我有一个程序，它将数据输入到一个表中，计算其他数据，然后再绘制它。表格和数据正确显示，但线图没有显示任何内容。我使用JavaFXML应用程序和scenebuilder。 PS：我是JAVA新手。图不显示

应该像你看起来对我来说''handleButtonAction（...）'方法中有'ArrayIndexOutOfBoundsException'。有没有错误信息？ –

@James_D没有错误信息 –

我运行了它，但是我不知道要输入什么数字。图表显示了一些东西，但是因为这些值没有意义，所以没有多少值得注意的地方。对于'LineChart'，你真的希望数据按照'x'值的顺序。如果您只是在该方法中绘制一些固定数据，您是否看到图表中的任何内容？ –

您的一个数据点，是给NaN x值，这是造成自动范围数轴的失败。你可以看到这一点，如果你在你的按钮操作方法提供一些记录：

for(int i=0; i<9; i++) 
{ 

    XYChart.Data<Number, Number> dataPoint = new XYChart.Data<>(Math.log10(s[i]), Math.log10(us[i])); 
    System.out.println("("+dataPoint.getXValue()+", "+dataPoint.getYValue()+")"); 
    graph.getData().add(dataPoint); 
}

您可以通过添加到图表之前检查值修复该问题：

for(int i=0; i<9; i++) 
{ 

    XYChart.Data<Number, Number> dataPoint = new XYChart.Data<>(Math.log10(s[i]), Math.log10(us[i])); 
    System.out.println("("+dataPoint.getXValue()+", "+dataPoint.getYValue()+")"); 
    if (Double.isFinite(dataPoint.getXValue().doubleValue())) { 
     graph.getData().add(dataPoint); 
    } 
}
