Explanation
A forecast in Power BI extends a line chart beyond the existing data range to project future values, typically displayed with a shaded confidence interval band. This is what distinguishes the Modified exhibit from the Original: the Modified version shows projected future data points. A trendline (B) overlays a statistical line on existing data but does not project into the future. A measure (A) adds a data field, not a visual predictive element. An Average line (D) draws a flat horizontal reference line.
