------------------------------------------

             Summary: CartesianChart renders an extra axis when a chart is created with no
axis and then some axis are added later
                 Key: FLEX-33141
                 URL: https://issues.apache.org/jira/browse/FLEX-33141
             Project: Apache Flex
          Issue Type: Bug
          Components: Charts:Multiple Axes
    Affects Versions: Adobe Flex SDK 4.5 (Release)
         Environment: Mac OS X
            Reporter: Gareth Daniel Smith
            Priority: Minor


I have a use-case where a LineChart is created with series=[] and then later on, after the
chart has been displayed to the user, the series changed to be non-empty. Essentially I have
a GUI that shows a user an empty chart and then allows the user to add series to it.

When the chart is created without any series then a default axis is shown. This is OK. The
issue is that this default axis does not go away when some real series (with their associated
axis) are added to the chart.

I think this happens because of the first few lines in CartesianChart.commitProperties which
create default horizontal/vertical axisRenderers if there are none in the user-supplied horizontal/vertical
axisRenderers array. I think the problem is that horizontalAxisRenderer/verticalAxisRenderer
never get set back to null when the user-supplied axis renderers arrays are changed to be
none-empty.
