["Yulin Wang" <yulin.wang@xxxxxxxxxxx>]

- Summary:
"Show Lines as Curves" does not work correctly for Bubble and Difference Chart with null values [0001]

- Bugzilla Bug (s) Resolved:
184554

- Description:
Revised the logic of null handler in CurveRenderer.
Now CurveRenderer will use series renderer's method to handle null values, and that method can be overridden for specific series. For bug#176582, Area renderer will replace null by minimum values, and other renderers will skip the null.
