Change type of access to fields in HighChartsSeriesImpl from default to protected

[SinigagliaSteeve]

Hi,

I wanted to create a new type of Series : SplineChartSeries for example, but when i extend HightChartsSeriesImpl i couldn't change the value of parent fields (name, chartType, data) because these attributes is only visible from the class in their package.

To create my own ChartSeries, i had to change the value of these field thank's to Reflection, and it's not confortable :)

Thank's for your answer.
Best regards
