Replace specific item types with generic DataItem

Using a generic DataItem allows to re-use the same data for different
chart types.

For charts that require two-dimensional data points (like LineChart),
add DataItem2D that adds an x value and use the super type's value as y.

LineChart can also use DataItem, in this case the x value will be the
index.
