MsChart 堆叠柱状图间隔如何取消

Question

目前有一个项目需要使用堆叠柱形图准备使用微软自带的MSChart,x轴是时间类型的,一分钟一个堆叠图,但是现在有个问题就是每组堆叠图中间都有一个间隔,因为我x轴是时间这个间隔有时候会被认为是缺少数据,所以么设置可以把这个间隔取消?

Hi Z_H,

为了避免这种情况，你可以将X轴对应的DateTime类型转换为string类型。

    chart1.Series.Clear();
    // The date Xaxis
    List<DateTime> time = new List<DateTime>() { new DateTime(2019, 3, 1, 7, 0, 0), new DateTime(2019, 3, 1, 7, 1, 0), new DateTime(2019, 3, 1, 7, 6, 0) };
    List<string> timestring = new List<string>();
    // convert the date to string
    foreach (DateTime t in  time)
    {
        timestring.Add(t.ToShortTimeString());
    }
    // Add series
    List<string> products = new List<string>() { "A", "B", "C", "D" };
    for (int i = 0; i < products.Count; i++)
    {
        Series series = new Series();
        series.Name = products[i];
        series.ChartType = SeriesChartType.StackedColumn;
        this.chart1.Series.Add(series);
        chart1.Series[i].XValueType = ChartValueType.DateTime;
    }
    // Bind data
    int[][] scores = new int[3][] { new int[] { 1, 2, 3, 4 }, new int[] { 3, 3, 3, 4 }, new int[] { 5, 2, 3, 4 } };
    for (int i = 0; i < products.Count; i++)
    {
        for (int j = 0; j < scores.Length; j++)
            this.chart1.Series[i].Points.AddXY(timestring[j], scores[j][i]);
    }

测试结果如下：

抱歉由于我账号没有验证无法发送图片,可能是我表述不清,我的意思是取消掉每组柱形图之间的白色间隔,就像你的测试结果,我是想取消7:00 AM与7:01AM两组柱形图之间的白色间隔,也就是让两组柱形图紧挨着

Hi Z_H,

你可以尝试使用以下代码来设置series的宽度。

    chart1.Series[i]["PixelPointWidth"] = "80";

这种做法是需要根据当前控件尺寸以及绘制的数据数量计算出每个数据占据的宽度,目前我也并未找到更好的做法,就先采取这个措施吧.
