Hi there,
i would like to draw so many lines which quantity is given in an array.
In this example there should be only 3 lines, but processing is drawing more than 3 lines. I don't know why.
Perhaps you can help me? Any help would be appreciated.
Thanks a lot!

Hi,
I've got another new problem.
I would like to draw some separated lines, which data are given. I thought of an two dimensional array?! E.g.

int[][] daten = { {200,500,300,100}, // the data for line 1, the first coordinatex for the vertex is given, you can see it in the code beneath
                  {300, 400, 200, 350}, // data for line 2,
                  {600, 250, 300, 200}, // data line 3
                  {800, 300, 150, 50}  // data line 4
                };
As you can see beneath the code, the xCoordinate should be in all lines the same.The lines should be drawn one after the other. And it should be extendable.
At the moment it's only possible to draw one line. Don't know how I can handle it with more data and lines. Do you have an idea?

1. int[] daten =   {200, 300, 300, 100};
   
   
   
   void setup() {
     size(1000, 1000);
     for (int i=0; i<daten.length; i++)
       println (daten[i]);
   }
   
   void draw() {
     beginShape();
     noFill();
     smooth();
     stroke(0, 0, 255);
     int x=100;
     for (int i=0; i< daten.length; i++)
     {
   
   
       vertex(x, daten[i]);
       x= x+200;
       ;
     }
     endShape();
   }
   

And this is how ist should looks like (user 1 is the first line, user 2, the second, ...only these should be drawn at the moment) :



Any help would be appreciated. Thanks!

Hi there,
I would like to draw lines, which quantity is given in an array. But processing is drawing only and always 2 lines and not more.
Here is the code:

1. int[][] daten = { {200,500,300,100},
                     {300, 400, 200, 350},
                     {600, 250, 300, 200},
                     {800, 300, 150, 50}
                   };
   
   int anzahlachsen = daten[0].length; // zeigt an, wieviele Punkte/Achsen es gibt //  how many lines(axis)
   int anzahllinie = daten.length; // zeigt an, wieviele VerbindungsLinien es gib
   int x;
   
   Achse[] achsen = new Achse[anzahlachsen];
   
   void setup () {
     size(1000,1000);
     for (int i = 0; i < achsen.length; i++) {
     achsen[i] = new Achse(100+x,50,100+x,500);
    x = 200;
   }
   }
   void draw() {
     for (int i = 0; i < achsen.length; i++) {
       achsen[i].display();
     }
   }
    
   
2. class Achse {
     color c;
     int x1;
     int y1;
     int x2;
     int y2;
     int einheit;
    
   // Konstruktor
   Achse(int xpos1, int ypos1, int xpos2, int ypos2) {
     c = color (0);
     x1 = xpos1;
     y1 = ypos1;
     x2 = xpos2;
     y2 = ypos2;
     einheit = 20;
   }
    
    void display (){
    //Achse ist nur eine Linie
    stroke(c);
    line (x1, y1, x2, y2);
    zeigeEinheiten ();
    }
    
    void zeigeEinheiten()
    {
      int y=y2;
      while (y >= y1)
      {
      line (x2, y, x2+5, y);
      y= y-einheit;
      }
    }
   }
   

Hi there,

i’m a beginner with the processing language (and any other), that means at the moment i really get lost in space… :/

I should do a class for a parallelcoordinategraph, but I don’t know how to. We got last semester some basics in processing, but not more. It should be a simple graph  and a simple class. That means, the data is given in an array, not in a text file or in a .csv or something like that. For example I have those data: {200, 500, 300, 100}, {300, 400, 200, 350}. The data in the first bracket is user 1 (line1) with 4 coordinates (points), the second bracket is user 2 with 4 coordinates. It should be extendable for more users. It means in this example I will need 2 lines having 4 points (i thought i will do this with the vertex function). On each point there should be an axis. The first axis has the xcoordinate: 200, the second 400, the third 600 and so on, depending on how many numbers are in one bracket. The users (lines), the points and the axis should be extendable.
