How to create a bar-chart where the "table.sort" change on request with a button!

nachoman

This is my first processing question for my first processing project, so sorry everybody for my ignorance of the software and of the forum rules, I'll be deeply thankful if anyone will be so kind to answer!

My problem is the following one: I would like to do a bar chart representing my 100 favorite songs (according to iTunes reproductions!), where you can change the table.sort, the disposition of the song in genre, artist, n° of reproduction, etc... with some buttons to do it. I've tried to do something with cp5 button, but the main problem is that if i maintain noLoop() the graph don't change, but if I take it away the graph goes crazy. I report down here the code and the CSV table!

Help me please, free hugs and the give of my final project if you do!

CODE:

import controlP5.*;

ControlP5 cp5;

Table table;
int c;
PFont font;
boolean Bottone = false;


void setup() {
  //size(800, 600);
  fullScreen();
  background(255);
  smooth();
  table = loadTable("My Music Numbers_first 100.csv", "header");
  font = createFont("Chivo-Regular-13.vlw", 13);//aggiunta la font

    cp5= new ControlP5(this); 

  cp5.addToggle("Bottone")
     .setPosition(20,180)
     .setSize(90,15)
     ;

}


void draw() {
  //questa linea e la successiva per invertire l'asse delle y
  /*scale(1, -1);
  translate(0, -height);*/

    font = createFont("CircularStd-Bold", 40);
    textFont(font);
    textSize(32);
    fill(#B0F566);
    textAlign(CENTER);
    text("My Favourite Tracks",(width/2),100);
    textSize(18);
    fill(#83B45B);
    text("A data—visualization of the 100 songs that I love most",(width/2),150);


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

    // Access each row of the table one at a time, in a loop.
    TableRow riga = table.getRow(i);
    int posizione = riga.getInt("posizione");
    String n = riga.getString("artista");
    String titolo = riga.getString("titolo");
    int score = riga.getInt("riproduzioni");
    int durata = riga.getInt("durata");
    String album = riga.getString("album");
    int anno = riga.getInt("anno");
    String genere = riga.getString("genere");
    String nazione = riga.getString("nazione");
    int x = 200+(i*10);
    int y = height/2;

    table.sort("riproduzioni");

     if (genere.equals("Alternativa/Indie") == true) {
      c = #B0F566;
    } 
    if (genere.equals("Reggae") == true) {
      c = #4AF2A1;
    } 
    if (genere.equals("Pop") == true) {
      c = #5CC9F5;
    } 
    if (genere.equals("Rock") == true) {
      c = #6638F0;
    }

    if (genere.equals("Hip Hop") == true) {
      c = #E8235E;
    }
    if (genere.equals("Rap") == true) {
      c = #FF1A1A;
    }
    if (genere.equals("Ska") == true) {
      c = #1EF7D1;
    }
    if (genere.equals("Dance Elettronica") == true) {
      c = #FFF41A;
    }
    if (genere.equals("Neofolk") == true) {
      c = #10FF00;
    } 
    if (genere.equals("Soul") == true) {
      c = #2420C4;
    }
    if (genere.equals("Punk") == true) {
      c = #CB7777;
    }

    if (Bottone == true) {
    table.sort("genere");

  } else {
    table.sort("riproduzioni");
  }

    fill(c);
    rectMode(CENTER);
    noStroke();
    rect(x, y, 10, score*4,7);
    //noLoop();

    println(titolo + " " + score);
  }
}
