I am currently defining new dashboards with charts for additional quality reporting, etc. One of the charts I want to create is (for example) showing the trend of the amount of (field) state the (type) Defects are in for a given project. The project should be selectable in the dashboard-project field and not "hardcoded" in the chart, so that it is useable for each project. The type Defect has 7 possible states.
When I pick the "Trend" chart type, I do not have the option to use a query. When I select "State" as values To Chart and add the 7 states of the Defect type in the "values" field, I will see all the Defects, but I will also see all the other types that happen to share (some of) the states with Defect. (For example, Change Request shares all the same states in our solution)
When I pick the "Item Fields Trend" I can select a query, but I cannot pick a meaningful field, unless I add specific fields to the project type.
My solution so far:
- Create a query for each state in the Defect Type. For example "type = defect AND state = analyzing".
- Add a field (computated using the queries above, store historic values, static) per Defect-state to the project type. For example "Defects in state Analyzing Count".
- Create a chart "Defect State Trend" of type Item Fields Trend. Query "all projects", vertical bar graph, charting values -> add all those Defect-state fields from the project type.
That works.... but it seems like an awefully complex way for just one chart. I need to create 7 queries and 7 fields just for one chart. If I do this for every chart I want, I'll end up with *tons* of fields and queries.
Questions:
1) Is there a better way to achieve what I am trying to get?
2) If not, is it a problem to create so many fields (other than the work involved ofcourse 
), for example on database performance or anything else that I might be unaware of?
