Public ReadOnly Property TrendlineLabel() As ChartText

The contents of the Trendline label are generally controlled through the Trendline.ShowEquation and Trendline.ShowRSquaredValue values. However, when using .xlsx files you can override this default text with the ChartText.Text property of the TrendlineLabel object. You can also use this property to manipulate the formatting of the label.
