*   Stat Polygon v1.0 by mjshi
*   Free for both commercial and non-commercial use, with credit.
* ------------------------------------------------------------------------------
*                                 Valid Stats
* ------------------------------------------------------------------------------
*         These will be drawn counterclockwise, starting from the top.
*
*                0 = MaxHP    2 = ATK    4 = MAT    6 = AGI
*                1 = MaxMP    3 = DEF    5 = MDF    7 = LUK
*
* ------------------------------------------------------------------------------
*           ** This plugin IS compatible with Yanfly Status Core! **
*                    Place it below the Status Core plugin.
* ------------------------------------------------------------------------------
*   You just need to change the Center X, Center Y, and Make Way! values a bit.
*   Just so you can see the graph, I recommend setting both the centers to 100,
*   and Make Way! to at LEAST 200. You'll need to make additional adjustments
*   from there.
