java - no error then why ObservableList is not working in this project? -
i saw project in previous answer , tried run didn't how pass data parsed text file , insert values observablelist in javafx?
data inputted text file table view , piechart javafx, work except pie chart trying data table view pie chart, have done after few edits can't run anymore
the problem in observablelist piechartdata = fxcollections .observablearraylist()
this code

no problem observablelist piechartdata = fxcollections .observablearraylist() empty arrylist.
