本示例演示了如何从 轴范围 中去除非工作日 (周末和节假日)，这是通过 AxisBase.WorkdaysOnly 和 AxisBase.WorkdaysOptions 属性来实现的。

AxisX axisX = ((XYDiagram)chartControl1.Diagram).AxisX;

// Exclude holidays from the axis scale.
axisX.WorkdaysOnly = true;

// Specify custom working days.
axisX.WorkdaysOptions.Workdays = Weekday.Sunday | Weekday.Monday | Weekday.Tuesday |
    Weekday.Wednesday | Weekday.Thursday | Weekday.Friday;

// Specify holidays
axisX.WorkdaysOptions.Holidays.AddRange(new KnownDate[] {
    new KnownDate("Custom Holiday 1", new DateTime(1994, 3, 2, 0, 0, 0, 0)),
    new KnownDate("Custom Holiday 2", new DateTime(1994, 4, 2, 0, 0, 0, 0))});

// Specify strict working days.
// Thay will have a priority over the holidays specified.
axisX.WorkdaysOptions.ExactWorkdays.Add(
    new KnownDate("Community Work Day", new DateTime(1994, 3, 2, 0, 0, 0, 0)));
