Echart实现国际化

初始化echart时，前台会获取当前系统所用语言i18nLanguage，根据i18nLanguage设置echart的当前语言

<div class="widget-body">
		<div id="echarts-line-chart" class="chart chart-full"></div>
</div>

i18nLanguage = xxxxx;
function echartinit(){
		var lineChart = echarts.init(document.getElementById("echarts-line-chart"),null, {locale: i18nLanguage});
		
			lineChart.setOption({
				//backgroundColor: '#344b58',
				title: {
				x: '20',
				top: '20',
				textStyle: {
					color: '#fff',
					fontSize: '22'
				},
