Processing Class/object variable stacking - class

Question

So I have a problem that I've managed to fix before (by fluke) in simpler programs, but still don't know what the actual problem is.
I have created an class containing the following variables g1.display(tableHr, hrMeasure, 37, 10, 20,160, 0);. The problem is, when I run one object of the class it's all fine and a nice graph is created. Though when I run two objects of the class, the first graph in the program runs fine and the second one gets morphed out of proportion. Almost like variables are stacking or multiplying each other.
Anyone familiar with this problem?
The Main sketch's code:
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]);
}

Ensure you are using independent instances, for example:
Graph g1 = new Graph();
Graph g2 = new Graph();
then in draw():
g1.display(tableHr, hrMeasure, 40, 15, 25,200,100);
g2.display(tableSpo, spoMeasure, 37, 1, 3,160,2);
Full listing:
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");
