r2494 Adds the \a series onto the chart and takes the ownership of it.
\note A newly added series is attached to no axes by default, including any axes that were created for the chart
using createDefaultAxes() before the series was added to the chart. If no axes are attached to
the newly added series before the chart is shown, the series will get drawn as if it had axes with ranges
that exactly fit the series to the plot area of the chart. This can be confusing if the same chart also displays other
series that have properly attached axes, so always make sure you either call createDefaultAxes() after
a series has been added or explicitly attach axes for the series.

r2494 \note This function has to be called after all series have been added to the chart. The axes created by this function
will NOT get automatically attached to any series added to the chart after this function has been called.
A series with no axes attached will by default scale to utilize the entire plot area of the chart, which can be confusing
if there are other series with properly attached axes also present.
