Data Regions
overview     see also 

The data region of a graph is where Minitab displays the data. You can place additional text, lines, symbols, and polygons in the data region. A data region uses a coordinate system in placing items relative to the points on the graph. See Region Coordinate Systems.

In most cases, graph windows have a single data region.

When you panel a graph, you choose to display the resulting data regions on the same page.
