问题：
1. 在echarts跟bootstrap选项卡整合的时候，默认第一个选中选项卡可以正常加载echarts图表，但是切换其他选项的时候不能渲染出其他选项卡echarts图表。
2. echarts自适应怎么实现？
解决办法：
//解决tab切换不显示问题 在加载窗口后重新渲染。
$('a[data-toggle="pill"]').on('shown.bs.tab', function(e) {
for(var i = 0; i < charts.length; i++) {
charts[i].resize();
}
}); //data-toggle="pill还是data-toggle="tab" 根据前面所用标签页的不同来选择
//echarts自适应
var charts = [];
var chart1 = echarts.init(document.getElementById("left1"));
var chart2 = echarts.init(document.getElementById("left2"));
var chart3 = echarts.init(document.getElementById("right11"));
var chart4 = echarts.init(document.getElementById("right12"));
var chart5 = echarts.init(document.getElementById("right21"));
var chart6 = echarts.init(document.getElementById("right22"));
chart1.setOption(option1);
chart2.setOption(option1);
chart3.setOption(option2);
chart4.setOption(option2);
chart5.setOption(option1);
chart6.setOption(option1);
charts.push(chart1);
charts.push(chart2);
charts.push(chart3);
charts.push(chart4);
charts.push(chart5);
charts.push(chart6);
$(window).resize(function() {
for(var i = 0; i < charts.length; i++) {
charts[i].resize();
}
})
下面看一个实现的demo:
demo 完成内容：
1. bootstrap实现响应式布局
2. echats实现自适应
3. 标签页切换、缩放正常显示
