How to Make a Sunburst Chart in InetSoft
To create a Sunburst chart, follow the basic steps below.
Place the desired hierarchical dimensions in the 'T' region in the Chart Editor, and place the desired measure in the 'Size' region of the Chart Editor. Use the 'Color' region to distinguish particular dimension values by color. NOTE: To create a grid of charts, place dimensions into the 'X' and/or 'Y' regions as well. (See Trellis Chart (Grid) for more information.)
Prepare Your Data
The data source for the chart (data block, query, or data model) should represent dimensions and measures as independent columns or fields, as shown below. See Prepare Your Data for information on how to manipulate your data, if it is not currently in this form. (Note: A properly designed data model will already have the correct structure.)
In some cases (e.g., Pie Chart), you may want your data to provide just a single measure. In other cases (e.g., Line Chart), you may want the data to supply multiple measures. If the data does not provide the correct number of measures, you may be able to alter the number of measures to suit the needs of the chart by "pivoting" or "unpivoting" the data. See Convert Multiple Measures in Prepare Your Data for more information about this procedure.
This example illustrates how to create a Sunburst chart that displays total broken down by state, city, and product name. The example uses the 'Sales Explore' Data Worksheet, which can be found in the 'Examples' folder under 'Data Worksheet'.
Create a new Dashboard based on the 'Sales Explore' Data Worksheet. For information on how to create a new Dashboard, see Create a New Dashboard.
Drag a Chart component from the Toolbox tree to the Dashboard, and press the 'Edit' button at the top-right corner of the Chart to open the Wizard. Press the 'Full Editor' button at the top right to open the Chart Editor. (For more details on creating a chart, see Basic Charting Steps.)
In the Chart Editor, press the 'Select Chart Style' button and choose the 'Sunburst' option. Press the Apply' button .
Drag the 'State', 'City', and 'Name' fields from the Data Source panel to the 'T' region. (NOTE: These fields can be found in the 'Sales Explore' Data Worksheet.)
Drag the 'Total' measure from the Data Source panel to the 'Size region.
Drag the 'State' dimension from the Data Source panel to the 'Color' region.
Optional: Press the Edit Color button next to the 'State dimension, and choose the desired colors to represent the state values. Press the 'Close' button.
Optional: You can add additional dimensions to the Chart if desired. See Trellis Chart (Grid) for information about adding multiple dimensions to a chart axis.
Press the 'Finish' button to close the Editor.
Resize the chart as desired.
Hover the mouse over the chart to see a tooltip providing full information about each group.
You can proceed to edit the titles, legend, etc. See Basic Charting Steps and Chart Properties for more information. See Format Data for information on how to format text on a Chart.
Tool to Make Sunburst Charts Online for Free
To easily and quickly create Sunburst Charts online for free, create a Free Individual Account on the InetSoft website. You will then be able to upload a spreadsheet data set.
Once you have done that, you will be able to proceed past the Visualization Recommender, which can usually get you started creating a dashboard. Since the Recommender does not offer the Sunburst Chart as a suggestion, press the Full Editor button.
Then proceed to build the Chart as described in the previous section.
