问题 I have about 6 charts on one page, one of them needs to have a different theme from the other five. I have the themes working individually but the second one initialized is applied to all the charts. Is there a way to specify which theme a chart uses? 回答1: After reading Ricardo's comment I realized I just had to move the setOptions() call inside the $(document).ready call. A much simplified version of my code: Highcharts.theme1 = { chart: { borderWidth: 0, }, }; var chart; $(document).ready

问题 please take a look at this: http://jsfiddle.net/2rNzr/ var chart = new Highcharts.Chart({ chart: { renderTo: 'container' }, xAxis: { categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'] }, series: [{ data: [29.9, '', 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4] }] }); you'll notice that the data has a blank value in it (the second value), which causes the line graph to display incorrectly. Is this a bug? What is the correct

问题 We are using Highcharts and have some complex charts with roughly 75 series within on chart. The series are not used through the whole chart but only for range of three month. So we have about 15 series per year and the overall chart covers five years (makes roughly 15*5 = 75 series). However Highcharts displays all 75 charts within its legend. The goal is to minimize the legend to the visible series only. We are able to determine the related series in JS code and we tried to toggle the

问题 I saw this code: http://jsfiddle.net/AVygG/ I'm curious when is the point that the highchart gets loaded completely? I saw in highcharts documentation that events: load: should do the magic of being able to call the callback function when the highchart is completely loaded. If it were completely loaded, then could I assume that var chart should already have the values when the alert pops? Is that a good basis that the chart is already loaded? The reason I asked is that I'm working on another

问题 I'm just going to hardcode it in using html that is around the graph, I don't want to use the built in. I don't see a "disable: true" option in the API. Can anybody help me out here. How do you disable the title / subtitle in highcharts? (if you simply leave the text blank it still carves out a whitespace in that spot where the title is, i'd like to not have this happen) 回答1: Setting the title text to an empty string is the way to do it. No space is created for the title in that case: without

问题 I have a php page (array.php).

问题 I want show/hide some categories in highcharts using checkbox, can you help me? This is my code so far: var categories = chart.categories[0]; if(categories.graphic.visibility == 'hidden'){ categories.graphic.show(); } else { categories.graphic.hide(); } 回答1: This seems to be a pretty common question in a variety of forms, and with a variety of solutions. I have created a demo to do this in a way that is dynamically built upon a pre-processed category array and series object. It uses the array
