A new, default ChartArea is added if one does not exist, otherwise chart.ChartAreas[0] is used. Axis titles, and DefaultAxisTitleFont and DefaultMajorGridLineColor, only have an effect if a new ChartArea is added.
Titles are added only if chart does not currently contain any titles.
The first two data series are replaced, or added if necessary.
