How do i make 2 checkbox filters in my processing datavisualisation (with csv data file)

tomvandijk

Hello all, I want to have 2 checkbox filters in my processing datavisualization. The checkboxes must filter the numbers (nr) from 1-7 (1checkbox) and numbers 8-13 (1 checkbox). The problem is: I have no clue how to do this. Is there anyone who can help me with this?

 Table table;
   String[] land={};
   float[] bbp = {};
   int[] nr = {};
   float r = random(250);



void setup (){
    table = loadTable("data.csv", "header");
    for (TableRow row : table.rows()) {
       land = append(land, row.getString("land"));
       bbp = append(bbp, row.getFloat("bbp"));
       nr = append(nr, row.getInt("nr"));
       println(land.length);
 }
  size(2000,600);
  background(240);
  smooth();
  stroke(50,50,50,50);
  strokeWeight(2);
 }

  void draw (){
  background(240);
  line(0, height/2, width, height/2);
  for(int i=0; i< nr.length;i++){
           float c = nr[i]*12;
  fill(250, c,c,200);
  ellipse(nr[i]*110 -20 , height/2, bbp[i]*3, bbp[i]*3);
  fill(30);

pushMatrix();
translate(nr[i]*110 -20, height/2 - bbp[i]/2);
rotate(radians(-45));
text(land[i],-50 ,50);
text(bbp[i],10,10);
textSize(18);
popMatrix();

text("BBP per land plaats 1t/m13",10 ,height/3);
text("Bron: https://nl.wikipedia.org/wiki/Lijst_van_landen_naar_bbp_per_hoofd_van_de_bevolking", height/2, width/4);
smooth();
}
    }
