<div dir="ltr"><div><div>Dear NCL user,<br><br></div>I have plotted the lag correlation between 2 variables. I also want to highlight those parts which are significance at 95 % with black lines, over the attached plot (or as an overlay plot). So it can easily be vizulise that which part of the given region is more significant with black lines or dot points.<br></div><div><br>please provide some suggestion on that.<br></div><div><br></div>I have data of one month with 31 days for each variables.
