<div dir="auto">Sir,<div dir="auto"><br></div><div dir="auto">The time interval for WRF file is 3 hour and there are 25 time steps. The first time steps is 22/09/2018 1200. The time should start from 22/09/2018 and end at 25/09/2018 with 25 time steps (22/09/2018 1200, 22/09/2018 1500 etc upto 25/09/2018 1200). But the graph ends at 23/09/2018 1200 which correspond to 25 time steps at 1 hour interval. I want graph to end at 25/09/2018 1200. I hope I am able to clarify my doubt.
