Highcharts

问题 When putting multiple charts tooltips from upper charts are hidden behind others. I found some tips on how to it but nothing helped. Is there anyway to keep tooltips on top of charts? The example is here: http://jsfiddle.net/Zw3uM/ Thanks a lot! 回答1: This is pure html : Any div element loaded after ( meaning appearing after on the html page) will always be in front. In order to get the first chart tooltip be in front of the second : load the second in first and set its y position on the page

问题 I want to display tooltip in Synchronized charts. Please see this Jsfiddle $('#container').bind('mousemove touchmove touchstart', function(e) { var chart, point, i, event; for (i = 0; i < Highcharts.charts.length; i = i + 1) { chart = Highcharts.charts[i]; event = chart.pointer.normalize(e.originalEvent); // Find coordinates within the chart point = chart.series[0].searchPoint(event, true); // Get the hovered point if (point) { point.onMouseOver(); // Show the hover marker chart.tooltip

问题 I've been able to get Highstock to work in a sample html file, but in the application I'm working on, the same Highstock code loads part ways and then throws an error: "elem.ownerDocument is undefined" around line 5950 of the unminified code of jQuery 1.5.1 (the getComputedStyle function). After some console logs, I discovered that the elem that throws the error is in fact a Highstock object and not a DOM element. I also discovered that the jQuery function in question doesn't even get called

问题 I am using the column charts for my project. I have written a custom function that colors each bar of the chart based upon its y value. This works fine when I initialize the chart. As I hover over the chart, the color of the bar goes back to the default and my custom colors never return. I have tries disabling on hover but that doesn't seem to work. I don't want the color to change even when hovered over the bar. Any suggestions? 回答1: You are updating color in a wrong way, use point.update()

问题 i am building a dashboard with gridster and highcharts. If i resize the window and a widget with a highchart is bigger than the window, i want to resize it to make it smaller and gridster should recalculate the positions of the others.

问题 I'm using Angular 7 along with HighCharts. I'm passing a function to my high charts click event, but I also need to access some variable from the component. Here is the code for my event: events: { click: function (e: any) { console.log(this.xAxis[0].min) console.log(this.componentVariable) } } I can access the value of xAxis but not the variable componentVariable because it doesn't exist in the context. I cannot bind this to the function either, because then I won't have access to xAxis .
