Hello,
I discovered OpenGribs and your new iniciative XyGrib only a few days ago. It has been a nice surprise. Thank you very much!
As I have been doing with zyGrib, I'll try to colaborate with XyGrib according to my possibilities, In particular with the Spanish translation. And also suggesting some improvements to the program. The first one is the possibility of modifiying line width and colour for geopotential isolines. That would allow to plot very usefull weather charts, specially to study or teach meteorology.
By the way, I am not sure that this is the correct place for this message. If not, please let me know.
Regards,
Tropelio
