排队X轴标签用图表列（ASP.Net图表控件） [英] Line up X axis labels with chart columns (ASP.Net Chart control)

问题描述

我试图让使用具有在X轴上的具体数值的ASP.Net图表控件和Y轴的频率计数的图表。下面是我从图表框架，我想更换一个例子：

在上面的例子中，X轴标签排队与列。但是，随着ASP.Net图表控制的，而不是标记从而重新present这些特定值的列（例如，1492，2984），控制是标签在圆形的间隔，而不与列排队（例如2000年，4000 ），你可以看到如下：

我发现，推荐设置其他类似的帖子在 ChartArea.AxisX.Interval 1。我试过了，但随后的X轴标签出于某种原因，你可以消失见下图：

下面是code我使用创建和填充图（减去设置不同的颜色属性）：

 的DataTable newDt = GetChartDataTable（）;
chart.DataSource = newDt;
chart.Series.Add（系列1）;
chart.Series [系列1] = YValueMembers频率。
chart.Series [系列1] XValueMember =RoundedValue。
chart.ChartAreas [ChartArea1] AxisX.Title =kbps的。
。chart.ChartAreas [ChartArea1] = AxisX.TitleFont新字体（无衬线，10，FontStyle.Bold）;
chart.ChartAreas [ChartArea1] = AxisY.Title频率。
。chart.ChartAreas [ChartArea1] = AxisY.TitleFont新字体（无衬线，10，FontStyle.Bold）;
chart.Titles [标题1] =文字chartTitle。
。chart.Titles [标题1] =字体新字体（无衬线，10，FontStyle.Bold）;
chart.Series [系列1] =图表类型System.Web.UI.DataVisualization.Charting.SeriesChartType.Column。
chart.Series [系列1] [ShowMarkerLines] =真;
chart.DataBind（）;
 

解决方案

您应该 IsXValueIndex 设置为真正。

就像这样：结果
chart.Series [系列1] = IsXValueIndexed真实;

例如：

  //创建系列
系列系列1 =新系列（系列1）;//设置图表类型
series1.ChartType = SeriesChartType.Column;//添加一些要点
series1.Points.AddXY（1492，12）;
series1.Points.AddXY（2984，0）;
series1.Points.AddXY（4476，1）;
series1.Points.AddXY（5968，2）;
series1.Points.AddXY（7460，2）;
series1.Points.AddXY（8952，12）;
series1.Points.AddXY（10444，4）;
series1.Points.AddXY（11936，3）;
series1.Points.AddXY（13428，3）;
series1.Points.AddXY（14920，5）;
series1.Points.AddXY（16412，1）;Chart1.Series.Add（系列1）;Chart1.Width = 600;
Chart1.Height = 600;//系列视觉
series1.YValueMembers =频率;
series1.XValueMember =RoundedValue;
series1.BorderWidth = 1;
series1.ShadowOffset = 0;
series1.Color = Drawing.Color.Red;
series1.IsXValueIndexed = TRUE;//设置X轴
。Chart1.ChartAreas（ChartArea1）AxisX.IsMarginVisible = TRUE;
Chart1.ChartAreas（ChartArea1）AxisX.Interval = 1。
Chart1.ChartAreas（ChartArea1）AxisX.Maximum = Double.NaN。
Chart1.ChartAreas（ChartArea1）AxisX.Title =kbps的。
。Chart1.ChartAreas（ChartArea1）AxisX.TitleFont =新的字体（无衬线，10，FontStyle.Bold）;//设置Y轴
Chart1.ChartAreas（ChartArea1）AxisY.Interval = 2。
Chart1.ChartAreas（ChartArea1）AxisY.Maximum = Double.NaN。
Chart1.ChartAreas（ChartArea1）AxisY.Title =频率。
。Chart1.ChartAreas（ChartArea1）AxisY.TitleFont =新的字体（无衬线，10，FontStyle.Bold）;
 

I'm trying to make a chart using the ASP.Net Chart control that has specific numerical values on the X axis and their frequency count on the Y axis. Here is an example of what I want from the charting framework I am replacing:

In the above example, the X axis labels line up with the columns. But, with the ASP.Net Chart control, instead of labeling the columns which represent these specific values (e.g. 1492, 2984), the control is labeling at rounded intervals and not lining up with the columns (e.g. 2000, 4000) as you can see below:

I found other similar postings that recommended setting the ChartArea.AxisX.Interval to 1. I tried that, but then the X axis label disappears for some reason as you can see below:

Here is the code I'm using to create and populate the chart (minus setting various color attributes):

DataTable newDt = GetChartDataTable();
chart.DataSource = newDt;
chart.Series.Add("Series1");
chart.Series["Series1"].YValueMembers = "Frequency";
chart.Series["Series1"].XValueMember = "RoundedValue";
chart.ChartAreas["ChartArea1"].AxisX.Title = "kbps";
chart.ChartAreas["ChartArea1"].AxisX.TitleFont = new Font("Sans Serif", 10, FontStyle.Bold);
chart.ChartAreas["ChartArea1"].AxisY.Title = "Frequency";
chart.ChartAreas["ChartArea1"].AxisY.TitleFont = new Font("Sans Serif", 10, FontStyle.Bold);
chart.Titles["Title1"].Text = chartTitle;
chart.Titles["Title1"].Font = new Font("Sans Serif", 10, FontStyle.Bold);
chart.Series["Series1"].ChartType = System.Web.UI.DataVisualization.Charting.SeriesChartType.Column;
chart.Series["Series1"]["ShowMarkerLines"] = "True";
chart.DataBind();

解决方案

You should set IsXValueIndex to true.

Like this:
chart.Series["Series1"].IsXValueIndexed = true;

Example:

// Creating the series 
Series series1 = new Series("Series1");

// Setting the Chart Types
series1.ChartType = SeriesChartType.Column;

// Adding some points
series1.Points.AddXY(1492, 12);
series1.Points.AddXY(2984, 0);
series1.Points.AddXY(4476, 1);
series1.Points.AddXY(5968, 2);
series1.Points.AddXY(7460, 2);
series1.Points.AddXY(8952, 12);
series1.Points.AddXY(10444, 4);
series1.Points.AddXY(11936, 3);
series1.Points.AddXY(13428, 3);
series1.Points.AddXY(14920, 5);
series1.Points.AddXY(16412, 1);

Chart1.Series.Add(series1);

Chart1.Width = 600;
Chart1.Height = 600;

// Series visual
series1.YValueMembers = "Frequency";
series1.XValueMember = "RoundedValue";
series1.BorderWidth = 1;
series1.ShadowOffset = 0;
series1.Color = Drawing.Color.Red;
series1.IsXValueIndexed = true;

// Setting the X Axis
Chart1.ChartAreas("ChartArea1").AxisX.IsMarginVisible = true;
Chart1.ChartAreas("ChartArea1").AxisX.Interval = 1;
Chart1.ChartAreas("ChartArea1").AxisX.Maximum = Double.NaN;
Chart1.ChartAreas("ChartArea1").AxisX.Title = "kbps";
Chart1.ChartAreas("ChartArea1").AxisX.TitleFont = new Font("Sans Serif", 10, FontStyle.Bold);

// Setting the Y Axis
Chart1.ChartAreas("ChartArea1").AxisY.Interval = 2;
Chart1.ChartAreas("ChartArea1").AxisY.Maximum = Double.NaN;
Chart1.ChartAreas("ChartArea1").AxisY.Title = "Frequency";
Chart1.ChartAreas("ChartArea1").AxisY.TitleFont = new Font("Sans Serif", 10, FontStyle.Bold);
