Help for writing an app (running zones using Karvonnen method)

The whole code doesn't fit in the post because of the pics. I'm going to attach the whole code to this post (I modified to .odt, so that there's no security issue with posting it). Still, the end of the code (after the pictures) is here:

g.setFont("Vector",20);
//Subdivided zones for better readability of zones when calling the background images. //Changing HR zones will trigger the change of the background image and the HR to change zone.

if (hr <= minhr) {
  console.log("HR too low");
} else if (hr <= hrr*0.6 + minhr) {
  g.drawImage(getzone1(),0,0,{scale:1.2});­g.drawString("Z1", 32,78);g.drawString(minzone2, 62,20);
} else if (hr <= hrr*0.64 + minhr) {
  g.drawImage(getzone2a(),0,0,{scale:1.2})­;g.drawString("Z2", 32,78);g.drawString(maxzone2, 62,20);g.drawString(minzone2, 62,136);
} else if (hr <= hrr*0.67+minhr) {
  g.drawImage(getzone2b(),0,0,{scale:1.2})­;g.drawString("Z2", 32,78);g.drawString(maxzone2, 62,20);g.drawString(minzone2, 62,136);
} else if (hr <= hrr * 0.7 + minhr) {
 g.drawImage(getzone2c(),0,0,{scale:1.2})­;g.drawString("Z2", 32,78);g.drawString(maxzone2, 62,20);g.drawString(minzone2, 62,136);
} else if (hr <= hrr * 0.74 + minhr) {
  g.drawImage(getzone3a(),0,0,{scale:1.2})­;g.drawString("Z3", 32,78);g.drawString(maxzone3, 62,20);g.drawString(maxzone2, 62,136);
} else if (hr <= hrr * 0.77 + minhr) {
  g.drawImage(getzone3b(),0,0,{scale:1.2})­;g.drawString("Z3", 32,78);g.drawString(maxzone3, 62,20);g.drawString(maxzone2, 62,136);
} else if (hr <= hrr * 0.8 + minhr) {
  g.drawImage(getzone3c(),0,0,{scale:1.2})­;g.drawString("Z3", 32,78);g.drawString(maxzone3, 62,20);g.drawString(maxzone2, 62,136);
} else if (hr <= hrr * 0.84 + minhr) {
  g.drawImage(getzone4a(),0,0,{scale:1.2})­;g.drawString("Z4", 32,78);g.drawString(maxzone4, 62,20);g.drawString(maxzone3, 62,136);
} else if (hr <= hrr * 0.87 + minhr) {
  g.drawImage(getzone4b(),0,0,{scale:1.2})­;g.drawString("Z4", 32,78);g.drawString(maxzone4, 62,20);g.drawString(maxzone3, 62,136);
} else if (hr <= hrr * 0.9 + minhr) {
  g.drawImage(getzone4c(),0,0,{scale:1.2})­;g.drawString("Z4", 32,78);g.drawString(maxzone4, 62,20);g.drawString(maxzone3, 62,136);
} else if (hr <= hrr * 0.94 + minhr) {
  g.drawImage(getzone5a(),0,0,{scale:1.2})­;g.drawString("Z5", 32,78);g.drawString(maxzone5, 62,20);g.drawString(maxzone4, 62,136);

} else if (hr >= maxhr - 2) {
  g.clear();g.drawImage(getzonealert(),0,0­,{scale:1.2});g.setFont("Vector",38);g.d­rawString("ALERT", 20,53);g.drawString("HR limit", 18,84);
