javascript - Dual Axes with column drill down, Cannot column click -

i have dual axes highchart, wit column drill down , spline, there problem column area below level of spline, nt goes in drill down of column.

	$(function() {  	  highcharts.setoptions({  	    lang: {  	      drilluptext: '<< go {series.name}'  	    }  	  });    	  highcharts  	    .data({  	      csv: document.getelementbyid('tsv').innerhtml,  	      itemdelimiter: '\t',  	      parsed: function(columns) {    	        var brands = {},  	          cpc = {},  	          brandsdata = [],  	          cpcdata = [],  	          temp = {},  	          versions = {},  	          drilldownseries = [],  	          $container = $('#container'),  	          chart = $('container').highcharts(),  	          origchartwidth = 1500,  	          origchartheight = 600,  	          chartwidth = origchartwidth,  	          chartheight = origchartheight;
