【中文标题】尝试创建动态 Dundas Stackedarea 图【英文标题】:Trying to create a dynamic Dundas Stackedarea chart 【发布时间】:2015-10-19 18:30:49 【问题描述】:下午好。我尝试进行研究,但尚未找到任何有此示例的人,我通常不会寻求帮助,我只是想通了,但是这个正在杀死我!我正在尝试动态创建堆积面积图,我已经可以创建动态面积图,但我一生都无法弄清楚如何获得堆积面积图来堆叠系列。我在excel中做了类似的东西,我可以让它很好地绘制图表,但它不是动态的。 我有这样排列的数据: How the data is laid out
这就是我希望图表的外观: How I want the chart to look
如何将数据与类别或我需要做的任何事情相关联?我有一个数组中的数据,但我似乎无法弄清楚如何让图表堆叠。任何人都可以帮忙吗?如果您需要更多信息,请询问,我知道我没有包含我的代码,主要是因为它非常丑陋且冗长,但如果有人需要,可以尝试压缩一下并简化。
我的代码在下面(也许这会有所帮助,即使它很丑)
For tmpatozgroup = 1 To 1
Dim chart1 As New Chart()
chart1.ID = "chrt-" & tmpatozgroup & "-" & atozser
Dim seriesperrow As Integer
Dim chartArea1 As New ChartArea()

' Set the ChartArea properties
chartArea1.Name = "Default"
chartArea1.BackColor = System.Drawing.Color.LightGray
chartArea1.AxisX.LabelsAutoFit = False
chartArea1.AxisX.LabelStyle.FontAngle = -45
chartArea1.Area3DStyle.Enable3D = True
chart1.ChartAreas.Add(chartArea1)
Dim series1 As New Series()
series1.Name = tblGrouping1(tmpatozgroup, 0)
chart1.Series.Add(series1)
chart1.Legends.Clear()
If Not IsNothing(tblGrouping1(tmpatozgroup, 0)) Then
For tmpatozgroup2 = 1 To 9
Dim legend1 As New Legend()
Dim sername As String

