UseAutomaticText: Boolean;
The UseAutomaticText property determines whether automatic text is to be used for a line.
If the property is set to True, text is assigned to a trend line automatically. If the property is set to False, the text is not assigned automatically, and you need to specify the Text property.
The default value of this property is True.
This example assumes that there is the Chart object of the IChart type.
Sub TrendLine;
Var
Chart: IChart;
Begin
Chart.Series.Item(0).TrendLines.Item(0).UseAutomaticText := False;
Chart.Series.Item(0).TrendLines.Item(0).Text := "trendline";
End Sub TrendLine;
After executing the example the chart legend displays the specified text for the trend line.
