Highcharts

问题 I am using highchairs 3.0 to create a graph that has N Boxes on it. So far so good. However, one of the user desires is to draw a few plotLines (based on values on the Yaxis) for each Box on the graph. The catch is that the information is different for each of the boxes, so they want the plotLine to just extend from the start of the box on the left side (x-axis basis) to the right of the single box. Highchairs by default draws the y-axis plotLines (and plotBands, looked at those too) all the

问题 Is it possible to change the legend symbol color in Highcharts? For example demo example contains two series and the symbols in legend are in blue and black (same as the series).

问题 I am trying to build a GANTT chart as in this JSFiddle example [ http://jsfiddle.net/2xkfm87e/11/ ] (I have now updated this fiddle to the working version using jlbriggs' input below. It also includes some other options I needed -i.e. tooltip on each interval.) However, I need to display all the categories even if one or more do not have any associated data. The end user needs to be aware that there is no data associated with that category. In my JSFiddle example, the best I could come up

问题 Previous help here has got me to the current stage with my Highcharts project, however I am still hitting a major stumbling block. Highcharts chart is not loading data retrieved using .getJSON. I am at a loss as to why the html is not rendering the chart and load the data from data.php. All code below, does anyone have any ideas? @PawełFus php <?php $con = mysql_connect("ip_address","root",""); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("test", $con); $result =

问题 I want to show multiple tool tips at the same time in a Highchart. The basic requirement is like whenever the mouse is hovered over a point in the series I need to show the tool tip for all the points within a radius X of the hovered point. I have tried something like this so far : http://jsfiddle.net/vmso2dbf/ $(function () { $('#container').highcharts({ title: { text: 'Multiple tooltips' }, plotOptions: { series: { point: { events: { mouseOver: function (event) { var r = 50; var arr = [];

问题 As per the below screenshot I have a bar chart on the left which, when I click on, opens the bar chart on the right. What this then does is open up another bar graph, and I want to click on an element on that. The problem is that the className is "Highcharts-series-group", the same as the previous element locator I used. I've attached a screenshot below of the option I am trying to select (it's the graph on the right) Please see below for the HTML, as I don't think it is clear above <div id=

问题 Is there any way of showing a 1:1 diagonal line in Highcharts? I am looking for a line which X and Y values always match. I know how to render a line in Highcharts using the renderer, however, I don't want an independent line but one that reacts to the chart resizing/zooming. A series with [(0,0),(1,1)] is not really an option (it would affect zooming). Something like this except x and y axis might vary their value due to zooming. 回答1: You can do it by detecting the setExtremes() event on you

问题 Using Javascript, I am trying to convert some JSON data into the format used in Highcharts' basic line chart. What I have to start with: originalArray = [ ['valueA', 1], ['valueA', 0], ['valueB', 9], ['valueB', 9], ['valueB', 3], ['valueC', 11] ] And what I'm trying to create using the above: desiredArray = [{ name: 'valueA', data: [1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0] }, { name: 'valueB', data: [0, 0, 0, 1, 0, 0, 0, 0, 0, 2, 0, 0] }, { name: 'valueC', data: [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1

问题 I am using highcharts and I want to change the color of bar depending on their Y axis values. Something like: { color: '#92D050', //DEFAULT COLOR OF CURRENT YEAR BAR ON EACH GROUP name: 'AUG', shadow: false, data: [ { y: 66, color: '#92D050' }, { y: 55, color: 'red' }, { y: 78, color: '#92D050' }, { y: 55, color: 'red'} ] } Here how can I apply codition like y: > 60 回答1: You can iterate for each element and modify SVG parameter like fill. http://jsfiddle.net/CaPG9/ var max = 200; $.each(chart
