C# 仅显示日期的devexpress xtracharts

我已经创建了一个devexpress图表（v13.2），它在x轴上有datetime，在Y轴上有值

当前在x轴上，它显示如下日期：

但默认情况下，我还需要显示日期和时间，如下所示：

即使x轴编码为从数据库获取日期时间，但它仍然只显示日期而不是时间。 为什么？

请尝试该属性并设置适当的值：

这是一个分两步的过程，在秤上显示日期和时间：

将属性设置为

然后选择Axis.DateTimeScaleOptions属性和自定义设置

(XYDiagram)chartControl1.Diagram).AxisX.DateTimeOptions.Format = DateTimeFormat.General;
(XYDiagram)chartControl1.Diagram).AxisX.DateTimeScaleOptions.GridAlignment = 
                                DevExpress.XtraCharts.DateTimeGridAlignment.Minute;
(XYDiagram)chartControl1.Diagram).AxisX.DateTimeScaleOptions.MeasureUnit = 
                                  DevExpress.XtraCharts.DateTimeMeasureUnit.Minute;

检查以下代码和图表配置，使我能够获得您想要实现的预期结果：

    // This line of code is generated by Data Source Configuration Wizard
    chartDataTableAdapter1.Fill(dbDataSet1.ChartData);
