我试图用js和php实现图形。
我创建了图表。现在，当用户单击图形点时，它会显示y轴值和x轴值。我想在用户点击图表点时显示另一个值（x和y除外）。我已经从ajax文件返回了所有这些x，y和z值。但是无法实现z索引。 Plz帮助我。
$("document").ready(function(event){
var pickerOpts = {
dateFormat:"d/m/yy"
};
$('.date').datepicker(pickerOpts);
function loadGraph(d1,d2){
$.ajax({
dataType:'json',
type:'POST',
url:'../ajaxtaskAnalytics',
data:{
date1:d1,
date2:d2
},
success:function(result){
$.parseJSON(result);
var gval=[];
for(var i=0;i<result['tasks'].length;i++){
gval.push([
Date.parse(result['tasks'][i].dt+' UTC')
,
result['tasks'][i].number,
result['tasks'][i].usercount
]);
}
var options = {

您需要在图表的工具提示选项中使用formatter属性，并且您需要一个包含z值的数组。请参阅以下示例：
