java - JavaFX lineChart issue -


i have following code:

 final treemap<integer, double> adlmap = new treemap<>();      public static void main(string[] args) {     launch(args); }    @override public void start(stage stage) {     final string currency = "currreny";     adl(currency);     stage.settitle("line chart sample");     //defining axes     final numberaxis xaxis = new numberaxis();     final numberaxis yaxis = new numberaxis();     xaxis.setlabel("number of month");     //creating chart     final linechart<number, number> linechart = new linechart<number, number>(xaxis, yaxis);     linechart.settitle("stock monitoring, 2010");     //defining series     xychart.series adlchart = new xychart.series();     xychart.series regularchart = new xychart.series();      adlchart.setname("my portfolio");      chartmap.entryset().foreach(entry -> regularchart.getdata().add(new xychart.data(entry.getkey(), entry.getvalue())));      //populating series data     adlmap.entryset().foreach(entry -> adlchart.getdata().add(new xychart.data(entry.getkey(), entry.getvalue())));     system.out.println(adlmap);     linechart.setcreatesymbols(false);      scene scene = new scene(linechart, 1200, 1000);     //linechart.getdata().add(regularchart);     linechart.getdata().add(adlchart);      stage.setscene(scene);     stage.show();       final double scale_delta = 1.1;     linechart.setonscroll(new eventhandler<scrollevent>() {         public void handle(scrollevent event) {             event.consume();              if (event.getdeltay() == 0) {                 return;             }              double scalefactor = (event.getdeltay() > 0) ? scale_delta : 1 / scale_delta;              linechart.setscalex(linechart.getscalex() * scalefactor);             linechart.setscaley(linechart.getscaley() * scalefactor);         }     });      linechart.setonmousepressed(new eventhandler<mouseevent>() {         public void handle(mouseevent event) {             if (event.getclickcount() == 2) {                 linechart.setscalex(1.0);                 linechart.setscaley(1.0);             }         }     });  }     private void adl(final string currency) {     double counter = -4000000.0;     int mapcounter = 0;     while (counter < 4000000) {         adlmap.put(mapcounter++, counter++);     } }

the map contains following values: keys n+1 n€in values range -10.000.000 + 10.000.000

my problem: doesn't plot values @ all. @ least cannot see any.

can please help?

my mistake complex algorithm produced inifnity nuber placed in treemap. graph couldn't plot ofc.
