  • For each X value, the associated Y values are represented as the length of a bar. Each bar has a fixed width. The bars, however, are stacked on each other so that the second bar segment begins at the end of the first bar. The stack of bars is centered at the associated X value. The X values plot along the vertical axis. To unstack the bars, select Graph: Offset Grouped Data in Layer: None.
  • To display a line when Y=0, select the Bar Graph Show Zero Values check box on the Graph tab of the Options dialog box (Preferences: Options).
