如何将ColumnBar系列设置为图表-Java 学习之路

我想投影具有给定宽度的列（ei从16-05-03 12:00:00到16-07-26 12:00:00）并且它沿x轴投影（ei标签bool，int， long，bool，int long）（见下图） .

enter image description here

为此，我有2个图表区域都具有相同的参数 .

private void AddChartAreas(string name)
{
        // AxisX
        chart1.ChartAreas.Add(name);
        chart1.ChartAreas[name].AxisX.MajorGrid.Enabled = false;
        chart1.ChartAreas[name].AxisX.Interval = 1;

        // AxisY
        chart1.ChartAreas[name].AxisY.ScrollBar.Enabled = true;
        chart1.ChartAreas[name].AxisY.ScaleView.Zoomable = true;
        chart1.ChartAreas[name].AxisY.MajorGrid.Enabled = false;
        chart1.ChartAreas[name].AxisY.LabelStyle.Format = "yyyy-MM-dd hh:mm:ss";

        chart1.ChartAreas[name].AxisY.Interval = 0;
        chart1.ChartAreas[name].AxisY.IntervalType = DateTimeIntervalType.Years;
        minDate = new DateTime(2016, 01, 01, 00, 00, 00, 000);
        maxDate = new DateTime(2016, 12, 01, 00, 00, 00, 000); // or DateTime.Now;
        chart1.ChartAreas[name].AxisY.Minimum = minDate.ToOADate();
        chart1.ChartAreas[name].AxisY.Maximum = maxDate.ToOADate();
        chart1.ChartAreas[name].AxisY.LabelStyle.IsEndLabelVisible = true;
        chart1.ChartAreas[name].AxisY.IsLabelAutoFit = true;
        chart1.ChartAreas[name].AxisY.LabelStyle.ForeColor = Color.Yellow;

        chart1.ChartAreas[name].Axes[0].Enabled = AxisEnabled.False;
        chart1.ChartAreas[name].Axes[1].Enabled = AxisEnabled.False;

        chart1.ChartAreas[name].BackColor = Color.Transparent;
        chart1.ChartAreas[name].Position.Height = 100;
        chart1.ChartAreas[name].Position.Width = 100;
        chart1.ChartAreas[name].InnerPlotPosition.Height = 90;
        chart1.ChartAreas[name].InnerPlotPosition.Width = 80;
        chart1.ChartAreas[name].InnerPlotPosition.X = 10;
}

第一个图表区域（ bar series ）创建如下：

var series = new Series { 
             Name = "S1", 
             Color = Color.LightSlateGray, 
             ChartType = SeriesChartType.Bar
};

chart1.Series.Add(series);

第二个图表区域（ range column series ）：

var series = new Series { 
                 Name = "S2", 
                 Color = Color.LightSlateGray, 
                 ChartType = SeriesChartType.RangeColumn
};

chart1.Series.Add(series);

要为 bar series 添加点，只需为x，y绑定2个列表：

var lables = new string[6];
        var values = new DateTime[6];

        minDate = new DateTime(2016, 01, 01, 00, 00, 00, 000); 

        // Dummy data
        lables[0] = "bool";
        lables[1] = "int";
        lables[2] = "long";
        lables[3] = "bool";
        lables[4] = "int";
        lables[5] = "long";

        // Dummy data
        values[0] = minDate.AddMonths(10);
        values[1] = minDate.AddMonths(10);
        values[2] = minDate.AddMonths(10);
        values[3] = minDate.AddMonths(10);
        values[4] = minDate.AddMonths(10);
        values[5] = minDate.AddMonths(10);

        // Simply bind 2 lists
        series[0].Points.DataBindXY(lables, values);

对于 column range series ：

pointIndex = series[1].Points.AddXY(values2[1], values2[5]);

现在它看起来像这样：

如何使它看起来像第一张图片 .

我想出了一个解决方案 .

而不是 range column 我制作 range bar 系列并将 PointWidth 设置为 5 ：

var series = new Series { 
                 Name = "S2", 
                 Color = Color.LightSlateGray, 
                 ChartType = SeriesChartType.Rangebar
};

series["PointWidth"] = "5";

chart1.Series.Add(series);

比绘图时：

minDate = new DateTime(2016, 01, 01, 00, 00, 00, 000); 

values2[0] = minDate.AddMonths(1);    
values2[1] = minDate.AddMonths(2);

pointIndex = series2.Points.AddXY(values2[1], values2[1]);

这将给我我想要的结果 .
