OnGetAxisLabel even handler causes wrong height of horizontal axis title - there is an obvious problem in a new code in the TChartAxis.InternalCalcSize function.

I attached an example reproducing this problem. If you remove empty even handler - plotting reverts to normal.

Fixed. There was an oversight, sorry. 
New code at InternalCalcSize should be:

    if Assigned(ParentChart.FOnGetAxisLabel) then
       tmpHeight:=Horizontal  // <---- FIXED BUG 
    else
       tmpHeight:=( Horizontal and ((tmpAngle=0) or (tmpAngle=180))) or
                  ( (not Horizontal) and ((tmpAngle=90) or (tmpAngle=270)));
