| Name | Description | |
|---|---|---|
 | clearFormats | Clears the formatting of the object. |
| delete | Deletes the object. |
| getBackward | Gets the number of periods (or units on a scatter chart) that the trendline extends backward. |
| getDataLabel | Returns a IDataLabel object that represents the data label associated with the trendline. |
| getDisplayEquation | Gets whether to display the equation for the trendline (True if the equation for the trendline is displayed on the chart, in the same data label as the R-squared value). Setting this property to True automatically turns on data labels. |
| getDisplayRSquared | Gets whether to display the R-squared value (True if the R-squared value of the trendline is displayed on the chart, in the same data label as the equation). Setting this property to True automatically turns on data labels. |
| getFormat | Returns the format for chart elements. |
| getForward | Gets the number of periods (or units on a scatter chart) that the trendline extends forward. |
| getIndex | Returns the index number of the object within the collection of similar objects. |
| getIntercept | Gets the point where the trendline crosses the value axis. |
| getName | Gets the name of the object. |
| getNameIsAuto | Gets if the trendline's name is automatically determined. |
| getOrder | Gets the trendline order (an integer greater than 1) when the trendline type is Polynomial. |
| getParent | Returns the parent object for the specified object. |
| getPeriod | Gets the period for the moving-average trendline. |
| getType | Gets the trendline type. |
| setBackward | Sets the number of periods (or units on a scatter chart) that the trendline extends backward. |
| setDisplayEquation | Sets whether to display the equation for the trendline (True if the equation for the trendline is displayed on the chart, in the same data label as the R-squared value). Setting this property to True automatically turns on data labels. |
| setDisplayRSquared | Sets whether to display the R-squared value (True if the R-squared value of the trendline is displayed on the chart, in the same data label as the equation). Setting this property to True automatically turns on data labels. |
| setForward | Sets the number of periods (or units on a scatter chart) that the trendline extends forward. |
| setIntercept | Sets the point where the trendline crosses the value axis. |
| setName | Sets the name of the object. |
| setNameIsAuto | Sets if the trendline's name is automatically determined. |
| setOrder | Sets the trendline order (an integer is greater than or equal to 2 and less than or equal to 6) when the trendline type is Polynomial. |
| setPeriod | Sets the period for the moving-average trendline. |
| setType | Sets the trendline type. |
