在 devexpress 图表控件 c# 中设置图表类型 属性

Question

如您所见，我在程序的仪表板中创建了一个图表：

我在 load_form

中使用此代码初始化数据

   chartControlMIVBaseDateTime.DataSource = _materialIssueVoucherRepository.ViewImivBasedOnDates().ToList();


            // Generate a data table and bind the chart to it.

            // Specify data members to bind the chart's series template.
            chartControlMIVBaseDateTime.SeriesDataMember = "Count";
            chartControlMIVBaseDateTime.SeriesTemplate.ArgumentDataMember = "DateTime";
            chartControlMIVBaseDateTime.SeriesTemplate.ValueDataMembers.AddRange(new string[] { "Count" });

计数为数字，但问题是我将图表设置为显示此类演示文稿

但是没用

最终代码

 Series series = new Series("Series1", ViewType.Spline);

            chartControlMIVBaseDateTime.Series.Add(series);

            // Generate a data table and bind the series to it.
            series.DataSource = _materialIssueVoucherRepository.ViewImivBasedOnDates().ToList();

            // Specify data members to bind the series.
            series.ArgumentScaleType = ScaleType.DateTime;
            series.ArgumentDataMember = "DateTime";
            series.ValueScaleType = ScaleType.Numerical;
            series.ValueDataMembers.AddRange(new string[] { "Count" });
