All-in-One Event Calendar (ai1ec) registers ai1ec_event as a custom post type and stores start, end, venue, category, and recurrence rule in postmeta. The data is clean enough to drive a full reporting layer, but the admin never tries to be one: it ships a posts list, leaving organizers to scroll the front-end calendar to answer planning questions.

SleekView Charts reads the same ai1ec event CPT and turns it into a configurable dashboard. Number cards show the headline counts: total upcoming events, events this month, cancelled this quarter. Pie cards summarize category mix and status distribution. Bar charts rank venues by load. Area and line charts trace event volume across the next twelve weeks, so the team can see the gaps and clusters before the calendar fills.

Each card reads through the same meta keys ai1ec writes from the editor, so the front-end month, week, and agenda views continue to render normally. The dashboard is an admin companion, not a replacement, and it gives the team a single screen that answers the questions a posts list cannot.

All-in-One Event Calendar earned its reputation by getting the data model right: events as a custom post type, iCalendar-aligned meta, recurrence rules in a structure other tools can consume. That cleanliness is exactly why the absence of a reporting surface is felt so acutely. Organizers do not browse a calendar to answer how many events are scheduled this month, which venues carry most of the load, or what share of the schedule is still in draft.

They want a screen that aggregates the data they already have into shapes they can read in seconds. SleekView Charts reads the existing ai1ec meta, applies a chart-card layout over it, and turns the admin from a content editor into the planning dashboard the plugin always implied. The front-end calendar continues to render the same data because every card is a read against the same meta the public views consume, with the only difference being that the team finally has one screen that answers the planning questions instead of four browser tabs that hint at them.
