JavaScript Custom Color Theme ChartXY

Example on creating a Custom Color Theme for a simple ChartXY.

This does not contain a complete color theme, only the properties which are present in this particular chart application are specified for simplicity.

The Custom theme is created by overriding select properties of a default theme, the lightNew Theme specifically.

Custom themes are a good option to styling each component at a time, especially as custom themes can be much more easily shared between different charts or applications.
