I tested and problem occurs in Delphi XE7 Enterprise too. You can test using the same attached test application source code. Confirmed. The problem happens when the colorgrid pen is visible, because the grid values aren't totally complete. There are grid cells missing. Disabling it is a workaround until the bug is fixed: lsOc.Pen.Hide; Fixed. The fix is at TeeSurfa.pas unit, DrawGrid procedure, there are two places:
if tmpGrid<0 then
begin
if Length(GridIndex[tmpIndex])>tmpIndex then // <----- This line
tmpGrid:=GridIndex[tmpIndex,tmpIndex];
if tmpGrid<0 then
tmpGrid:=0;
end;

Created attachment 438 [details] Bugreport generated by madExcept and source code of a simple test application Access violation occurs when I fill a TColorGridSeries using a DataSet. The trouble started after I update TeeChart 2010 to TeeChart 2015 in Delphi XE1 Pro. I made an application to simplify error case, removing all irrelevant elements. DataSet are involved in problem. I tested and problem occurs using TSimpleDataSet, TSQLQuery and TClientDataSet. I suppose problem occurs with any DataSet. Problem occurs at method DrawGrid in unit TeeSurfa. I attached a test application and the bugreport generated by madExcept. Thanks in advance Best regards.
