Line Profile Plot changes segmented line to spline fit

Cammer, Michael
When using Line Profile Plot with the line width set wider than 1 pixel, the line is redrawn as spline fit.  Is this what is supposed to happen?  I didn't see an option for this.
Thanks,
Michael

ImageJ creates profile plots of a line selections wider than one pixel by straightening the lines using the equivalent of the Edit>Selection>Straighten command. Straightening of non-straight lines requires a spline fit. There is no option to disable the spline fitting.
