Hi, all Could GMT read following format and plot network from points (First -second columns) to points (third-fouth columns)? And the line width is set by the last column. ```auto Latitude Longitude Latitude Longitude Frequency 37.09024 -95.712891 35.86166 104.195397 351 37.09024 -95.712891 46.227638 2.213749 336 37.09024 -95.712891 55.378051 -3.435973 218 37.09024 -95.712891 51.165691 10.451526 150 46.227638 2.213749 55.378051 -3.435973 131 46.227638 2.213749 51.165691 10.451526 121 55.378051 -3.435973 51.165691 10.451526 116 46.227638 2.213749 41.87194 12.56738 113 37.09024 -95.712891 56.130366 -106.346771 110 37.09024 -95.712891 -25.274398 133.775136 107 46.227638 2.213749 40.463667 -3.74922 103 55.378051 -3.435973 41.87194 12.56738 90 37.09024 -95.712891 36.204824 138.252924 83 37.09024 -95.712891 52.132633 5.291266 81 55.378051 -3.435973 -25.274398 133.775136 80 37.09024 -95.712891 41.87194 12.56738 78 ... ``` And the map looks: ![QQ截图20220321083055](https://canada1.discourse-cdn.com/flex047/uploads/gmt/original/2X/9/92fbdb4b1919379d134f4d46f5485025055cb50b.jpeg) ---

yes, but you have to send the data to plot in the format it expects. I would do something like : awk ‘NR\>0{printf("\>-W%.2fp,red\n%s\t%s\n%s\t%s\n",$5/1e2,$1,$2,$3,$4)}’ datafile.dat | gmt plot ---

Here’s a start. Does not not take into account the width in the last column. I thought I could do both line and point within the same loop, but got into problems. ```auto gmt begin lines png gmt set GMT_THEME minimal gmt psbasemap -B -JM15c -R-180/180/-80/80 gmt coast -Ggray # plot lines while read line; do awk '{ printf "%s %s\n%s %s\n", $2,$1,$4,$3}' | gmt plot -W done < data # plot red dots while read line; do awk '{ printf "%s %s\n%s %s\n", $2,$1,$4,$3}' | gmt plot -Sc0.2c -Gred -W done < data gmt end show ``` ![lines](https://canada1.discourse-cdn.com/flex047/uploads/gmt/original/2X/8/8bba48df0737a1c1e283ec09a97d692760c70a9e.png) ---

Might work directly on the file with -S=1p+s I think. We have no mechanism for changing the pen thickness but you could do something like awk ‘{ printf “\> -W%gp\n%s\n”, $5\*0.01, $0}’ | gmt plot -S=1p+s -Vthin … where you would have to figure out a good scale (here 0.01 was used) for scaling your frequency to pen width in points. ---

A question regarding `-R`: It’s not possible to give an `-R` of, say, `-R0/720/-80/80` that would ‘print the world’ two consecutive times, right? Maybe this would be nice for some plots. ```auto $ gmt coast -pdf test -R0/720/-80/80 -W coast [ERROR]: Map region exceeds 360 degrees coast [ERROR]: General map projection error ``` ---

I know, but too hard to change for us. Just do it with two plots. ---

Thanks all ! I can figure out this using other tools (this one is used `Bibliometrix`). But, I am always looking for the possibility to use GMT to do this. Maybe I believe GMT can produce more beautiful maps. ---

Thanks Esteban. I never knew about this, and it is a bit _buried_ in the docs. I see that it applies only to modern mode.
