Hello,

I am a beginner at programming and I am trying to build a class for multiple graphic bars that visualize values. I have written the following code:

Graphbar Graphbar1;

void setup() {
 size(500,500);
 
 PFont font;
 font=loadFont("Tahoma-12.vlw");
 textFont(font);
 Graphbar1= new Graphbar(60,60,"Stroom:","A",180,200);
}

void draw() {
 background(150);
 Graphbar1.DisplayPhysScale();
 Graphbar1.DisplayBar();
 Graphbar1.DisplayUnit();
}
class Graphbar{
 int Xpos;
 int Ypos;
 String PhysScale;
 String Unit;
 int Value;
 int Range;
   
 Graphbar(int tempXpos, int tempYpos,String tempPhysScale, String tempUnit, int tempValue, int tempRange ){
   Xpos=tempXpos;
   Ypos=tempYpos;
   PhysScale=tempPhysScale;
   Unit=tempUnit;
   Value=tempValue;
   Range=tempRange;
 
 }
 void DisplayPhysScale(){
   fill(97,118,219);
   stroke(97,118,150);
   rect(Xpos,Ypos,50,20);
   fill(0,18,106);
   text("Stroom:",Xpos+2,Ypos+15);
 }
 
 void DisplayBar(){
   fill(97,118,219);
   stroke(97,118,150);
   rect(Xpos+52,Ypos,210,20);
   fill(188,193,219);
   stroke(0);
   rect(Xpos+57,Ypos+5,200,10);
   fill(0,18,106);
   stroke(0,18,156);
   int x=Value/Range*200;
   rect(Xpos+58,Ypos+6,x,8);
 }
 
 void DisplayUnit(){
   fill(97,118,219);
   stroke(97,118,150);
   rect(Xpos+264,Ypos,40,20);
   fill(0,18,106);
   text(Value,Xpos+267,Ypos+15);
   text(Unit,Xpos+290,Ypos+15);
 }
}

Variable x is declared as a integer and needs to calculate the following:
          Value
int x= --------- x 200
          Range

The problem is that the outcome is always 0 while in my opinion int Value =180 and int Range=200, am I wrong?

Thanks,

Willem
