VUE 使用echarts线图,常用属性介绍

文章就是介绍应该会用得上的属性设置。这里不是安装教学哈,安装教学出门左转!
介绍全在代码的备注中,请慢慢食用!

methods: {
   
	myEcharts() {
   
	  var that = this
      // 基于准备好的dom,初始化echarts实例
      var myChart = this.$echarts.init(document.getElementById("main"));
      // 指定图表的配置项和数据
      var option = {
   
	  	legend: {
   
          //这个控制的是顶部的标签,大小、颜色、样式之类的、还有是否选中状态
          show: true,//是否显示
          selected: {
   
            // 选中状态,值要与series里的name相同
            PSA: true,
            尿垫: false
          },
          inactiveColor: "#ccc", //未选择中颜色
          icon: "circle", //头顶标识形状
          selectedMode: "single",//只能同时选中一个查看
        },
        tooltip: {
   
          //图例组件。鼠标悬停浮窗,显示数值

A year and a half year ago, I published this article to the Codeguru site and got a number of requests about the Kriging algorithm contour map. Unfortunately, my project was changed shortly after that article and later I quit the company so I couldn‘t find time to finish this Contour business. A week ago, I happened to need a contour map again so I decided to solve the Kriging algorithm. I searched the Internet for a commercial library but they all look ugly and hard to use. So, I made up my mind to make my own algorithm. The Kriging algorithm is easy to find, but this algorithm needs a Matrix and solver (LU-Decomposition). Again, I couldn‘t find suitable code for this. I tried to use GSL first but this made my code too big and was slower. Finally, I went back to "Numerical Recipe in C"—yes, that horrible-looking C code—and changed the code there to my taste.If you read this article before, the rendering part hasn‘t been changed much. I added the Kriging algorithm and revised the codes a little bit. Following is the Kriging Algorithm:templatedouble GetDistance(const ForwardIterator start, int i, int j){ return ::sqrt(::pow(((*(start+i)).x - (*(start+j)).x), 2) + ::pow(((*(start+i)).y - (*(start+j)).y), 2));}templatedouble GetDistance(double xpos, double ypos, const ForwardIterator start, int i){ return ::sqrt(::pow(((*(start+i)).x - xpos), 2) + ::pow(((*(start+i)).y - ypos), 2));}templateclass TKriging : public TInterpolater{public: TKriging(const ForwardIterator first, const ForwardIterator last, double dSemivariance) : m_dSemivariance(dSemivariance) { m_nSize = 0; ForwardIterator start = first; while(start != last) { ++m_nSize; ++start; } m_matA.SetDimension(m_nSize, m_nSize); for(int j=0; j<m_nSize; j++) { for(int i=0; i<m_nSize; i++) { if(i == m_nSize-1 || j == m_nSize-1) { m_matA(i, j) = 1; if(i == m_nSize-1 && j == m_nSize-1) m_matA(i, j) = 0; continue; } m
