本文整理了Java中org.jfree.chart.plot.Plot.draw()方法的一些代码示例,展示了Plot.draw()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。Plot.draw()方法的具体详情如下:
包路径:org.jfree.chart.plot.Plot
类名称:Plot
方法名:draw

Plot.draw介绍

[英]Draws the plot within the specified area. The anchor is a point on the chart that is specified externally (for instance, it may be the last point of the last mouse click performed by the user) - plots can use or ignore this value as they see fit.

Subclasses need to provide an implementation of this method, obviously.
[中]在指定区域内绘制绘图。定位点是图表上外部指定的一个点(例如,它可能是用户最后一次单击鼠标的最后一个点)——绘图可以根据需要使用或忽略该值。
显然,子类需要提供这种方法的实现。

/**
 * The resulting IVisualization shows a chart which consists a TimeSeries for each FeatureOfInterest
 * contained in the observationCollection.

  // draw plot into image:
  BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);

/**

 * 
 * Auf X- und Y-Achse wird jeweils eine observedProperty abgetragen.
 * 
 * Ein Punkt steht dann f�r ein Wertepaar (X,Y) f�r ein FOI zu einem bestimmten Zeitpunkt.
 * 
 * TODO PROBLEM: Macht nur Sinn, wenn f�r jedes (FOI, Time)-Tuple jeweils ein Wert f�r BEIDE
 * observedPropertys enthalten ist !!!!
