问题 I am using DotNet.Highcharts in my C# program. The data element for series items requires an object[] . The data I’m using is coming from a LINQ method as shown below. The code below also converts the double?[] to a List<object> then to the desired object[] . double?[] data = (from c in context.CTSeries select c.CTDI).Take(1000).ToArray(); List<object> dataList = new List<object>(); foreach (double? ctdi in data) { dataList.Add( Convert.ChangeType(ctdi, typeof(Object))); } object[] dataArray

问题 I want to chart (line) a swimmer competition times over several meets. For the series data I use the php code : $datetime1=date('Y, m, d', strtotime($performances['PERF_DATE']."-1 month")); $datetime2='Date.UTC('.$datetime1.')'; $chrono=strtotime($performances['PERF_DATE']); $data[] = "[$datetime2, $chrono]"; The xAxis timeline is for swim meet dates : xAxis: { type: 'datetime', dateTimeLabelFormats: { day: '%d/%m/%Y'} The yAxis timeline is for the race times : yAxis: { title : { text :

问题 I have a simple shiny application (consisting of two files, server.r and ui.r) which uses the rCharts package with Highcharts. It runs pretty good, but if I choose to make all the bars disappear and then to display them again, they won't rescale. Here is the code, which is based on a simple example provided on rCharts' GitHub: ui.r require(rCharts) options(RCHART_LIB = 'highcharts') shinyUI(pageWithSidebar( headerPanel("App title"), sidebarPanel( helpText('A simple text.') ), mainPanel

问题 I am having several experiments a day storing the error of the experiment and a boolean value (if the result is ok) in elasticsearch. Now, I would like to display the results in a graph (using highchart js). I use an aggregation query like this to receive the aggregated errors for each day including the standard deviation: query: { filtered: { filter: { range : { date: { "gte":"2015-1-1", "lte": "2016-1-1, "time_zone": "+1:00" } } } } }, // Aggregate on the results aggs: { group_by_date: {

问题 Is it at all possible to be able to have a vertically stacked bar chart with negative values (using highcharts). Like this: http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/column-stacked/ series: [{ name: 'John', data: [5, -3, 4, 7, 2] }, { name: 'Jane', data: [2, 2, -31, 2, 1] }, { name: 'Joe', data: [3, 4, 4, 2, 5] }] Unfortunately negative values don't register. This seems to be a solution: http://jsfiddle.net/gh/get/jquery/1.9
