Chart Auto Adjustment

I have a chart (chart.js) on my sharepoint site (SP- 2013 Online), that is presenting data dynamically. Sometimes its a lot of data to show, then my Chart dont resize, i want the height to resize, depending on my data.

Heres my script so far, to make the height auto adjust, does anyone has a better solution?

    for(var m = 0; m < data.length; m++){
      height = height * 2;  
      if(data.length > 10){

        height = height - 1;
      }
    }
 function setChartDimensions() {
   var width = 450;
  // height = $(".bottomContent").offset().top - $("canvas").offset().top - 20; 
   if (currentChart) {
       currentChart.chart.aspectRatio = width / height;
   }
  else {
     $("canvas").attr("width", width);
     $("canvas").attr("height", height);
  }
}
