I have a BarChart that needs to have horizontal lines at two points on the
x-axis (like show "average score"). I accomplished this by adding a LineSeries
for each score. Each LineSeries has two points, with the x values identical,
and the y values set to min and max (thus creating a horizontal line).

The problem is that when I add the LineSeries the bar height gets reduced to
one third (as if there were two more BarSeries that neede to share the chart
item space. Does any one have any idea how I can prevent this? Or a better way
to accomplish adding my horizontal lines?

Furthermore, I have never been able to explicitly set the bar height. When I
do so it is always ignored.

Please see my examples:

I've attached the MXML for the BarChart and my my HorizontalLineSeries
component.

Thank You :lips;
