Question

我只是想知道如何根据数据库获取特定数据列

-- | internally sets the initial state
-- | to give the illusion that no state is being passed,
-- | when in fact, the state is set inside the function.
start = 
    -- | calls the start below, not self
    -- | this is tail recursive; initial state 
    -- | is provided, []
    start []

    where 
        -- | this start carries the state along with it
        start initialState = do {
            putStrLn "Enter a number: ";
            raw_input <- getLine;

            -- | stop if ":q" entered.
            if (raw_input == ":q") then
                return ()
            else do { 
                num <- pure (read raw_input :: Int);
                newState <- pure (initialState ++ [num]);
                putStrLn (show newState);
                start newState;
            }            
        }

main = 
    start

然而，使用dotnet的图形没有显示，但是像这样。

当我使用浏览器检查元素时

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;

有什么方法可以解决这个问题吗？非常感谢你

更新：我从具有类似条件enter image description here

的sql数据库中获取此信息

另一个更新：这是本案的完整编码

    $(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' }]
    });
});

然后是dotnetchart

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;
    }

添加代码后，结果就像这样

    {
        GetDataDetail();

        //Binding data to Chart
        DotNet.Highcharts.Highcharts chartColumnDetail = new DotNet.Highcharts.Highcharts("chartColumnDetail").InitChart(new Chart

Answer 1

更新 2 ：

你可以像这样形成数据结果：

     List<object[]> returnColumnList = new List<object[]>();
string json = string.Empty;
var returnObject = new List<object>();
returnColumnList.Add(new object[]  { "Depart" , "123", "345"  });
returnColumnList.Add(new object[] { "Depart", "123", "345" });

foreach (var item in returnColumnList)
{

returnObject.Add(new {name = item.GetValue(0), data = (new object[] {item.GetValue(1) , item.GetValue(2)})});

}

json = new JavaScriptSerializer().Serialize(returnObject);

列表项

系列设置不正确。

请这样做：

series: [{
            name: 'DO-Advisory Department',
            data: [15, 32]
        }, {
            name: 'EDP Department',
            data: [26, 5]
        }, {
            name: 'Enterprise Infrastructure Services Department',
            data: [8, 1]
        }]
