WebinarPress runs webinars as a WordPress custom post type with registrant records, attendance flags, and traffic source captured alongside each event. The default admin handles single-webinar triage well: each webinar has its own registrants screen, its own attendance toggle, its own follow-up tagging. A monthly demo plus a launch series plus a customer-onboarding cadence quickly becomes ten or more webinar screens to reconcile by hand.

The cross-event view is exactly where the marketing question lives. How many registrants converted to attendees this quarter? Which traffic source drove the highest attendance rate? How is the webinar pipeline shaping up against the same period last year? Each of those questions exists as a query on the WebinarPress data, but the default admin asks the team to assemble the answer one webinar at a time.

SleekView Charts reads the WebinarPress webinar CPT and registrant data directly. A Number card anchors total registrants this month. A Donut splits attendance into attended, no-show, and replay-watched. A Horizontal Bar ranks traffic sources by registrant count. An Area trends registrations over time. Same data, organised as the dashboard the team opens at the start of a planning shift.

Webinars are a series, not a one-off, and the value of the registrant data sits in the cross-event view. A single launch can run for months across a kickoff, a mid-series replay, and a closing demo, with traffic from paid ads, organic search, partner shoutouts, and customer referrals. WebinarPress captures each of those signals correctly, but the default admin scopes them per webinar, which means the conversion question ("how is this series performing against last quarter") gets answered with a spreadsheet, not a screen.

Treating the webinar CPT as a relational dataset and rendering it as four chart cards turns the per-event report into the pipeline view marketing and sales actually need. Decisions about which channel to scale, which webinar topic resonates, which replay segment converts, get grounded in a chart that updates the moment a registration comes in.
