set height of chart based on number of categories

Ok - this works now, allowing for a minimum height of 400:

var params = arguments[0], $ = skuid.$;<br>var repCount;<br>repCount = params.xAxis[0].categories.length;<br>dynHeight = Math.max(repCount*20,400);<br>$('#taskChart').height(dynHeight);<br>$('.sk-chart-wrapper').css('height',dynHeight);
