This is work in progress
! There are a lot of things that can be improved. This sort-of mimics the functionality of the in-game INCURSION MAP and COSMPIERCER MAP. That is, it will display zones with market orders in the STARCHART format. MARKET ORDER LIST will populate the map with which zones have orders. MARKET MAP will then display the starchart, with the zones of interest having a red background. Here's an example of the zones with elessium orders:
You can keep checking MARKET MAP to pull up the map again without having to repopulate it via MARKET ORDER LIST (until you reset it, at least). MARKET MAP RESET will then clear the zone highlights. Download (version 1.1)
Note: There's something funky going on with the clicky stuff, unfortunately. I'll try to find a fix for that as soon as possible. Don't trust it yet!
