Purpose
The Dashboard provides a consolidated view of your project's health and the most important cards (widgets). Cards are visual summaries of quality and performance indicators — they show totals, counts, and small trend summaries.
Key areas
Cards

Each card on the dashboard has various presentation options
Categories : Represents the cards title
Good / Bad chip : represents if the results are in the good or bad range
Settings : Enables the user configuration of any parameters for the card
42 the number of groups for the underlying ecSQL
156874 the number of elements associated with the 42 groups
38 good groups, those groups which pass the defined rules
63050 the number of elements that are part of the good group
4 bad groups, those groups which fail the defined rules
93824 the number of elements that part of the bad groups
40% the quality score ie 63050/154687 to provide the quality score
Trends : If Trends are enabled, then this will show the trends between user determined saves. If the user does not Save the dashboard score then there will be no trends
: imodelconsole will open the imodelconsole with the underlying query and expanded parameters.
Looks like the Save option is not enabled on Dashboards
Notes
CardDefinition which includes a presentation type and an ECSQL query. The evaluation rules (thresholds or ratio) are part of the card definition and determine the good/warning/bad classification shown on the card.
