You would pass ndtooned(rain_region) into gsn_histogram, and it doesn't matter whether you pass every time step individually or all timesteps at once. </div><div>Adam</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Sep 9, 2019 at 12:38 AM Lyndz via ncl-talk <<a href="mailto:ncl-talk@ucar.edu" target="_blank">ncl-talk@ucar.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div dir="ltr" class="gmail-m_6819846108724961001gmail-m_1187603261618039321gmail-m_-2912153877904815092gmail_signature"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div>Dear NCL-experts,</div><div><br></div><div><b>[Details]</b></div><div><b><br></b></div><div>I am using the aphrodite rainfall data set, which I uploaded in my dropbox folder:</div><div><a href="https://www.dropbox.com/s/lbkjlqgq9era5c7/APHRO_AMJ_1979-2015.nc?dl=0" target="_blank">https://www.dropbox.com/s/lbkjlqgq9era5c7/APHRO_AMJ_1979-2015.nc?dl=0</a><br></div><div><br></div><div><br></div><div>I would like to count the number of grid points over a specified region with rainfall in the following intervals(mm/day): 0-2, 2-4,4-6,6-8,8-10,10-12,12-14,14-16,16-18,18-20,20-22,22-24,24-26,26-28,28-30.
