DotNet.Highcharts:未根据正确日期绘制成本 [英] DotNet.Highcharts: Cost not plotted against the correct date

问题描述

我正在创建一个

如您所见，正在创建系列，但它们是根据数组中的数字而不是应链接到的日期绘制的.

我不确定我离解决方案有多近或多远，但我们感谢任何帮助.这是我的传入数据表

这是我的支出数据表

真的不知道该怎么做.非常感谢任何信息

解决方案

您的 Y 值与 X 值完全脱节.为了实现您想要的，您需要按如下方式重组您的数据:

 DateTime dt = new DateTime(2016, 2, 27);Highcharts 图表 = new Highcharts("graph").SetTitle(new Title { Text = "Incoming Stats" }).SetXAxis(new XAxis { Type = AxisTypes.Datetime }).SetYAxis(new YAxis { Title = new YAxisTitle { Text = "Amount Incoming" } }).SetSeries(新[]{新系列 { Name = "inc", Data = new Data(new object[,] {{dt , 23 },{dt.AddDays(1) , 223 },{dt.AddDays(2) , 51 },{dt.AddDays(11) , 200 }, }) },新系列 { Name = "exp", Data = new Data(new object[,] {{dt.AddDays(5) , 100 },{dt.AddDays(6) , 23 },{dt.AddDays(11) , 23 },{dt.AddDays(19) , 35 },{dt.AddDays(35), 288 }, }) }});

如何动态执行:

 object[,] data1 = new object[Dt.Rows.Count, 2];for (int i = 0; i 

从数据库中检索到的数据:

I'm creating a DotNet.Highcharts chart that is using data from two tables: Expenditures and Incomings. I am using an SQL statement to create a DataTable for each. The first (for Incomings) called Dt contains IncCost and IncDate. The second (for Expenditures) called Dt2 contains ExpCost and ExpDate.

I am able to plot IncCost against IncDate and ExpCost against ExpDate. The problem arises when I try to concatenate IncDate and ExpDate (final) as the cost for IncCost and ExpCost is plotting against the position of the date in (final), and not the actual date it is related to.

Here are the calls I use to create each DataTable:

SqlDataAdapter Adp = new SqlDataAdapter("select CONVERT(DATETIME, IncDate, 103) AS IncDate, SUM(IncCost) AS IncCost from Incomings GROUP BY CONVERT(DATETIME, IncDate, 103) ORDER BY CONVERT(DATETIME, IncDate, 103)", con);

SqlDataAdapter Adp2 = new SqlDataAdapter("select CONVERT(DATETIME, ExpDate, 103) AS ExpDate, SUM(ExpCost) AS ExpCost from Expenditures GROUP BY CONVERT(DATETIME, ExpDate, 103) ORDER BY CONVERT(DATETIME, ExpDate, 103)", con);

Here is the code for calling each of these from the datatable

var dateArr = Dt.AsEnumerable().Select(r => r.Field<DateTime>("IncDate")).ToArray();
var objectArr = Dt.AsEnumerable().Select(r => r.Field<object>("IncCost")).ToArray();

var dateArr2 = Dt2.AsEnumerable().Select(r => r.Field<DateTime>("ExpDate")).ToArray();
var objectArr2 = Dt2.AsEnumerable().Select(r => r.Field<object>("ExpCost")).ToArray();   

var res = dateArr.Concat(dateArr2).ToArray();
var final = res.Select(d => d.ToString(@"dd/MM/yyyy")).ToArray();

And here is the code I use to create my highchart:

Highcharts chart = new Highcharts("graph")
  .SetTitle(new Title { Text = "Incoming Stats" })
  .SetXAxis(new[] { new XAxis { Categories = final } })
  .SetYAxis(new YAxis { Title = new YAxisTitle { Text = "Amount Incoming" } })
  .SetSeries(new[]
    {
      new Series { Name = "inc", Data = new Data(objectArr)},
      new Series { Name = "exp", Data = new Data(objectArr2) }
    });

As you can see, the series are being created but they are being plotted against the number in the array, and not against the date it should be linked to.

I'm not sure how close or far I am to a solution but any help is appreciated. Here is my incomings datatable

Here is my expenditure datatable

Genuinely don't know how to go about this. any information is greatly appreciated

解决方案

Your Y values are completely disconnected from X values. In order to achieve what you want, you need to restructure your data as below:

        DateTime dt = new DateTime(2016, 2, 27);

        Highcharts chart = new Highcharts("graph")
           .SetTitle(new Title { Text = "Incoming Stats" })
           .SetXAxis(new XAxis { Type = AxisTypes.Datetime })
           .SetYAxis(new YAxis { Title = new YAxisTitle { Text = "Amount Incoming" } })
           .SetSeries(new[]
             {
              new Series { Name = "inc", Data = new Data(new object[,] { 
                  {dt , 23 }, 
                  {dt.AddDays(1) , 223 }, 
                  {dt.AddDays(2) , 51 }, 
                  {dt.AddDays(11) , 200 }, }) },
              new Series { Name = "exp", Data = new Data(new object[,] { 
                  {dt.AddDays(5) , 100 }, 
                  {dt.AddDays(6) , 23 }, 
                  {dt.AddDays(11) , 23 }, 
                  {dt.AddDays(19) , 35 }, 
                  {dt.AddDays(35) , 288 }, }) }
             });

EDIT: How to do it dynamically:

        object[,] data1 = new object[Dt.Rows.Count, 2];
        for (int i = 0; i < Dt.Rows.Count; i++)
        {
            data1[i, 0] = Dt.Rows[i]["IncDate"];
            data1[i, 1] = Dt.Rows[i]["IncCost"];
        }

        object[,] data2 = new object[Dt2.Rows.Count, 2];
        for (int i = 0; i < Dt2.Rows.Count; i++)
        {
            data2[i, 0] = Dt2.Rows[i]["ExpDate"];
            data2[i, 1] = Dt2.Rows[i]["ExpCost"];
        }

        Highcharts chart = new Highcharts("graph")
           .SetTitle(new Title { Text = "Incoming Stats" })
           .SetXAxis(new XAxis { Type = AxisTypes.Datetime })
           .SetYAxis(new YAxis { Title = new YAxisTitle { Text = "Amount Incoming" } })
           .SetSeries(new[]
             {
                    new Series { Name = "inc", Data = new Data(data1) },
                    new Series { Name = "exp", Data = new Data(data2) }
             });
