts axis.
The Thistle::AbstractAxis class provides the basic functionality for every axis. It is a abstract class and cannot be instancied itself. Thistle::AbstractAxis provides a standard interface to define item position and axis painting. It reimplements basic logic for positionning items in the view.
| void calculateBounds | ( | ) |
Calculates the model data bounds.
Calculates the min() bounds and the max() bounds (i.e., the min() and the max() displayed on the chart). Calculates the order() and the tick size(delta between two ticks on the Y axis) of the charts values. If the min() is equal to the max(), the minBound() is equal to min() - 1 and the maxBound() to max() + 1

Sets the QAbstractItemModel to use.
The model should be the same than the chart view.
