spline/curve,

add line/spline control point . User created ROI line and points are gray when deselected; control nodes and points are white when selected. Use the point, line or spline tools to create a ROI by clicking to add single points or extend line segmentsand. An enclosed region ROI can be created with the line tool by overlapping the end point with the start point. For data associated with ROI, see Statistics (below).



Line tool -- Enables show spatial plot button which displays values of the selected variable along the line created with two successive clicks of the line tool.



Spline/Curve tool -- Creates a region of interest along the line and enables show spatial plot button. which displays values of the selected variable parametrically by distance along a spline curve defined by two or more successive clicks of the curve tool.
