Image Plot
Plots of the intensity profile through an image, averaged over
specified rows or columns
can be extracted from an image table by specifying the
following information:
Plot Rows or Plot Columns 
Select whether you want to plot row or column data from the
   table.  The line plot will be the image data versus the row/column
   index.
Row/Column Range To Plot
List the row/column index to plot or, to plot an average of
   multiple rows/columns, list the index range in the form of
   "start-end".
Add curve
Indicate whether the resulting curve should be plotted in the
   currently selected graph in POW.  If unset (the default), a new
   graph will be created.
Note that the interactive 'Draw Profile" tool in POW can be used to display
the intensity profile along a line drawn at any angle through the image
