处理Class/object变量堆叠

Question

所以我有一个问题，我以前在更简单的程序中设法（侥幸地）解决了这个问题，但仍然不知道实际问题是什么。

我创建了一个包含以下变量的 class g1.display(tableHr, hrMeasure, 37, 10, 20,160, 0);。问题是，当我运行 class 的一个对象时，一切都很好，并且创建了一个漂亮的图形。虽然当我运行 class 的两个对象时，程序中的第一个图形运行很好，而第二个变得不成比例。几乎就像变量在相互堆叠或相乘。

有人熟悉这个问题吗？

主草图的代码：

Graph g1 = new Graph();
Button b1 = new Button();

TableRow hrMeasure;
TableRow spoMeasure;
TableRow tempMeasure;

Table tableHr;
Table tableSpo;
Table tableAbp;
Table tableResp;
Table tableTemp;

int i;
int border;
float p;

PFont font;
PFont font2;
String alarmColor;


void setup(){
  font = loadFont("data/OpenSans-36.vlw");
  textFont(font,36);

  frameRate(15);
  smooth(8);
  size(1024,768);

  tableHr = loadTable("testfile.csv", "header");
  tableSpo = loadTable("testfile2.csv", "header");
  tableAbp = loadTable("testfile3.csv", "header");
  tableResp = loadTable("testfile4.csv", "header");
  tableTemp = loadTable("testfile5.csv", "header");

}

void draw(){

  retrieveData();
  GUI();
  relativeGraph();
  buttons();

    g1.display(tableHr, hrMeasure, 40, 15, 25,200,100);
 // g1.display(tableSpo, spoMeasure, 37, 1, 3,160,2);
 // g1.display(tableTemp, tempMeasure, 37, 1, 3,160,3);
 // g1.display(tableHr, hrMeasure, 37, 13, 18,160,4);
 // g1.display(tableHr, hrMeasure, 37, 13, 18,160,5);
}

//retrieving data from the csv file
void retrieveData(){
  i++;
  hrMeasure = tableHr.getRow(i);
  spoMeasure = tableSpo.getRow(i);
  tempMeasure = tableTemp.getRow(i);  
}

Class:

class Graph {
int adjustment;
float p;
int greenRelative, yellowRelative, redRelative;
float[] measure = new float[1500000];
String alarmColor;
int timer, counter;
int greenTimer, yellowTimer, redTimer;
int graphHeight = 80;
int graphLength = 800;

void display(Table table, TableRow measurement, int average, int bound1, int bound2,int x, int y){

p = measurement.getFloat("value");

pushMatrix();
translate(width,0);
scale(-1,1);

for (int i = 0; i < table.getRowCount(); i++){

  adjustment = width-table.getRowCount()-x; // adjustment to the x-coordinate, so every graph will start at 0

//if statement for green readings
   if(measure[i]  > average-bound1 && measure[i] < average+bound1){    
   stroke(0, 255, 0);
   strokeWeight(1);  
   alarmColor = "green";
 }else{

//if statement for yellow readings
   if(measure[i]  <= average-bound1 && measure[i] > average-bound2|| measure[i]  >= average+bound1 && measure[i] < average+bound2){
   stroke(255, 255, 0);
   strokeWeight(1);

   alarmColor = "yellow";

//else red
 }else{stroke(255, 0, 0);
   strokeWeight(1);

   alarmColor = "red";
 }}
line(i+adjustment, graphHeight-map(measure[i], average-bound1-bound2, 37, 0,graphHeight/2)+y, (i+1)+adjustment, graphHeight-map(measure[i+1], average-bound1-bound2, 37, 0,graphHeight/2)+y); 
}
popMatrix();

for(int i=0; i < table.getRowCount(); i++){
measure[i] = measure[i+1];
measure[i+1] = p;
println(measure[i]);
}

确保您使用的是独立实例，例如：

Graph g1 = new Graph();
Graph g2 = new Graph();

然后在 draw():

g1.display(tableHr, hrMeasure, 40, 15, 25,200,100);
g2.display(tableSpo, spoMeasure, 37, 1, 3,160,2);

完整列表：

Graph g1 = new Graph();
Graph g2 = new Graph();
Graph g3 = new Graph();
Graph g4 = new Graph();
Graph g5 = new Graph();
Button b1 = new Button();

TableRow hrMeasure;
TableRow spoMeasure;
TableRow tempMeasure;

Table tableHr;
Table tableSpo;
Table tableAbp;
Table tableResp;
Table tableTemp;

int i;
int border;
float p;

PFont font;
PFont font2;
String alarmColor;


void setup(){
  font = loadFont("data/OpenSans-36.vlw");
  textFont(font,36);

  frameRate(15);
  smooth(8);
  size(1024,768);

  tableHr = loadTable("testfile.csv", "header");
  tableSpo = loadTable("testfile2.csv", "header");
  tableAbp = loadTable("testfile3.csv", "header");
  tableResp = loadTable("testfile4.csv", "header");
  tableTemp = loadTable("testfile5.csv", "header");

}
