I have calculated spatial slope and p_value using scipy.stats.linregress looping over individual pixels (lat*lon) along the time dimension. Now I can make spatial plot of slope value using plt.pcolormesh (lat, lon, slope). But over it I want to add p_value<0.05 as dot mark wherever applicable to the same slope spatial plot. Similar to the below images. Any help or remark regarding the same from the community............ Thanks

  • Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking. – Community Nov 19 '21 at 09:12
  • I want to ask about how to add significance (p<0.05) as dot/point over the same trend spatial map. – HARSHBARDHAN KUMAR Nov 21 '21 at 10:05

ax.pcolor(lon, lat, hatch, hatch='..', zorder=1, alpha=0.0, transform=ccrs.PlateCarree()) this worked for me!

Similar to Hatch area using pcolormesh in Basemap
