Dashed
是一个图形指令，指明随后的线段应当以虚线画出.
范例
打开所有单元 关闭所有单元基本范例 (3)
Graphics[{Dashed, Line[{{0, 0}, {2, 1}}]}]Graphics3D[{Dashed, Line[{{0, 0, 0}, {2, 1, 1}}]}]Grid[Table[x, {4}, {7}], Frame -> All, FrameStyle -> Dashed]Plot[Sin[x], {x, 0, 2Pi}, PlotStyle -> Dashed]范围 (1)
利用 EdgeForm 画虚线边线：
Graphics[{Pink, EdgeForm[Dashed], Rectangle[]}]Graphics3D[{EdgeForm[Dashed], Cuboid[]}, Boxed -> False]属性和关系 (3)
Dashed 等同于 Dashing[{Small, Small}]：
DashedDashing 和 AbsoluteDashing 提供丰富的方式指明虚线：
Table[Graphics[{Dashing[{r, 0.1 - r}], Line[{{0, 0}, {2, 1}}]}], {r, {0.01, 0.03, 0.05, 0.08}}]Table[Graphics[{AbsoluteDashing[{d, 15 - d}], Line[{{0, 0}, {2, 1}}]}], {d, {2, 5, 8, 12}}]Dashed 是绝对的虚线，与图形大小无关：
Table[Graphics[{Dashed, Line[{{0, 0}, {2, 1}}]}, ImageSize -> s], {s, {50, 70, 100}}]相关指南
