Failed to execute 'arc' on 'CanvasRenderingContext2D': The radius provided (-12) is negative." /visual/js/echarts-liquidfill.js (11676)echarts 球配置项内容和展示

Failed to execute 'arc' on 'CanvasRenderingContext2D': The radius provided (-12) is negative." /visual/js/echarts-liquidfill.js (11676) 按照示例引入的最简单的demo，但一直报这个错，我是引入了echarts.min.js、echarts-liquidfill.js，html定义了<div id="liquidfill-chart" style="width=100px; height = 100px"></div>

      		var chart = echarts.init(document.getElementById('liquidfill-chart'));
		var option = {
			series: [{
				type: 'liquidFill',
				data: [0.6, 0.5, 0.4, 0.3],
				radius:'50%'
			}]
		};
		chart.setOption(option);
