**Inheritance:**
java.lang.Object
```
public class TimeLineHelper
```

TimeLineHelper to set property of timeline shape. Compatibility shell over [TimeLineProperties](../../com.aspose.diagram/timelineproperties): the public API is unchanged (plus getters for the previously write-only properties), the cell access is delegated to the properties class, and [refreshTimeLine()](../../com.aspose.diagram/timelinehelper\#refreshTimeLine--) is rewritten:

    | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
    | /// The begin/end date text shapes are updated by position without skipping the last /// child, so the end-date text shape is updated as well. ///                                                                                 |
    | /// Master-instance markers (milestones, intervals) inside the period keep their /// field \\u9225?the old code overwrote every master-instance child field with the start /// date. Out-of-range markers are deleted instead. /// |
    | /// Previously generated interim ticks are removed and regenerated with the interim /// User cells (visTLShape, visInterimType) that real timeline ticks carry, so they /// render as timeline ticks in Visio. ///                 |
    | /// Year-scale ticks land on January 1 boundaries, so ranges that cross a year /// boundary are no longer empty for spans under one year. ///                                                                                      |
