Sets the chart area for the chart layer.
If the model is set before the chart layer is added to a chart area, series options will not be available. Setting the chart area will create the series options for the model in this case. Subclasses can extend this method to handle the new options.

Called when any of the series options are changed.
Default implementation fires the modelSeriesChanged() signal.
options | The options that fired the dataChanged() signal. |
type | Type of the option that was changed. |
newValue | The new value for the option. |
oldValue | The previous value for the option, if any. |
