Read/write Boolean.
|
| Format |
Represents the format of the trend line.
Read/write IFormat.
|
| Forward |
Specifies the number of categories (or units on a scatter chart) that the trendline extends after the

(Inherited from IFormattedTextContainer.) |
| TextFrameForOverriding |
Can contain a rich formatted text. If this property is not null then this
formatted text value overrides auto-generated text.
Auto-generated text is an implicit property of the data label, the display
unit label of the value axis, the axis title, the chart title, the label of the trendline.
Auto-generated text is formatted with the IFormattedTextContainer.TextFormat property.
Read-only ITextFrame.
(Inherited from IOverridableText.) |
| TrendlineName |
Gets or sets name of the trendline.
Read/write String.
|
| TrendlineType |
