The record is for lightning flashes in the continental U.S. and surrounding waters within the latitudinal band between 258 and 458N.
I want to display the result in x-y co-ordinate plot. However, the data is very large such that when plotted, everything just appeared blurred. Is there a way of using color codes to indicate the regions of higher or lower flash densities? I can attach the plot I generated but I am not sure if the moderator will allow it to go with this. I will send it in a separate email if required. Thank you so much for sparing your time.
