Each row is a single narrative, each cell is a quarter. The brighter the cell (from red to near-white), the more often the channel spoke about this topic that quarter. Each row is normalized to itself, so even rare topics show their own bright peaks.
On hover you'll see two figures: relative activity — how loudly this topic sounded in the given quarter compared to its own peak (100% = the topic's loudest quarter, 0% = the topic was silent); quarter share — its absolute share of all messages in that quarter.
