Scheduled Snapshots of Databoard(s) can be exported as JPG or PDF file formats. If you choose the JPG file format option, the Databoard will be sent as a separate JPG attachment in the scheduled email. If you choose the PDF file format option, the Databoard(s) will be combined in a multipage PDF that will be attached to the scheduled email. Learn more here.
Reports can be exported as PDFs. You can share the reports in multiple ways from the Reports Editor, including downloading the PDF, sending the PDF to specified email addresses, or automating the export. Learn more about how to share the Reports here.
