如何使用XChart在Y轴上限制是相同的？ [英] How to make limits on the Y axis be the same using XChart?

问题描述

我试图绘制一系列类似的函数。域是[0,1]，范围总是在[-3,3]。

我想要Y轴上的限制是相同的图形。尝试设置系列y min和y max似乎不起作用。

有没有办法使每个图上的Y轴上的限制相同？

  import java.math.BigDecimal; 
 import java.util。*; 
 import com.xeiam.xchart。*; 
 public class Bug {
 static void plot（Chart chart，int n）{
 chart.setTitle（title）; 
 chart.setXAxisTitle（X）; 
 chart.setYAxisTitle（Y）; 
 List< Number> x = new ArrayList< Number>（）; 
 List< Number> y = new ArrayList< Number>（）; 
 String seriesName = addOneSeries（chart，n，x，y）; 
} 
 private static String addOneSeries（Chart chart，int n，List< Number> x，List< Number> y）{
 for（int i = 0; i <= 10; i ++ ）{
 x.add（i / 10。）; 
 y.add（i * n / 10。）; 
} 
 String seriesName =series+ n; 
系列系列= chart.addSeries（seriesName，x，y）; 
 series.xMin = BigDecimal.ZERO; 
 series.xMax = BigDecimal.ONE; 
 series.yMin = new BigDecimal（-5）; 
 series.yMax = new BigDecimal（5）; 
 return seriesName; 
} 
 public static void main（String [] args）{
 for（int i = 0; i <4; i ++）{
图表chart = ; 
 plot（chart，i）; 
 new SwingWrapper（chart）.displayChart（）; 
} 
} 
}

现在可以使用图表上的最小值和最大值nofollow> XChart 。下面是一个OP的Bug类的重做，演示了这一点。在这一刻，由于它是一个全新的功能，你必须得到一个xchart-2.0.0-SNAPSHOT jar 此处，以便查看此功能。请随时寻求帮助或请求更多功能！

  public class NoBug {
 
 static void plot（Chart chart，int n）{
 
 chart.setChartTitle（title）; 
 chart.setXAxisTitle（X）; 
 chart.setYAxisTitle（Y）; 
 List< Number> x = new ArrayList< Number>（）; 
 List< Number> y = new ArrayList< Number>（）; 
 String seriesName = addOneSeries（chart，n，x，y）; 
} 
 
 private static String addOneSeries（Chart chart，int n，List< Number> x，List< Number> y）{
 
 for（int i = 0; i <= 10; i ++）{
 x.add（i / 10）; 
 y.add（i * n / 10.）; 
} 
 String seriesName =series+ n; 
系列系列= chart.addSeries（seriesName，x，y）; 
 chart.getStyleManager（）。setxAxisMin（0）; 
 chart.getStyleManager（）。setxAxisMax（1）; 
 chart.getStyleManager（）。setyAxisMin（-5）; 
 chart.getStyleManager（）。setyAxisMax（5）; 
 return seriesName; 
} 
 
 public static void main（String [] args）{
 
 for（int i = 0; i <4; i ++）{
 Chart chart = new LineChart（700，500）; 
 plot（chart，i）; 
 new SwingWrapper（chart）.displayChart（）; 
} 
} 
 
} 
  

I am trying to plot a series of functions that are similar. The domain is [0,1] and the range always in say [-3,3].

I want the limits on the Y axis to be the same for each graph. Trying to set the series y min and y max does not seem to work.

Is there a way to make the limits on the Y axis be the same on each graph?

import java.math.BigDecimal;
import java.util.*;
import com.xeiam.xchart.*;
public class Bug {
    static void plot(Chart chart,int n) {
        chart.setTitle("title");
        chart.setXAxisTitle("X");
        chart.setYAxisTitle("Y");
        List<Number> x=new ArrayList<Number>();
        List<Number> y=new ArrayList<Number>();
        String seriesName=addOneSeries(chart,n,x,y);
    }
    private static String addOneSeries(Chart chart,int n,List<Number> x,List<Number> y) {
        for(int i=0;i<=10;i++) {
            x.add(i/10.);
            y.add(i*n/10.);
        }
        String seriesName="series "+n;
        Series series=chart.addSeries(seriesName,x,y);
        series.xMin=BigDecimal.ZERO;
        series.xMax=BigDecimal.ONE;
        series.yMin=new BigDecimal(-5);
        series.yMax=new BigDecimal(5);
        return seriesName;
    }
    public static void main(String[] args) {
        for(int i=0;i<4;i++) {
            Chart chart=new Chart(700,500);
            plot(chart,i);
            new SwingWrapper(chart).displayChart();
        }
    }
}

解决方案

Setting the min and max values on a Chart is now possible with XChart. Below is a rework of OP's Bug class that demonstrates this. At this moment, since it's a brand new feature, you'll have to get an xchart-2.0.0-SNAPSHOT jar here in order to see this capability. Please feel free to ask for help or request more features!

public class NoBug {

  static void plot(Chart chart, int n) {

    chart.setChartTitle("title");
    chart.setXAxisTitle("X");
    chart.setYAxisTitle("Y");
    List<Number> x = new ArrayList<Number>();
    List<Number> y = new ArrayList<Number>();
    String seriesName = addOneSeries(chart, n, x, y);
  }

  private static String addOneSeries(Chart chart, int n, List<Number> x, List<Number> y) {

    for (int i = 0; i <= 10; i++) {
      x.add(i / 10.);
      y.add(i * n / 10.);
    }
    String seriesName = "series " + n;
    Series series = chart.addSeries(seriesName, x, y);
    chart.getStyleManager().setxAxisMin(0);
    chart.getStyleManager().setxAxisMax(1);
    chart.getStyleManager().setyAxisMin(-5);
    chart.getStyleManager().setyAxisMax(5);
    return seriesName;
  }

  public static void main(String[] args) {

    for (int i = 0; i < 4; i++) {
      Chart chart = new LineChart(700, 500);
      plot(chart, i);
      new SwingWrapper(chart).displayChart();
    }
  }

}
