I need to develop above mentioned bubble chart which is developed in google chart to High chart [bubble] .

解决方案

Based on the answer from this topic - stepped-color-shading-in-highcharts-doughnut-chart.

Wrapping bubble's prototype:

var bubbleProto = Highcharts.seriesTypes.bubble.prototype;

  bubbleProto.axisTypes = ['xAxis', 'yAxis', 'colorAxis'];
  bubbleProto.optionalAxis = 'colorAxis';
  bubbleProto.colorKey = 'y';

  Highcharts.wrap(bubbleProto, 'translate', function(proceed) {
    proceed.apply(this, Array.prototype.slice.call(arguments, 1));

    Highcharts.seriesTypes.heatmap.prototype.translateColors.call(this);
  });
