// This property turns on axis values filtering by rules.
xAxisScaleOptions.WorkTimeOnly = true;

// Create a new instance of the worktime rule which will be used to specify
// the worktime displayed on the X-axis.
WorkTimeRule weekdayRule = new WorkTimeRule();
xAxisScaleOptions.WorkTimeRules.Add(weekdayRule);
// Specify one or more work intervals of this rule.
weekdayRule.WorkIntervals.Add(new TimeInterval(09, 00, 00, 19, 00, 00));
// Add weekdays on which this rule should be applied.
weekdayRule.Weekdays = Weekday.Monday | Weekday.Tuesday | Weekday.Wednesday 
        | Weekday.Thursday | Weekday.Friday;

WorkTimeRule dateRule = new WorkTimeRule();
xAxisScaleOptions.WorkTimeRules.Add(dateRule);
dateRule.WorkIntervals.Add(new TimeInterval(12, 00, 00, 16, 00, 00));
// Besides Weekdays, you can specify the Date 
// on which this rule should be applied.
dateRule.Date = new DateTime(2017, 1, 1);

        Or Weekday.Thursday Or Weekday.Friday
