Bar graph
The “normal” bar graph, with a zero at the left end, is a graphical representation of a reading as a portion of a range. (See Figure
3-3.) The vertical lines displayed along the bar designate 0%, 25%, 50%, 75%, and 100% of full scale. Each full segment of the
bar represents approximately 4% of the range limit.
