Origin Placement

The easiest way to customize an origin is by controlling its placement, using the Axes OriginPlacement property. When set to Auto, the origin is placed at the axis minimum or at zero, if the data contains positive and negative values or is a bar chart. You can also explicitly place an origin at zero, the axis minimum, or the axis maximum. OriginPlacement is located on the Annotation Tab (Axes) on the Property Pages.
