JFreeChart.getPlot介绍

[英]Returns the plot for the chart. The plot is a class responsible for coordinating the visual representation of the data, including the axes (if any).
[中]返回图表的绘图。plot是一个类，负责协调数据的视觉表示，包括轴（如果有）。

  String h = req.getParameter("height");
  if(h==null)     h=String.valueOf(defaultH);
  Color graphBg = stringToColor(req.getParameter("graphBg"));
  Color plotBg = stringToColor(req.getParameter("plotBg"));
  if (graph==null)    graph = createGraph();
  graph.setBackgroundPaint(graphBg);
  Plot p = graph.getPlot();
  p.setBackgroundPaint(plotBg);
  return graph.createBufferedImage(Integer.parseInt(w),Integer.parseInt(h),info);
