JAVAFX LineChart隐藏/显示行

Question

Is it possible to show/hide certain lines in a linechart by click on the legend or does it have to be implemented manually?

Sincerely.

Maybe each line can be a serie, and then you can alter the select line using css. I used it to change the color of the selected data from a table view.

 table.getSelectionModel() .selectedIndexProperty() .addListener((observable, oldValue, newValue) -> colorPeak(oldValue, newValue)); public void colorPeak(Number oldV, Number newV) { if (oldV.intValue() != -1) { lineChart.getData().get(oldV.intValue()).getNode().setId("serie-unselect"); } if (newV.intValue() != -1) { lineChart.getData().get(newV.intValue()).getNode().setId("serie-select"); } } 

 #serie-unselect { -fx-stroke: blue; } #serie-select { -fx-stroke: //color of the background }
