您好我正在尝试实施流行的Wator模拟,但我的鱼群图表无法正常工作。出于某种原因,图表会上下移动一条线,而不是根据需要绘制每条曲线。这是代码:
/**Draws the graphs that will display the populations of Fish and Shark over time*/
public void paintComponent (Graphics g)
{
super.paintComponent(g);
Graphics2D g2 = (Graphics2D) g;
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
/**Graph the fish population */
g2.setColor (Color.GREEN);
ArrayList<Integer> pixelFish = convertToPixels(numFish); //returns fish population as pixel values
ArrayList<Point> points = new ArrayList<Point>();
Point oldPoint = new Point (0, pixelFish.get(0));
points.add(oldPoint);
//adds all points to point arrayList
for (int i = 1; i < pixelFish.size(); i++)
{
oldPoint = new Point (count,pixelFish.get(count));
points.add(oldPoint);
}
//draws lines
for (int j = 1; j < points.size(); j++)
{
g2.drawLine ( (int) points.get(j-1).getX(), (int) points.get(j-1).getY(), (int) points.get(j).getX(), (int) points.get(j).getY());
}
}
