Cauldron provides ways of downloading data about each report from ‘export and download data’ section in each report accessible from the left bar.
For Cauldron Cloud there is a new option that allows administrators of the platform to export commit numbers for all reports grouped by week with proper empty values for weeks without commits.
This option is available in the reports page. You can create a csv file compressed with all the commits for each report grouped by week.
Once you download that file, you can open it, for example, in a Jupyter Notebook and compare the data between reports.
