Using your very useful DataPlotCls, as i told you i am working on navigational marine charts.
For special application in celestial navigation i have to use what we call " a plotting sheet ", its a part of Mercator chart reusable paper with very big scale around one nautical mile per centimeter.
I would like to know if there is some examples about customizing ticks, degrees, minutes , etc...
I have attached an image in this msg.
Regards,
