I think you are referring to the bars in the technical charts. You must be aware that a bar graph is a chart that plots data using rectangular bars or columns (called bins) that represent the total amount of observations in the data for that category. Bar charts can be displayed with vertical columns, horizontal bars, comparative bars (multiple bars to show a comparison between values), or stacked bars (bars contain multiple types of information).

The purpose of a bar graph is to convey relational information in a jiffy as bars display the quantity for a particular category. The vertical axis of the bar graph is called the y-axis, while the bottom of a bar graph is called the x-axis. When interpreting bar graphs, length of the bars/columns determines the value as described on the y-axis. The x-axis can be any variable, such as time, category etc. Bar graphs are ideal for comparing two or more values or values over time. Data is displayed either horizontally or vertically. Single bar graphs are used to convey discrete values of an item within a category.
