GridLines
 Usage
• GridLines是二维图形函数的可选项，用来指定网格线.
Notes
• 可以使用下列GridLines设置:
| "\!\(\*StyleBox[\"\\\"None\\\"\", \"MR\"]\) " | 不画出网格线 | | "\!\(\*StyleBox[\"\\\"Automatic\\\"\", \"MR\"]\) " | "自动放置网格线" | | {"\!\(\*StyleBox[\"\\\"xgrid\\\"\", \"TI\"]\)\!\(\*StyleBox[\"\\\",\\\"\", \"MR\"]\) \!\(\*StyleBox[\"\\\"ygrid\\\"\", \"TI\"]\)"}" " | 分别在每一个方向上指定网格线 |
• 在Automatic设置中,网格线通常被放在坐标具有最小数字(十进制表示)的点上. • 在每个方向上,可以使用下列网格线可选项:
| "\!\(\*StyleBox[\"\\\"None\\\"\", \"MR\"]\) " | 不画出网格线 | | "\!\(\*StyleBox[\"\\\"Automatic\\\"\", \"MR\"]\) " | 自动选择网格线位置 | | {"\!\(\*StyleBox[\"\\\"x\\\"\", \"TI\"]\)"1"\!\(\*StyleBox[\"\\\",\\\"\", \"MR\"]\) ""\!\(\*StyleBox[\"\\\"x\\\"\", \"TI\"]\)"2"\!\(\*StyleBox[\"\\\",\\\"\", \"MR\"]\) ... "}" " | 在指定位置画出网格线 | | {{"\!\(\*StyleBox[\"\\\"x\\\"\", \"TI\"]\)"1"\!\(\*StyleBox[\"\\\",\\\"\", \"MR\"]\) ""\!\(\*StyleBox[\"\\\"style\\\"\", \"TI\"]\)"1}"\!\(\*StyleBox[\"\\\",\\\"\", \"MR\"]\) ... "}" " | "使用指定风格的网格线" | | "\!\(\*StyleBox[\"\\\"func\\\"\", \"TI\"]\) " | 将把一个函数应用到xmin，xmax上以获得网格线可选项 |
• 网格线的风格可以包含诸如RGBColor和Thickness的图形指令. • 网格线的缺省颜色为亮蓝色.
• 网格线函数func[xmin, xmax]可能返回任何其它网格线可选项. • 在使用Automatic设置时,AbsoluteOptions给出GridLines指定的显式形式.
