Click on the Chart Wizard icon to begin the four step process of
creating a chart. In Step 1 you will choose a chart type. The nature of
the information on your spreadsheet and level of detail should affect your
choice of a chart type.
A pie chart is best for displaying the breakdown of a single
variable among multiple populations (e.g., campus interlibrary loan users
according to their institutional status) or multiple variables for a single
population (e.g., faculty use of individual electronic resources). A pie chart
graphically demonstrates percentages very well.
Bar or column charts are a good choice for showing comparisons among a
limited number of populations for different variables (e.g., use of a number
of library services by different groups of students).
Line charts do a good job of showing trends over time for one or more
populations or variables (e.g., library gate counts for total population of
users during a single year or for a number of years compared).
