Chinese speleothem δ18O (top), age gap (middle strip) and directional window statistic (bottom)

The statistic is computed on −δ18O, so S > 0 = stronger monsoon. Bottom panel: directional mean(≥p95) − mean(≤p05) over a window of length x. Middle strip: distance from each grid point to the nearest raw sample (yr), with its 95th percentile. Everything is computed in this browser — there is no server.
Window length x:
Blue line plo (0-5%):
Red line phi (95-100%):
