ColorData

ColorData["scheme"][par]ColorData["scheme",par] 给出指定颜色方案中对应于参数值 parRGBColor 对象.

ColorData["scheme"] 给出一个 ColorDataFunction 对象.

默认情况下,颜色梯度有一个范围从0到1的单一参数.

ColorData["collection"] 给出名称集合中的颜色方案列表.

获得集合的列表:

ColorData[]
{"Gradients", "Indexed", "Named", "Physical"}

求出属于每个集合的方案:

ColorData["Named"]
{"Atoms", "Crayola", "GeologicAges", "HTML", "Legacy", "WebSafe"}

梯度是一个连续颜色函数,它适用于 ColorFunction:

DensityPlot[y + Sin[x^2 + 3 y], {x, -3, 3}, {y, -3, 3}, 
ColorFunction -> ColorData["SunsetColors"]]

索引的方案包含具体值相关的颜色列表:

ColorData[3, "ColorList"]

MapThread level 的区别

In[2]:= MapThread[f, {{{a, b}, {c, d}}, {{u, v}, {s, t}}}]
Out[2]= {f[{a, b}, {u, v}], f[{c, d}, {s, t}]}
In[3]:= MapThread[f, {{{a, b}, {c, d}}, {{u, v}, {s, t}}}, 2]
Out[3]= {{f[a, u], f[b, v]}, {f[c, s], f[d, t]}}

Grid temple

Grid[(*start grid *)
 Prepend[(*start prepend names horizontal*)
  MapThread[Prepend,(*start prepend names vertical *)
   {(*add names column*)
    datalist,(*add the data to display*)
    name`vertical (*end prepend names vertical *)
    }
   ],
  {"", name`horizontal}(*end prepend names horizontal*)
  ]
 , Frame -> {All, All}
 , Spacings -> {2, 2}
 , Background -> {None, {{None, None}}}
 ](*end grid *)

Grid 背景颜色玄学用法

设置指定项的背景:

Grid[Table[x, {4}, {7}], 
 Background -> {None, None, {{1, 1} -> Pink, {3, 4} -> Red}}]

设置网格区域的背景:

Grid[Table[x, {4}, {7}], 
 Background -> {None, None, {{1, 1} -> Pink, {3, 4} -> Red}}]

不显示行号

SetOptions[EvaluationNotebook[], ShowCellLabel -> False];
