@SBattuello if you want all reports to be filtered by a date range, and some are excluded from the dashboard filters, yes, you would have to set them per report.
Regarding your other question, your currently visualizing the count of contacts by ticket create data – is that really what you’re trying to visualize?
In any case, if you don’t want HubSpot to skip weeks, make sure to use a vertical or horizontal chart. HubSpot should then visualize an uninterrupted timeline.
