Hello everybody! I have a new question to ask. I want to insert  a draw into a GPanel. My draw code s that:

 

pnl = new GPanel(this, "Panel", -650,0,300,72); 

void renderWave1() {
  noStroke();

for (int x = 0; x < linesFase.length; x++) {
    fill(255,0,0);
    rect(x*xspacionTota,(height-20)-recordsFase[x].consumo/2,0.2,recordsFase[x].consumo/2);
 
  }

}

If anybody could help me, I'll be pleased. Thanksin advance
