scroll - JavaFX horizontal list of charts -
i'm developing software comparison of different amounts of data , want use charts display them in horizontal way. important me display 3 charts on 1 side. if there more 3 user shall scroll other charts.
it won't pic, i'm lazy css. idea put charts in gridpane inside scrollpane. bind charts width 1/3 of tabpane width.
i used fxml since it's easier make scene.
fxmldocument.fxml
