i am facing the same problem, when the data from database is very less in count then Fusion chart is not functioning well. to cover the height we given while chart is initializing, it repeating the vaules across y-axis.
see below figure for more details.
When data is more than 4 then only it is showing distinct vaules. If data is 1,2,3 then it is repeating vaules across y-axis.
please help me out.
thanks
