Bar graphs comprise an axis and a series of labeled horizontal or vertical bars that show different values for each bar. The numbers along a side of the bar graph are called the scale. Line Graphs are used to show how two parameters are related to each other. Or to put it another how one variable changes as another changes. A Line graph consists of two axis, a vertical or Y axis and a horizontal or X axis. Pie charts (or sometimes called circle charts) provide a visual representation of data as slices of a pie. The greater the data value the larger the pie slice. The sizes of each slice are calculated such that the total sum of all the data elements will represent the full 360 degree pie circle. |
