java - Line chart symbols clipped by axis when they lie on the axis -

i have line chart defined axis range, , plotting points part of line lie on axis. default points , line segments lie on axis clipped, shown in below screen shot;

my code below;

package com.jtech;  import javafx.application.application; import javafx.event.eventhandler; import javafx.scene.node; import javafx.scene.scene; import javafx.scene.chart.axis; import javafx.scene.chart.linechart; import javafx.scene.chart.numberaxis; import javafx.scene.chart.xychart; import javafx.scene.input.mouseevent; import javafx.stage.stage;  public class showsymbol extends application {      @override     public void start(stage stage) {         final numberaxis xaxis = new numberaxis(0,4,1);         final numberaxis yaxis = new numberaxis(0,10,2);          final linechart<number, number> linechart = new linechart<>(xaxis, yaxis);         xychart.series series = new xychart.series();      final xychart.data d1 = new xychart.data(0.0, 0.0);     final xychart.data d2 = new xychart.data(0.5, 2.0);     final xychart.data d3 = new xychart.data(1.0, 2.5);     final xychart.data d4 = new xychart.data(1.5, 3.5);     final xychart.data d5 = new xychart.data(2.0, 10.0);     final xychart.data d6 = new xychart.data(2.5, 10.0);     final xychart.data d7 = new xychart.data(3.0, 0.0);     final xychart.data d8 = new xychart.data(3.5, 0.0);     final xychart.data d9 = new xychart.data(4.0, 8.0);          series.getdata().addall(d1,d2,d3,d4,d5,d6,d7,d8,d9);         linechart.getdata().add(series);         linechart.setlegendvisible(false);          final scene scene = new scene(linechart, 400, 300);         scene.getstylesheets().add(getclass().getresource("/css/show.css").toexternalform());          stage.setscene(scene);         stage.show();     }       public static void main(string[] args) {         launch(args);     } }   

where style sheet contains;

.chart-series-line { -fx-stroke: grey; -fx-stroke-width: 4.0px; -fx-effect: null; }  .chart-line-symbol {      -fx-background-color: #860061, white;      -fx-background-insets: 0, 2;      -fx-background-radius: 0;      -fx-padding: 4px;  } 

i keep axis range specified (0->4 , 0->10), show complete segments of symbols , lines lie on them. possible?

the problem facing plot area clipped. code excerpt xychart.java:

private final group plotarea = new group(){   @override public void requestlayout() {} // suppress layout requests }; private final group plotcontent = new group(); private final rectangle plotareaclip = new rectangle();  public xychart(axis<x> xaxis, axis<y> yaxis) { ... getchartchildren().addall(plotbackground,plotarea,xaxis,yaxis); ... plotarea.setclip(plotareaclip); ... } 

a solution might disable clip. give other troubles (line overlapping, etc). nontheless, since there no proper api this, here's quick & dirty way how disable clipping:

region chartcontent = (region) linechart.lookup(".chart-content"); for( node node: chartcontent.getchildrenunmodifiable()) {     if( node instanceof group) {         group plotarea= (group) node;         plotarea.setclip(null);     } } 

it'll then:

bottom line: you're better off implementing own chart (e. g. use , change source of linechart , xychart) supports feature. or file change request proper solution.
