Bar Graph
Bar graph Bar graphs or bar diagrams are helpful in representing the data visually. In bar graphs or bar diagrams, bars of equal width are drawn horizontally or vertically with equal spacing between them. The length of each bar represents the required information. Therefore, the longer of the bar, greater   value of data. Choosing an appropriate scale for a bar graph is important. Scale means the number used to represent one unit length of a bar. Draw a bar graph 1) In a graph paper, draw two lines horizontal line and vertical line. Both are perpendicular to each other. 2) In the horizontal line mark the information given in the data like years, months, weeks, days, places etc. 3) Pick a suitable scale to determine the heights of the rectangles or bars and then mark the heights on the vertical line. 4) Draw bars or rectangles of equal width and of heights marked in above step on the horizontal axis with equal spacing between them. For example, the scale for the bar graph shown here is 1 unit length = 100 children.
