The 3 Point Segment graph is created from the LINESYMB.OTP template (installed to the Origin program folder).


The line connection display alternates between a straight line for three data points, then no line to the next data point, a straight line for three data points, etc. (the connection type is set to 3 Point Segment on the Line tab of the Plot Details dialog box (Format: Plot)). Thus, every three consecutive data points are connected by two lines (the first, second, and third data points; the fourth, fifth, and sixth data points; etc.). The data points are displayed as symbols.
