Aggregation mode

When in aggregation mode, a chart shows the aggregated (composed) values instead of the individual values. This type of display is useful if you want to present summarized results in charts. Following types of aggregation are available: unspecified, average, summation, maximum, and minimum. If the type is not set (unspecified) the average is used. The aggregation mode can be set for at the most 4 dimensions, depending on the chart type.

Setting a chart in aggregation mode

  1. Select the chart, and click  to open the chart's Settings window.

  2. On the Definition tab, click the cross  next to Aggregation mode.

  3. Close the Settings window.

  4. Optional: By default, the aggregation type is not set. In that case the type "Average" is used. If you want to set a different type of aggregation, open the chart dimension window, and under Aggregation, set the desired aggregation type for the available dimension(s).

Count mode

When in count mode, instead of showing for each member of the population what its value is for a certain metric, the chart shows how often each score occurs for that population. For example, scoring the business value of application costs on a scale from 1 to 10, results in a chart showing the business values and for each of these values how often they occur in the portfolio.

The count mode is only available in pie charts and bar charts with an attribute or metric with an enumeration (closed list of values) as dimension.
