本文整理了Java中org.jfree.chart.JFreeChart类的一些代码示例，展示了JFreeChart类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。JFreeChart类的具体详情如下：
包路径：org.jfree.chart.JFreeChart
类名称：JFreeChart

JFreeChart介绍

[英]A chart class implemented using the Java 2D APIs. The current version supports bar charts, line charts, pie charts and xy plots (including time series data).

JFreeChart coordinates several objects to achieve its aim of being able to draw a chart on a Java 2D graphics device: a list of Title objects (which often includes the chart's legend), a Plot and a org.jfree.data.general.Dataset (the plot in turn manages a domain axis and a range axis).

You should use a ChartPanel to display a chart in a GUI.

The ChartFactory class contains static methods for creating 'ready-made' charts.
[中]使用Java2D API实现的图表类。当前版本支持条形图、折线图、饼图和xy图（包括时间序列数据）。
JFreeChart协调多个对象以实现在Java 2D图形设备上绘制图表的目标：标题对象列表（通常包括图表的图例）、绘图和组织。jfree。数据全体的数据集（绘图依次管理域轴和范围轴）。
您应该使用图表面板在GUI中显示图表。
ChartFactory类包含用于创建“现成”图表的静态方法。

ChartFactory.createLineChart( chartTitle, // chart title
  BaseMessages.getString( PKG, "StepPerformanceSnapShotDialog.TimeInSeconds.Label", Integer
  true, // tooltips
  false ); // urls       
chart.setBackgroundPaint( Color.white );
CategoryPlot plot = (CategoryPlot) chart.getPlot();
plot.setBackgroundPaint( Color.white );
plot.setForegroundAlpha( 0.5f );
plot.setRangeGridlinesVisible( true );
NumberAxis rangeAxis = (NumberAxis) plot.getRangeAxis();
rangeAxis.setStandardTickUnits( NumberAxis.createIntegerTickUnits() );
CategoryAxis domainAxis = plot.getDomainAxis();
domainAxis.setTickLabelsVisible( false );
renderer.setSeriesShape( 0, new Ellipse2D.Double( -3.0, -3.0, 6.0, 6.0 ) );
BufferedImage bufferedImage = chart.createBufferedImage( bounds.width, bounds.height );
ImageData imageData = ImageUtil.convertToSWT( bufferedImage );
