                        <span style="font-size:16px;">Have you ever encountered the problem that when you are trying to plot a map, and there is a gap line appears in the figures (figure is attached here)? I think it is because that the beginning and the ending longitudes of the data are different. I have searched through the web and so far no luck. Could anyone provide any insights regarding solving this problem? </span>
