There are eight presentation features which you can set when generating a report. These options determine the initial display of the pie charts; but, the Pie Chart tool enables you to easily modify individual pie chart displays even after they have been created. First we'll have a look at the initial presentation settings.
Display: The creation of pie charts, particularly those with many slices, can take some time to build and could potentially put strain on the server as it is a resource-intensive process. Furthermore, larger surveys (with many questions) might produce a very long report. Therefore, it is advisable to display only a few questions at a time. Nevertheless, it is ultimately up to you how many pie charts to display at once. The options are as follows:
- All – Display all questions for all sections at once.
- Section – Display each section separately, using links at the bottom of the section report to navigate between sections.
- Question – Display each question separately, using links at the bottom of the question report to navigate between questions.
Accordion: In the event that you choose to display many pies at once, you might find it useful to initially collapse all the sections and questions, thus enabling you to expand only the questions whose reports you particularly want to view.
In the image on the right, notice that only one of the pies is visible. This is because when the report was generated, we decided to show All, however, Accordion was set to Collapsed; once the collapsed report was displayed, we navigated to the Importance answer group pie for the Restaurants question in the section named Paradise's Features. To display or hide any section, question or response pie, simply click on its heading text.
Chart Size: Three predefined pie chart sizes are available to choose from. Small is 300x198 pixels, Medium is 450x300 pixels, and Large is 600x395 pixels. Choose the size that looks best for your screen resolution. Sometimes there are so many slices that when the labels are visible they overlap. In this scenario, one way to resolve the issue may be to enlarge the pie; for even though the pie is enlarged, the label font size remains the same.
Legend: Select whether you want to initially Show or Hide the pie chart's legend. Like most other Presentation options, you can change the display for each pie after the report loads. For example, if you have chosen to display the legend initially and then decide to hide one legend for one of the pie charts after it loads, simply access the pie chart's toolbar by clicking the toolbar icon , and then uncheck the Legend checkbox.
Colors: Choose whether the pie chart slices should use More or Less colors. If you choose More, all of the available colors in the color library will be used for slices before repeating colors. If you choose Less, only the first few colors in the library will be applied to slices. (This setting cannot be modified once report generation takes place.)
Decimals: Select how many decimal places you want to have appear in percent labels. The choices are 0, 1, and 2. Due to rounding, the total percentages for slices may add up to slightly more than 100%; therefore, additional decimal places will help to avoid these minor inaccuracies. (This setting cannot be modified once report generation takes place.)
Min %: Slices representing less than 1% of the pie cannot be represented in their own slice, but rather are combined with other small slices to form a single slice labeled "Other". You can choose to increase the minimum percentage to 2, 3, 5, or 10. Increasing the minimum percentage can help to avoid overlapping slice labels, thus ensuring a cleaner graphic representing the more popular responses. (This setting cannot be modified once report generation takes place.)
Graphic: Pie charts appear as colored slices. You can optionally add the Option Text and/or the slice Percentage to the graphic. Once the pie charts are created, however, it is still possible to remove all labels from any pie, or even remove only labels from certain slices.
Once you have specified all required criteria and selected your initial presentation settings, click Get Report to view the pie charts.
