java - How to perform big numbers on axis (for example, 10^3 format) in chart? -


using big space performing long numbers not decision. if have graph medium scale 50 000, on y axis written "50 000, 60 000, 10 000". can perform there 50 * 10^3 or else? it's necessary charts several scales here

use ticklabelformatter on axis. example:

    numberformat format = new decimalformat("#.#e0");     yaxis.setticklabelformatter(new stringconverter<number>() {          @override         public string tostring(number number) {             return format.format(number.doublevalue());         }          @override         public number fromstring(string string) {             try {                 return format.parse(string);             } catch (parseexception e) {                 e.printstacktrace();                 return 0 ;             }         }      });

complete example:

import java.text.decimalformat; import java.text.numberformat; import java.text.parseexception;  import javafx.application.application; import javafx.scene.scene; import javafx.scene.chart.linechart; import javafx.scene.chart.numberaxis; import javafx.scene.chart.xychart; import javafx.stage.stage; import javafx.util.stringconverter;  public class linechartwithformattednumbers extends application {      @override     public void start(stage primarystage) {         final numberaxis xaxis = new numberaxis();         final numberaxis yaxis = new numberaxis();          numberformat format = new decimalformat("#.#e0");         yaxis.setticklabelformatter(new stringconverter<number>() {              @override             public string tostring(number number) {                 return format.format(number.doublevalue());             }              @override             public number fromstring(string string) {                 try {                     return format.parse(string);                 } catch (parseexception e) {                     e.printstacktrace();                     return 0 ;                 }             }          });          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<number, number> series = new xychart.series<>();         series.setname("my portfolio");         //populating series data         series.getdata().add(new xychart.data<>(1, 23e10));         series.getdata().add(new xychart.data<>(2, 14e9));         series.getdata().add(new xychart.data<>(3, 15e10));         series.getdata().add(new xychart.data<>(4, 24e9));         series.getdata().add(new xychart.data<>(5, 34e10));         series.getdata().add(new xychart.data<>(6, 36e10));         series.getdata().add(new xychart.data<>(7, 22e10));         series.getdata().add(new xychart.data<>(8, 45e10));         series.getdata().add(new xychart.data<>(9, 43e10));         series.getdata().add(new xychart.data<>(10, 17e10));         series.getdata().add(new xychart.data<>(11, 29e10));         series.getdata().add(new xychart.data<>(12, 25e10));          scene scene  = new scene(linechart,800,600);         linechart.getdata().add(series);          primarystage.setscene(scene);         primarystage.show();     }      public static void main(string[] args) {         launch(args);     } }

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
