Webcast Charts

Webcast Charts shows you a number of "suburst charts" for various metrics.

• Choose AAS, TLH, SS, or CUME.
• A Sunburst chart appears for each of the following dimensions:
  • Top 20 stations *
  • Country and Region ^†
  • Family and Device
  • DMA
  • Distributor
  • Radio Format *

* Only displayed when filtering by publisher or group.
^† Region refers to the subdivisions of a country, such as state in the U.S., province in Canada, and administrative region in France.

Adding Filters

You must include at least one publisher/group/station, a Date Range, and a Daypart selection.

• Click the first filter button to open the Selection Management Area to select the publisher/group/station. You can select multiple items of the same type, such as multiple groups from the same publisher, or multiple stations within the same group. You cannot intermix, such a choosing stations from different publishers or stations from different groups.
• Click the current date range selection to open the Selection Management Area to change the date range.
• The default daypart selection is Daypart - All Times; to select a specific daypart, click the selected daypart and choose a daypart from the list that appears in the Selection Management Area.
• Click Add new to add one or more additional filters. If you add no additional filters, the charts displayed are for all dimensions for the selected publisher, group, or station and date range. Otherwise, the charts show only the filtered data. The filters are the same as are found in Webcast Explore, and are a subset of the Webcast Explore Dimensions list.

Selecting the Metric

To change the metric, click the current metric to open the metric picker. Select the metric you want to display and click Apply (or Apply and Run).

Reading Sunburst Charts

Sunburst charts are interactive diagrams that change as you move your cursor over various parts of the chart. Charts uses both single-tiered sunbursts and two-tiered sunbursts.

Single-tiered Sunbursts

Single-tier sunburst charts are simple to use because they are only one level deep. Look at the DMA sunburst chart: the ring is composed of color-coded segments, each representing a DMA region. (Only the top ten regions are listed; the rest are grouped under "other.")

In the example below, the data for "New York" is revealed (the dark green segment). When you hover your cursor over the New York segment, its data appears in the center of the graph.

Two-tiered Sunbursts

The Device and Family item is an example of a two-tiered sunburst graph. At the top level, the outer ring shows a segment for all devices, color-coded to match their device family in the inner ring. If you select a device you see its data in relation to all devices in the graph.

You can then drill down to the second level by selecting a device family at the top level. Now the graph shifts to only show you devices from that device family, and the data presented for each device is in relation to its device family.

For example, if you select the segment for "iPhone" in the outer ring at the top level, you will see the data for iPhones relative to all devices in the chart. Now click on the device family segment ("Mobile," from the inner ring) to drill down to the mobile device family level. The chart re-draws to only show devices from within the device family ("Mobile"). The outer ring still shows the specific devices, but now it only shows mobile devices. It shows you the same metrics values for as at the top level, but the percentage is now the percentage of mobile instead of the percentage of all devices.

"Unknown" and "Unspecified" Items

You might occasionally see data in your sunburst charts reported as "Unknown," "Unspecified," or simply blank. Typically, this means the data being analyzed does not contain the information needed to be more specific.

For example, if your DMA or DIST charts report an item with a percentage value but no label (e.g., simply "4%" instead of "Chicago 4%") it means that 4% of the reporting data does not contain DMA or DIST information. For DMA, this typically means traffic from outside of the USA. For DIST it typically refers to data from sessions that did not include distributor targeting (the dist query parameter).

In the case of Device and Device Family sunburst charts, "Unknown" and "Unspecified" have the following meanings:

• "Unspecified" refers to data where the device or family wasn't specified in the user agent, so it could not be categorized.
• "Unknown" refers to data for user agents that we do not yet categorize. You should see very little of this, so if your "unknowns" represents a significant amount of traffic being reported, please contact Triton Digital support so we can analyze the data and hopefully categorize those user agents.
