| Rank and spend data are also graphically shown in a pie chart and line graph. |
| The first point on the line graph should line up with the top of the first bar. |
| Do this by looking for a clear breakpoint in the line graph, where it starts to level off quickly. |
| The advantage of using a bar chart over a straight line graph is that it shows the high, low, open and close for each particular day. |
| The line graph shows the cumulative percentage of observations from left to right. |
| If you are making a group bar or line graph, be sure to use different colours for each data set. |