'need to tear the current row out of the array and place in tmpseries

Next

If serformat = "###,###,##0" Then serformat = "0" : tooltipformat = "#,#"
ser.Points(i2 - 1).ToolTip = ser.Points(i2 - 1).AxisLabel & " : #VALY" & tooltipformat
Next
chart1.ChartAreas(0).AxisX.Interval = 1
chart1.ChartAreas(0).AxisX.LabelStyle.Interval = 1
chart1.ChartAreas(0).AxisX.Title = "test" 'chrtXAxisName
chart1.ChartAreas(0).AxisY.Title = sername
chart1.ChartAreas(0).AxisY.LabelStyle.Format = serformat
chart1.Palette = ChartColorPalette.Dundas
Next
End If
Next
If seriesonrow = seriesperrow Or seriesonrow = 0 Then
tr = New TableRow
tr.CssClass = "charts column"
tr.Style("display") = "none"
End If
td = New TableCell
td.HorizontalAlign = HorizontalAlign.Center
td.ColumnSpan = 6 / seriesperrow
td.Controls.Add(chart1)
tr.Cells.Add(td)
tblReport.Rows.Add(tr)
chart1 = Nothing
End If
Next
提前致谢! 稍后
【问题讨论】:
这是用于 WinForms 的吗?网络表单? WPF? 抱歉,目前在aspx,VB.net,dundas.charting.webcontrol是命名空间,我猜是webforms。 我打算建议System.Web.UI.DataVisualization.Charting
具有 StackedArea
图表类型,但听起来你已经在使用其他东西了。
另外,请在您的问题中添加适当的标签,以便您获得适当的帮助。我不碰任何上面写着“VB”的东西......:O)
你会碰巧有一个该命名空间的堆叠区域的示例吗?我对登打士并不死心,可以轻松切换。至于标记它,由于 C# 和 VB 如此接近并且有这么多转换器,我不介意在 C# 中提供示例(如果它们可用的话),大多数时候所有东西的好示例都在 C# 中,甚至 MS 也喜欢给出 C# 中的示例,所以我习惯于转换。感谢您提供的任何帮助!
【参考方案1】:
这是一个示例:
<asp:Chart ID="Chart1" runat="server" Width="600px">
<Series>
<asp:Series Name="Series1" ChartType="StackedArea">
<Points>
<asp:DataPoint XValue="1" YValues="10" />
<asp:DataPoint XValue="2" YValues="20" />
<asp:DataPoint XValue="3" YValues="30" />
<asp:DataPoint XValue="4" YValues="15" />
</Points>
</asp:Series>
<asp:Series ChartArea="ChartArea1" ChartType="StackedArea" Name="Series2">
<Points>
<asp:DataPoint XValue="1" YValues="20" />
<asp:DataPoint XValue="2" YValues="40" />
<asp:DataPoint XValue="3" YValues="60" />
<asp:DataPoint XValue="4" YValues="45" />
</Points>
</asp:Series>
</Series>
<ChartAreas>
<asp:ChartArea Name="ChartArea1">
<AxisY>
<MajorGrid LineColor="DarkGray" LineDashStyle="Dot" />
</AxisY>
<AxisX>
<MajorGrid LineColor="DarkGray" LineDashStyle="Dot" />
</AxisX>
</asp:ChartArea>
</ChartAreas>
</asp:Chart>
编辑:使用代码隐藏:
protected void Page_Load(object sender, EventArgs e)
Chart chart1 = new Chart();
ChartArea area1 = new ChartArea("Area1");
Series series1 = new Series();
series1.ChartType = SeriesChartType.StackedArea;
series1.Points.Add(new DataPoint XValue = 1, YValues = new double[] 10 );
series1.Points.Add(new DataPoint XValue = 2, YValues = new double[] 20 );
series1.Points.Add(new DataPoint XValue = 3, YValues = new double[] 30 );
series1.Points.Add(new DataPoint XValue = 4, YValues = new double[] 15 );
series1.ChartArea = "Area1";
Series series2 = new Series();
series2.ChartType = SeriesChartType.StackedArea;
series2.Points.Add(new DataPoint XValue = 1, YValues = new double[] 20 );
series2.Points.Add(new DataPoint XValue = 2, YValues = new double[] 40 );
series2.Points.Add(new DataPoint XValue = 3, YValues = new double[] 60 );
series2.Points.Add(new DataPoint XValue = 4, YValues = new double[] 45 );
series2.ChartArea = "Area1";
chart1.ChartAreas.Add(area1);
chart1.Series.Add(series1);
chart1.Series.Add(series2);
Controls.Add(chart1);
编辑 2:添加图例:
protected void Page_Load(object sender, EventArgs e)
Chart chart1 = new Chart();
ChartArea area1 = new ChartArea("Area1");
Legend legend1 = new Legend("Legend1");
legend1.Docking = Docking.Top;
legend1.Alignment = System.Drawing.StringAlignment.Center;
Series series1 = new Series("Bought");
series1.ChartType = SeriesChartType.StackedArea;
series1.Points.Add(new DataPoint XValue = 1, YValues = new double[] 10 );
series1.Points.Add(new DataPoint XValue = 2, YValues = new double[] 20 );
series1.Points.Add(new DataPoint XValue = 3, YValues = new double[] 30 );
series1.Points.Add(new DataPoint XValue = 4, YValues = new double[] 15 );
series1.ChartArea = "Area1";
series1.Legend = "Legend1";
Series series2 = new Series("Sold");
series2.ChartType = SeriesChartType.StackedArea;
series2.Points.Add(new DataPoint XValue = 1, YValues = new double[] 20 );
series2.Points.Add(new DataPoint XValue = 2, YValues = new double[] 40 );
series2.Points.Add(new DataPoint XValue = 3, YValues = new double[] 60 );
series2.Points.Add(new DataPoint XValue = 4, YValues = new double[] 45 );
series2.ChartArea = "Area1";
series2.Legend = "Legend1";
chart1.ChartAreas.Add(area1);
chart1.Legends.Add(legend1);
chart1.Series.Add(series1);
chart1.Series.Add(series2);
Controls.Add(chart1);
【讨论】:
非常感谢。你会碰巧有一个动态制作的例子吗?我在这里看到了它是如何工作的,但是如果我想在代码中动态地制作它,然后将它添加到页面中,你有任何代码吗?我已经添加了命名空间,但我还不知道如何用它制作图表。 我现在没有,但它看起来很像您在帖子中所做的。 非常感谢!!!这一直在杀死我!会试试这个,也许我只是在尝试这样做时很愚蠢,这在我的脑海中是有道理的,但当它出现时却没有。 好的,我明白你有什么。但是我有一个问题,如果让我们说 1,2,3,4 是 xaxis 标签,但实际的 series1 被称为“bought”,而 series2 被称为“sold”,那怎么能显示出来,这就是我的问题所在发生。我在我的代码中发现了一些已修复的问题,但我无法弄清楚如何让这部分工作。 好的,再次感谢,我想我明白了,我想太多了,我相信。现在弄清楚如何让它在我的代码中工作。以上是关于尝试创建动态 Dundas Stackedarea 图的主要内容,如果未能解决你的问题,请参考以下文章
