A Pie chart displays the contribution of fractional parts to a whole and is most commonly used to make comparisons between groups. Show
Pie charts have no axes. When you use a numeric field, the chart can calculate the percentage of each value to the total. The following image displays a Pie chart with a legend: TypesThe Pie chart supports the Doughnut type which has an open space in the center. To control the width of the open space, use the Creating Pie ChartsIn this section, you will create a Pie chart. 1. Add the GraphTo add a new Graph report item to the report, refer to the article getting started with the Graph report item. 2. Set the SeriesGroups HierarchyNow you can set the SeriesGropus hierarchy of the Pie chart:
3. Set the CategoryGroups HierarchyNext, you will have to define the CategoryGroups hierarchy of the Pie chart:
4. Configure the Coordinate SystemHere you will specify the coordinate system details:
5. Configure the SeriesIn this step, you will configure the series of the chart:
6. Style the AppearanceTo set the color palette, format the labels, define the values of the legend, and elaborate on any other styling options, refer to the section on formatting the Graph. Displaying Percentage ValuesPie charts represent proportions of the total. As a result, it is common to format Pie chart labels as percentages. For consistency with other chart types, the Pie chart does not display percentage labels by default. To show Pie chart labels with percentages:
Preventing Overlapped LabelsBy default, the layout engine will try to arrange the data labels so they do not overlap. When the bounds of two or more labels overlap, the engine will move them and their adjacent labels vertically, trying to find them a proper non-overlapping positions. During this rearrangement, a label can be moved aside from its original location, which may produce a hard to read chart. Additionally, if the plot area doesn't provide enough space and there are many data points, the labels will overlap. To prevent the Pie chart labels from overlapping, use any of the following approaches:
For Pie charts with many data points, the best approach is to use a combination of the above-mentioned approaches. The following image shows a Pie chart series that has its
Merging Pie SlicesBased on the data, a Pie chart may produce too many slices, resulting in unreadable data presentation. To overcome this data presentation, you can merge slices that are considered insignificant into a single slice on the Pie chart. To control the merging setup, use the
To turn on the merge logic:
By default, the merged slice is labeled in the legend of the chart as Others. To modify the name, set the
To customize the styling of the merged data point, its label, or the corresponding legend item, use the corresponding Conditional Formatting property by using the Design Considerations
