To remove/diminish grid-lines, you can set maxTicksLimit property of ticks to a number (amount of grid-lines - approx.) , like so :

scale: {
   ticks: {
      maxTicksLimit: 3
   }
}

BONUS: If you wish to remove all the grid-lines, setting maxTicksLimit to 0 will not work. Instead add the following in your chart options :

gridLines: {
   display: false
}

To remove grid-line labels (ticks), you can set display property to false for scale ticks , as such :

scale: {
   ticks: {
      display: false
   }
}
