Nothing was filed on this symbol inside the window
The window is the last fourteen days, asked of one search by name. Nothing inside it mentioned this symbol, which is a reading rather than a gap. Nothing outside it was searched.
No publisher filed on this symbol here
A publisher appears once it has filed an item inside the window. The window held none.
No day carries an item
A day appears here once at least one item has been read for it. Nothing came back for this symbol, so there is no day to draw.
Every day of the window is drawn, including the ones with nothing on them: a day nobody wrote about this asset is a reading. Days are UTC, and the bars are scaled to the busiest day drawn rather than to a fixed number.
