1、主要得展示-折线图,x轴可以滑动,如图详细代码如下:

{

tooltip: { //提示框取值默认值,即鼠标移动到柱状图会显示内容
trigger: "axis", //触发类型;轴触发,axis则鼠标hover到折线图显示全部数据,item则鼠标hover到折线点显示相应数据
position: function (point, params, dom, rect, size) { //设置提示框位置随鼠标移动,并解决提示框显示不全的问题
var x = 0; //x坐标位置
var y = 0; //y坐标位置
var pointX = point[0]; //当前鼠标位置
var pointY = point[1];
var boxWidth = size.contentSize[0]; //提示框大小
var boxHeight = size.contentSize[1];
if (boxWidth > pointX) { //boxWdith > pointx 说明鼠标左边放不下提示框
x = 5;
} else { //左边放得下
x = pointX - boxWidth;
}
//boxHeight > pointY 说明鼠标上边放不下提示框
if (boxHeight > pointY) {
y = 5;
} else { //上边放得下
y = pointY - boxHeight;
}
return [x, y]
},
axisPointer: {

return curYear + '.' + params[0].name + '<br/>' + "客流:" + params[0].value
}
},
// 缩放平移组件
dataZoom: [
{
type: 'inside', //slider有滑块,inside内置
disabled: false, //是否停止组件功能
xAxisIndex: 0, //x轴,可以用数组表示多个轴
zoomLock: true, //是否锁定区域大小(true,只能平移不能缩放)
preventDefaultMouseMove: false,
filterMode: "empty",
startValue: startValue, //一行有几个(起始数组下标)
endValue: endValue, //一行有几个(结束数组下标)
start: null,
end: null,
},
]
}
}
特别要注意得是,在引用得一些echarts组件时要进行配置,若不配置,可能引发一些数据得不能试用
在echarts配置中,引入,例子,在相应得echarts.js中
import Vue from "vue";
//映入echarts
import ECharts from "vue-echarts/components/ECharts";
import "echarts/lib/chart/bar";
import "echarts/lib/chart/line";
import "echarts/lib/chart/pie";
import "echarts/lib/chart/gauge";
import 'echarts/lib/chart/radar';
import "echarts/lib/component/tooltip";
import "echarts/lib/component/title";
import "echarts/lib/component/legend";
import "echarts/lib/component/dataZoom";
import "echarts/lib/component/toolbox";
import "echarts/lib/component/visualMap";
import 'echarts/lib/component/markLine';
Vue.component("v-charts", ECharts);
