Add proper 'deprecated' warnings

Use Q_DECL_DEPRECATED to mark deprecated API. Fix examples to do
not use deprecated functions.

These functions were 'marked' as deprecated when multiple axes
were introduced. Moreover, axis X/Y is an ambiguous term and not necessary
mean Horizontal/Vertical axis. These deprecated methods also create an
issue when given series should be attached to several Horizonal/
Vertical axes and calling them can cause unwanted results.
