I went through the question
how to display bar value on top of bar javafx
I tried the same code with data refresh. The text seems to stay, once the data is refreshed. I tried to remove the text once added, but received no success as there is no way to get through the parent before XYSeries object is populated !
If you go through the following link, I have modified the code and kept a refresh button at the bottom. On pressing it, the chart gets new values, but the old Text stays. Is there a way to remove it, before new values are supplied to the chart
