A full view of the dashboard yields a mortality breakdown of over forty different demographic segments in a single view. This, combined with the use of distinct common colors representing specific mortality causes across the individual pie charts enables a health researcher to notice similarities and differences in health and safety outcomes among these distinct segments of the population. With a quick glance, researchers can easily notice what ends the lives of people of different racial demographics, whether certain afflictions kill people of certain races sooner, and whether certain racial demographics seem better protected from certain mortality causes.
For health researchers, this can have applications in research for racial equity, create further questions as to the lifestyles and health decisions of different groups, and point towards investigations into possible genetic proclivities for different diseases in different racial groups. For healthcare providers, understanding an individuals proportionate risks of different ailments can help steer care, giving clues to guide diagnoses, helping to weigh the risks and benefits of different interventions, and also help provide individuals with lifestyle reccomendations best suited to their segments mortality risks.
How to Make a Trellis Chart in InetSoft
To create a Trellis chart in pie chart style like the example described above, follow the basic steps below.
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, including a date column, 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.)
Open a Chart for Editing
If necessary, create a new Dashboard. For information on how to create a new Dashboard, see Create a New Dashboard.
From the Toolbox panel, drag a Chart component into the Dashboard.
Resize the Chart as desired by dragging the handles.
Press the 'Edit button in the center of the Chart or press the Edit' button in the top-right corner.
This opens the Visualization Recommender. Bypass the Recommender by pressing the 'Full Editor' button at the top right to open the Chart Editor.
In the Chart Editor, drag a measure field from the Data Source panel to the 'Y' region.
In the Chart Editor, drag a dimension field from the Data Source panel to the 'Color' region.
Press the 'Edit Color' button to choose the colors. See Group Data by Dimension for more information about the color panel.
Press the 'Select Chart Style button, and choose your desired style. In this example, we will be selecting 'Pie" . This converts the chart into a pie-chart representation.
If you would like the pie slices labelled with text, then drag the same dimension that used in the 'Color' region to the 'Text' region as well.
Optional: Remove the legend if desired. To do this, right-click on the legend, and select 'Hide Legend' from the context menu.
Optional: To place a small gap between the pie slices, right-click the plot area and select 'Properties' from the context menu.
In the Advanced tab of the 'Chart Properties' panel, select Explode Pie' and press 'OK'.
The first pie chart is now complete
To turn the one chart into a Trellis chart, simply add dimensions into the 'X' and 'Y' regions to create the desired arrangement.
