я просто любопытно, как получить конкретный столбец данных на основе базы данныхошибка highchart DotNet, не показывая данные
string[] arrLabel = new string[dt.Rows.Count];
Object[] data = new Object[dt.Rows.Count];
Object[] dataDetail = new Object[dt.Rows.Count];
String[] detail = new String[dt.Rows.Count];
var returnObject = new List<object>();
var returnColumnList = new List<object>();
int i = 0;
foreach (DataRow item in dt.Rows)
{
for (int j = 0; j < 1; j++)
{
returnColumnList.Add(new object[] {item["ATT_WF_STATUS_2"], item["ATT_WF_STATUS_3"]});
}
dataDetail = returnColumnList.ToArray();
returnObject.Add(new object[] { item["DEPARTEMENT"],dataDetail[i]});
arrLabel[i] = ((string)item["DEPARTEMENT"]);
i++;
}
data = returnObject.ToArray();
this.data = data;
this.arrLabel = arrLabel;
однако, графический использованием DotNet не показаны, но как это. 
когда я инспектировать элемент с помощью браузера
$(document).ready(function() {
chartColumnDetail = new Highcharts.Chart({
chart: { renderTo:'chartColumnDetail_container', options3d: { alpha: 10, beta: 0, depth: 50, enabled: true, viewDistance: 25 }, plotShadow: false, type: 'column' },
credits: { enabled: false },
legend: { enabled: true, itemStyle: { color: '#2C3E50' } },
plotOptions: { column: { allowPointSelect: true, colorByPoint: true, cursor: 'pointer', dataLabels: { enabled: true, style: { font:'14px', fontWeight:'bold' } }, depth: 50, showInLegend: true } },
subtitle: { text: 'Grouped by Status' },
title: { text: 'Attendance Analytics From 01 January 2010 Until 15 December 2016' },
tooltip: { formatter: function(){ var sliceIndex =this.point.index; var sliceName = this.series.chart.axes[0].categories[sliceIndex]; return 'The value for <b>' + this.point.name + '</b> is <b>' + this.y +'</b>';} },
xAxis: { categories: ['DO-Advisory Department', 'EDP Department', 'Enterprise Infrastructure Services Department', 'Pre Sales Department', 'Sales Department 1', 'IO-DCOPS Department', 'Human Capital Department'], labels: { align: 'center', style: { font: 'bold 10px Verdana,sans-serif' } } },
yAxis: { min: 0, title: { text: 'Amount' } },
exporting: { buttons: { contextButton: { align: 'center', x: 350, y: -3 } }, enabled: true, scale: 5 },
series: [{ data: [['DO-Advisory Department', [15, 32]], ['EDP Department', [26, 5]], ['Enterprise Infrastructure Services Department', [8, 1]], ['Pre Sales Department',[ 1, 6]], ['Sales Department 1', [1, 3]], ['IO-DCOPS Department',[ 1, 0]], ['Human Capital Department',[1, 0]], name: 'Department' }]
});
});
есть ли способ, чтобы исправить эту проблему? Большое спасибо
Update: я беру это из SQL базы данных, которая имеет этот подобное условие enter image description here
Еще одно обновление: это полное кодирование для этого случая
protected DataTable GetDataDetail()
{
SortedList sl = new SortedList();
DateTime dateFrom = DateTime.ParseExact(Request.Form[txtOldDate.UniqueID], "yyyy-MM-dd", null);
DateTime dateTo = DateTime.ParseExact(Request.Form[txtNewDate.UniqueID], "yyyy-MM-dd", null);
sl.Add("@DATE_FROM-date", dateFrom);
sl.Add("@DATE_TO-date", dateTo);
DataTable dt = new DataTable();
dateFromChart = dateFrom.ToString("dd MMMM yyyy", CultureInfo.InvariantCulture);
dateToChart = dateTo.ToString("dd MMMM yyyy", CultureInfo.InvariantCulture);
dt = bll.GetAttendanceAnalyticsBasedWfStatus(sl);
string[] arrLabel = new string[dt.Rows.Count];
Object[] data = new Object[dt.Rows.Count];
Object[] dataDetail = new Object[dt.Rows.Count];
var returnObject = new List<object>();
List<object[]> returnColumnList = new List<object[]>();
int i = 0;
foreach (DataRow item in dt.Rows)
{
for (int j = 0; j < 1; j++)
{
returnColumnList.Add(new object[] { item["DEPARTEMENT"], item["ATT_WF_STATUS_2"], item["ATT_WF_STATUS_3"] });
}
dataDetail = returnColumnList.ToArray();
returnObject.Add(new object[] { returnColumnList.Select(b => new { name = b.GetValue(0), data = returnColumnList.Select(y => y.GetValue(1) + "," + y.GetValue(2)).ToArray() }).ToArray() });
arrLabel[i] = ((string)item["DEPARTEMENT"]);
i++;
}
jsonSeries = new JavaScriptSerializer().Serialize(returnObject);
Response.Write(jsonSeries);
data = returnObject.ToArray();
this.data = data;
this.arrLabel = arrLabel;
return dt;
}
то dotnetchart

chartContainerColumnDetail.Text = chartColumnDetail.ToHtmlString();
}
после добавления кода, результат будет выглядеть следующим образом

Обратите внимание, что вы выбрали символ в качестве столбца, вы также можете выбрать диаграмму диапазона столбцов на основе того, как вы хотите отображать данные. – FakeisMe
спасибо за ваше краткое объяснение, проблема в том, что я беру это с сервера sql, таблица от пользовательской процедуры –
Я получаю ошибку на GetValue, так как не содержит определения, и на них есть красновато-красное. , я обновлю условие полного кодирования –
