Trends dashboards provide analytics of project performance, ecosystem and data source related metrics, such as how many total contributors are contributing to your project, number of commits, total number of code backlogs, issues, and many more for a project. These performance-related data are grouped into different blocks of metrics.
You can filter data by time range. For details about filtering data, see Filter Data.
Note: If you filter data by time range on Trends dashboard for a sub project of a project group, then the selected Trends time range will also reflect on the other sub projects of the project group.
Global Trends dashboards provide high level analytics of project performance for all the projects onboarded to Insights. **** The performance-related data are grouped into different blocks of metrics.

Project Trends dashboards provide analytics of project performance data, such as how many contributors are contributing to your project, total number of code backlogs, issues, and many more for the project. These performance-related data are grouped into different blocks of metrics.
Based on the project's configured data sources, following key project performance indicators are displayed at the top:
Total number of unique commits
Number of repositories being monitored
Total number of lines of code added and modified
Total number of Pull Requests / Changesets submitted
Total number of builds being monitored
Total number of emails sent
Total number of relevant mentions on social media channels
Total number of issues submitted
Total number of messages sent in different chat platforms of the project

Click the icons for each metric to view details about the metrics. No Data is displayed for a metric if the relevant data source is not configured for the project.
Navigate to another project of the project group by selecting a project from View Sub Projects drop-down list under the project group name on the top right corner of the overview card.
Contributor Strength: Shows graphs that display total number of contributors on a periodic basis during the selected time range, and represents a periodic growth in the aggregated count of unique contributors analyzed during the selected time range.
The grey colored rectangular card shows the following data in each slide:
The increment number in percentage
Monthly average contributor strength, and
The exact time period during which the numbers increased the most.

For different time periods, different strategies are used to collect, aggregate, and visualize Trends data. Depending upon the selected time period, the data are displayed with different numbers of break points, also called buckets. Following are the different time periods, of Trends dashboard, and the strategies used to aggregate data for each of the time period:
This shows aggregated data for the last 3 months from the current date. The data are aggregated based on a specific interval in days of a month, and are displayed with 12 breakpoints (also called buckets).
This shows aggregated data for last the 6 months from the current date. The data are aggregated based on a specific interval in days of a month, like it is for 3 months, and are displayed with 12 breakpoints.
This shows aggregated data for last one year from the current date. The data are aggregated monthly, and are displayed with 12 breakpoints.
This shows aggregated data for the last two years from the current date. The data are aggregated quarterly, and are displayed with 8 breakpoints.
This shows aggregated data for the last three years from the current date. The data are aggregated every 4th month, and are displayed with 9 breakpoints.
This shows aggregated data for the last five years from the current date. The data are aggregated half-yearly (every 6th month), and are displayed with 10 breakpoints.
This shows aggregated data for last the ten years from the current date. The data are aggregated on a yearly basis, and are displayed with 10 breakpoints.
This shows aggregated data from the year 2000 till the current year and date. The data are aggregated yearly, but are displayed with numbers of breakpoints based on the current year. For example, if the current year is 2021, the break points will start from 2000 to 2021, showing 20 breakpoints.
