有没有一种方法可以在MSChart折线图中对齐标签？

Question

I am using MSChart in Visual Studio 2013 and am getting some really weird results. On a line chart, when graphing the points, the labels show lower valued points as higher on the chart, which is visually confusing. See the following:

The chart labels are set as follows:

        recentFailureChart.Series["FailureCount"].BorderWidth = 3;
            recentFailureChart.Series["FailureCount"].Color = Color.Red;
            recentFailureChart.Series["FailureCount"].LabelBackColor = Color.Red;
            recentFailureChart.Series["FailureCount"].LabelBorderColor = Color.Black;
            recentFailureChart.Series["FailureCount"].LabelBorderDashStyle = ChartDashStyle.Solid;
            recentFailureChart.Series["FailureCount"].LabelBorderWidth = 1;
            recentFailureChart.Series["FailureCount"].LabelForeColor = Color.White;
        SmartLabelStyle smartLabel = new SmartLabelStyle();
        smartLabel.AllowOutsidePlotArea = LabelOutsidePlotAreaStyle.Partial;
        smartLabel.IsMarkerOverlappingAllowed = true;
        recentFailureChart.Series["FailureCount"].SmartLabelStyle = smartLabel;

in the constructor and in the function adding the points:

        recentFailureChart.Series["FailureCount"].Points.InsertY(0, failCount);
        recentFailureChart.Series["FailureCount"].Points[0].Font = labelFont;

Any ideas on how to get them in the correct order, or even over the points themselves?

Answer 1

我看不到上面的“图表图像”有什么问题，点14和12正确地绘制在5、3和1较低点的上方。我注意到的唯一一点是，并不是所有的点都在图表中可见，可以通过使用Chart1.ChartAreas（0）.AxisY.Maximum = 100将Y轴的最大值设置为较高的值（例如100）来更改此值。

I believe the properties you are looking for are these:

MaxMovingDistance  
MinMovingDistance  
MovingDirection  
AllowOutsidePlotArea  

A. Set AllowOutsidePlotArea if it is acceptable for the label to overlap the X-Axis.

B. Set MovingDirection to Top in order to force all labels to be displayed over the DataPoint.

C. You could also make the X-Axis cross the Y-Axis on -2 or something similar, making room for the smartlabels inside the plotarea.
