java绘制一个成交量的统计图

在前方,我用多线程写了一个绘制了股票k线图的步调.这边我再经过绘制一个拍板量的统计图证明对鼠票事变的运用.这边咱们要传入几个参数:<applet code="sellhis.class" archive="sellhis.jar" width="640" height="400"><param name="itemmonth" value="200201"><param name="itemcode" value="00002,00014,00019,00023,00041,00102,00113,00114,00129,00132,00142,00146,00179,00203,00213,00223,00341"><param name="itemval" value="272950,193950,1015600,142700,1618500,671650,2453300,630150,28375,1827660,7700,75700,27375,3375600,47500,17500,17500"><param name="itempce" value="219,156,817,114,2302,540,1974,507,22,1471,6,60,22,4717,38,114,14"></applet>察看演练sellhis.java源步调如次:import java.awt.*;import java.applet.*;import java.awt.font.*;import java.awt.event.*;import java.io.*;import java.lang.*;import java.util.*;public class sellhis extends applet{  static int len;  int leftmargine=50;  int rightmargine=20;  int topmargine=80;  int buttommargine=20;  int width,height,w,h;  int minsticklength=3;  //坐目标短刻度  int majsticklength=8;   //坐目标长刻度  int minstick=10;  int majstick;  string title;  string xtitle="股票代碼";  string xcode[];  float ydata[],xpce[];  string maxpce;  boolean mouse_move;  int x0,y0,x,y,hx,hy;  label label[]=new label[3];  boolean mouse_move=false;  public void init() {    width=this.getbounds().width;    height=this.getbounds().height;    w=width-leftmargine-rightmargine;    h=height-topmargine-buttommargine;    setsize(width,height);    color bc=new color(229,229,229);    setbackground(bc);    setlayout(null);    for(int i=0;i<3;i++){      label[i]=new label();      label[i].setforeground(color.blue);      this.add(label[i]);      if(i==0)        label[i].reshape(75,topmargine-25,60,15);      if(i==1)        label[i].reshape(230,topmargine-25,80,15);      if(i==2)        label[i].reshape(505,topmargine-25,60,15);    }    try{      title=gettitle(getparameter("itemmonth"));    }    catch(exception e){      system.out.println("param itemmonth error!");   system.out.println(e);
