HIGHCHARTS CORE v4.2.0 CHANGES
These core changes also apply to this moduleEXPANDCOLLAPSE
Included the Standalone Framework in Highcharts and removed the concept of adapters.
Removed global properties in Highcharts and modules. Closes #4389.
Added new constructor, Highcharts.chart, that allows instanciating a chart without the new keyword.
Added an option to set the renderTo div as the first argument to the constructor, like Highcharts.chart(renderTo, options);.
Added support for fill-opacity and stroke-opacity attributes on VML renderer. Support semi-transparent fill with named colors on area series.
Breaking change: Easing functions from jQuery UI no longer work. They will fall back to the default “swing” easing. With Highcharts 4.2, the easing function must be defined on the Math object itself.
Breaking change: The sparkline demo has some changes in the constructor.
