我已经在我的angular 4应用程序的高图工具提示上显示了x和y值。请参阅工具提示的格式化程序功能。 graphdata数组使用三个值初始化，如下所示 如果您在脊柱图表代码中，我正在将系列对象传递给静态图表方法。现在，我可以访问系列对象。系列对象包含数组 数据对象。每个元素包含例如{90000，1，1000000}。如何根据前两个值找到第三个值。我想我需要 查找point.x == firstelement和point.y ==第二个元素，然后显示第三个元素。 所以在语法上我在考虑series.find（），但不确定如何构造
我试图在格式器功能的表构造中用标签Captive Required填充第三行。标题样条图组件下方的完整代码可用
const table = function(format, point) {
let txt = '<strong style="font-size:12px;color:' + point.series.color + '">' + point.series.name + '</strong><br><br>';
txt += '<table>';
txt += row('GRAPH_XAXIS', format(point.x));
txt += row('GRAPH_YAXIS', format(numberPercentPipe.transform(point.y)) + '%');
txt += row('Captive Required', + '%');
txt += '</table>';
return txt;
};
这是图表系列初始化的方式
this.chartSeries = value.map(element => ({ data: element.graphData, name: element.strategyName, color: element.strategyColor }));
图形数据
trigger2Output.StressTestAnalysis.GraphData = new decimal[][]
{
new decimal[] { 90000, 1, 1000000},
new decimal[] { 91000, 1, 2000000},
new decimal[] { 92000, 1, 3000000},
new decimal[] { 93000, 1, 4000000},
new decimal[] { 94000, 1, 5000000},
new decimal[] { 95000, 1, 6000000},
new decimal[] { 96000, 1, 7000000},
new decimal[] { 121, 3434,1000000},
new decimal[] { 121, 3434,1000000},
new decimal[] { 121, 3434,1000000},
new decimal[] { 121, 3434,1000000},
new decimal[] { 121, 3434,1000000},

new decimal[] { 121, 3434, 1000000}
} ;

答案 0 :(得分：1)
我通过以下代码修复了
let xyz= series
.find(s => s.name == point.series.name).data
.find(x => x[0] === point.x && x[1] === point.y);
