一、X轴显示所有的刻度
xAxis: {
//类目轴中 boundaryGap 可以配置为 true 和 false。默认为 true，这时候刻度只是作为分隔线，标签和数据点都会在两个刻度之间的带(band)中间。
boundaryGap:false,
//坐标轴刻度标签的相关设置。
axisLabel :{
//坐标轴刻度标签的显示间隔，在类目轴中有效。可以设置成 0 强制显示所有标签。
interval:0
},
data:responseData.data.date
},
二、图表显示所有的节点
//true 显示所有的节点，但是允许拖动，鼠标显示拖拽样式 //false 显示部分节点，但是不允许拖动，鼠标显示可点击 calculable : true,
三、节点的样式设置
series: [{
//节点的样式,triangle为三角形，circle为原点，默认值
symbol:"circle",
name: '销量',
type: 'line',
data: responseData.data.count
}]
四、节点绑定事件
// 使用刚指定的配置项和数据显示图表。
myChart.setOption(option);
//给节点添加click事件
/*
* 事件处理函数。格式为:(event: Object)
* 可选。回调函数内部的context，即this的指向。
* */
myChart.on('click', function (handler,context){
console.dir(handler);
console.dir(context);
//获取节点点击的数组序号
var arrayIndex = handler.dataIndex;
//获取数据
var urlParam = responseData.data.date[arrayIndex];
});
