It is a way of calling the bar graph, a representation of values graphed with bars or rectangles distributed over coordinate lines that resemble poles in a network or wire fence. That is precisely why the Greek word 953 was used for the name; 963; 964; 959; 962; ( histós "woven, post holding a woven fence") along with 947; 961; 945; 956; 956; 945; ( gramma "letter, written" ) .
