Please take a look at my code and give me some ideas on how
to fix the bug.
An animation LineChart ex.,i used ArrayCollection but the
chart can not be changed when i choose the first item in
Combobox,the second and the third have no problem.In my
ChangeData() function,the expensesData1(an ArrayCollection) got
data which has been changed before,so chart couldn't be redrawn.
Please help me to solve this problem,thanks
