Maximum, average, percentile, or median of values from the field. If a field is used, the values can be calculated as a sum, minimum, The values in the chord diagram can be symbolized as a count of features in the categories or as a number or rate/ratio field. The length of each arc and the thickness of each chord are determined by its The chords are the links or connections between the arcs in the circle that show the relationships or flow between the two categories. The categories are arranged in a circle as arcs. The result dataset can be used to create additional visualizations, rename the fields on the chart axes or in the pop-ups, or apply filters to the chart. This chart type creates a result dataset in the data pane, which includes the fields used to create the chart. For the Visualization type menu, only compatible visualizations (including maps, charts, or tables) will be displayed.Ĭhord diagrams can also be created using View Chord Diagram, which is accessed from the Action button under Find answersand How is it related? Usage notesĬhord diagrams are styled by unique values. For the Chart menu, only charts that are compatible with your data selection will be enabled. You can also create charts using the Chart menu above the data pane or the Visualization type button on an existing card. To create a chord diagram, complete the following steps: For example, more people migrated from Alaska toĬalifornia than vice versa. In the ratio layout, each chord represents the bidirectional flow between two states, so tapered chords indicate more volume of flow in one direction than the reverse. The chords show the directed flow between states. ![]() The arc length for each state represents the flow (migration) into the state, so you can see which states recorded the Nevada, Oregon, Utah, and Washington) are displayed as different colored arcs around the circle. ![]() The states (Alaska, Arizona, California, Idaho, A chord diagram can be used to determine the migration State-to-state migration flows among eight states on the West Coast of the United States in a particular year. Relationship or volume of the flow between the categories.Ī census bureau department is studying the Is bidirectional, with its thickness and value determined by the extent of the When the values in the two category fields are Miami recorded the largest sum of TIV inĮach policy class, while cities such as Saint PetersburgĪnd Jacksonville have policies in three out of the four policy classes. ![]() You can see not only which city or policy class recorded the highestĪnd lowest values, but also the policy classes that contribute to the sum of TIV for each city. The length of the arc and thickness of the chords are determined by the sum of the TIV. The Policy_Class values (Property, Life, Disability, andĪutomobile) and City values (Miami, Jacksonville, Orlando, Saint Petersburg, and Tampa) are displayed as different coloredĪrcs around the circle. The chord diagram above provides a sum of the TIV for each category of insurance policy acrossĬities. ![]() A chord diagram can be used to visualize the distribution of subgroups for each category. One step in the review is to compare the total insured value (TIV) of policies in each policy class across cities.
