Apologies if this has been covered elsewhere, but I'm trying to generate a bunch of frames (to animate later with ffmpeg) using QGIS Atlas + NASA FIRMS data. I'm using the date column from the FIRMS data, in YYYY-MM-DD format. QGIS version is 3.10.1
Using this technique from this other post to show cumulative points.
And here are my Atlas settings before I export them as pngs.
Unfortunately this exports a separate png for each features from of the data, rather than grouping all the points under a given date and exporting a single image for that date.
What could I try to export all the points for each date?
