Highcharts

问题 I'm having trouble returning a JSON object, instead all I get is an undefined variable. This code is supposed to return a json element from an API. It seems to work in the success: function, but once I try and take that data elsewhere it just displays 'undefined' var datas; datas = getdata(); //getdata(); createChart(datas) alert('2datass'+datas); // this returns undefined function createChart(data){ alert(data); //outputs undefined } function getdataaa(){ alert('ajax'); $.ajax({ type: "GET",

问题 Highcharts and stockcharts, they both provide the options to add some padding at the x axis in order to avoid drawing some values on the edge of the plot area (left or right).

Why is the line not displayed in highcharts? Here is my code: // Mouseover handler function(e) { var that = this; var series = this.series; console.log(series); for (var i = 0; i < series.data

问题 I have a tooltip format like this: tooltip: { formatter: function() { return Highcharts.dateFormat('%A, %b %e, %Y',new Date(this.x)) +'<br/>'+ this.series.name + ': ' + '<b>'+ this.y +'</b>'; } }; How can I add color to my series.name because now they all black. In my chart after drawing, different series.name has different colors. Thanks 回答1: use this: tooltip: { formatter: function() { var toolTipTxt = '<b>'+ this.x +'</b>'; toolTipTxt += '<br/><span style="color:'+ this.point.series.color
