Beautiful, Ralf. Do you have any advice on internationalization of a map? It would be nice to hit a button and change the language used, as in a string table in some software.

I'm sorry Monsen. I mistook that link for the PDF. That's exactly what I needed. Thank you!

(You're the best. You, Ralf, Sue, and all the others are truly enjoyable to communicate with.)

I copied orbit radius and period from a NASA page, so yes. The symbol scales are not to scale, because you wouldn't be able to see them if they were realistic!

I present a map generator for my own RPG: Solar Legends

The game uses a solar system map that is updated as the campaign goes on. On one day, the distance between Earth and Mars might be a quick trip, but the next month it could be a long journey. This XP add-on calculates the orbits and draws them out. You can zoom in/out, pick specific planets, and scale everything.

I have the code at:

My next effort will be to package it so that you don't need Visual Studio to run it. I'll probably ask for advice soon. Thanks everybody!

This explains it. It's not a scaling factor alone. It's also that the origin is offset from the graphic. I'm so glad that I'm not crazy, just underinformed.

Thank you!
