PolarAxesOrigin
扇形グラフと極プロットのオプションで,どこに極軸を引くべきかを指定する.
詳細
- PolarAxesOrigin->{θ,r}は放射軸が角
で置かれ,角軸が半径 r で置かれるように指定する. - 角
はラジアンで正の
軸から反時計回りに測られる. - PolarAxesOrigin->{{pos,dir},r}は放射軸が位置 pos に置かれ,dir の方向を向くように指定する.
- pos が取り得る値はLeft,Right,Top,Bottomである.dir が取り得る値はUp,Down,Left,Rightである.
- Automaticの設定では,原点が自動的に選ばれる.
