C# 图表：删除空列并显示所有列名

如何解决C# 图表：删除空列并显示所有列名

我想删除空列，我的意思是：如果一列的总值为 0 --> 删除其空间和名称。 我还想显示 X 轴下方的每一列名称。 那可能吗？ 这是我的代码示例和我现在拥有的 png。

chart1.Series.Add("Series1");
chart1.Series["Series1"].ChartType = System.Windows.Forms.DataVisualization.Charting.SeriesChartType.StackedColumn;
chart1.Series["Series1"].Points.AddXY("column1",6);
chart1.Series["Series1"].Points.AddXY("column2",0);
chart1.Series["Series1"].Points.AddXY("column3",11);
chart1.Series["Series1"].Points.AddXY("column4",6);
chart1.Series["Series1"].Points.AddXY("column5",0);
chart1.Series["Series1"].Points.AddXY("column6",0);
chart1.Series["Series1"].Points.AddXY("column7",6);
chart1.Series["Series1"].Points.AddXY("column8",0);
chart1.Series["Series1"].Points.AddXY("column9",2 );
chart1.Series["Series1"].Points.AddXY("column10",6);
chart1.Series["Series1"].Points.AddXY("column11",0);
chart1.Series["Series1"].Points.AddXY("column12",5);
chart1.Series["Series1"].Points.AddXY("column13",0);
chart1.Series["Series1"].Points.AddXY("column14",0);

chart1.Series.Add("Series2");
chart1.Series["Series2"].ChartType = System.Windows.Forms.DataVisualization.Charting.SeriesChartType.StackedColumn;
chart1.Series["Series2"].Points.AddXY("column1",3);
chart1.Series["Series2"].Points.AddXY("column2",0);
chart1.Series["Series2"].Points.AddXY("column3",7);
chart1.Series["Series2"].Points.AddXY("column4",0);
chart1.Series["Series2"].Points.AddXY("column5",0);
chart1.Series["Series2"].Points.AddXY("column6",3);
chart1.Series["Series2"].Points.AddXY("column7",5);
chart1.Series["Series2"].Points.AddXY("column8",3);
chart1.Series["Series2"].Points.AddXY("column9",6);
chart1.Series["Series2"].Points.AddXY("column10",3);
chart1.Series["Series2"].Points.AddXY("column11",0);
chart1.Series["Series2"].Points.AddXY("column12",6);
chart1.Series["Series2"].Points.AddXY("column13",0);
chart1.Series["Series2"].Points.AddXY("column14",3);

chart1.Titles.Add("Series View by StackedColumns"); 
chart1.Titles[0].Font = new System.Drawing.Font("consolas",15f);   
chart1.Legends[0].Font = new System.Drawing.Font("consolas",15f);          
chart1.ChartAreas[0].AxisX.LabelStyle.Enabled = true;
chart1.ChartAreas[0].AxisX.MajorGrid.Enabled = false;
chart1.ChartAreas[0].AxisY.MajorGrid.Enabled = false;

解决方法

谢谢，首先要查看所有列名只需添加以下代码行：

chart1.ChartAreas[0].AxisX.Interval = 1;

然后遍历点并在总数为零时删除值：

for (int i = 0; i < chart1.Series["Series1"].Points.Count;i++)
{
    if(chart1.Series["Series1"].Points[i].YValues[0] + 
       chart1.Series["Series2"].Points[i].YValues[0] == 0)
    {
        chart1.Series["Series1"].Points.Remove(chart1.Series["Series1"].Points[i]);
        chart1.Series["Series2"].Points.Remove(chart1.Series["Series2"].Points[i]);
    }
}
