Sorry for the inconvenience caused. We have renamed the ‘OlapChart’ control as ‘PivotChart’, so please change the class name for creating Pivotchart instance as following.
PivotChart htmlHelper = new PivotChart();
Meanwhile, we will update the online document in the upcoming 2016 Volume3 release, which will be rolled out at the mid of September 2016.
Please let us know if you have any concern.
