radius -- 极坐标格半径. 可以为任何正数. 默认为 10.<br />
|
||
|
|
sectors -- The number of sectors the grid will be divided into. This can be any positive integer. Default is 16.<br />
|
||
|
|
rings -- The number of rings. This can be any positive integer. Default is 8.<br />
|
||
|
|
divisions -- 圆圈细分段数. 可以为任何大于或等于3的正整数. 默认为 64.<br />
|
||
|
|
color1 -- 极坐标格使用的第一个颜色. 值可以为 [page:Color] 类型, 16进制 和 CSS 颜色名. 默认为 0x444444 <br />
|
||
|
|
color2 -- 极坐标格使用的第二个颜色. 值可以为 [page:Color] 类型, 16进制 和 CSS 颜色名. 默认为 0x888888
