# DensityGraphics

Usage

DensityGraphics[array] 是一个密度图形的表示.

Notes

array 必须是一个实数矩阵，这些实数表示 的值.
• 可以给出下列可选参数:
 "\!\(\*StyleBox[\"\\\"AspectRatio\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"1\\\"\", \"MR\"]\) " 高与宽的比 "\!\(\*StyleBox[\"\\\"Axes\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"False\\\"\", \"MR\"]\) " "是否作出坐标轴" "\!\(\*StyleBox[\"\\\"AxesLabel\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"None\\\"\", \"MR\"]\) " 坐标轴的标签 "\!\(\*StyleBox[\"\\\"AxesOrigin\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"Automatic\\\"\", \"MR\"]\) " 坐标原点的位置 "\!\(\*StyleBox[\"\\\"AxesStyle\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"Automatic\\\"\", \"MR\"]\) " 用来指定坐标轴类型的图形指令 "\!\(\*StyleBox[\"\\\"Background\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"Automatic\\\"\", \"MR\"]\) " 图形的背景色 "\!\(\*StyleBox[\"\\\"ColorFunction\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"Automatic\\\"\", \"MR\"]\) " 用来指定每一个单元颜色的函数 "\!\(\*StyleBox[\"\\\"ColorFunctionScaling\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"True\\\"\", \"MR\"]\) " "在应用一个颜色函数之前是否调整 z 的值" "\!\(\*StyleBox[\"\\\"ColorOutput\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"Automatic\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"DefaultColor\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"Automatic\\\"\", \"MR\"]\) " 输出颜色的类型 "图形元素的缺省颜色" "\!\(\*StyleBox[\"\\\"DisplayFunction\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"\$DisplayFunction\\\"\", \"MR\"]\) " 生成输出函数 "\!\(\*StyleBox[\"\\\"Epilog\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"{}\\\"\", \"MR\"]\) " 主要图形中要使用的图元 "\!\(\*StyleBox[\"\\\"FormatType\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"\$FormatType\\\"\", \"MR\"]\) " 文本的缺省标准类型 "\!\(\*StyleBox[\"\\\"Frame\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"True\\\"\", \"MR\"]\) " 是否围绕图形放上一个框 "\!\(\*StyleBox[\"\\\"FrameLabel\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"None\\\"\", \"MR\"]\) " 框的标签 "\!\(\*StyleBox[\"\\\"FrameStyle\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"Automatic\\\"\", \"MR\"]\) " "给出框风格的图形指令" "\!\(\*StyleBox[\"\\\"FrameTicks\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"Automatic\\\"\", \"MR\"]\) " 框核对记号 "\!\(\*StyleBox[\"\\\"ImageSize\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"Automatic\\\"\", \"MR\"]\) " 将图形载入笔记本的绝对尺寸 "\!\(\*StyleBox[\"\\\"Mesh\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"True\\\"\", \"MR\"]\) " 是否作出网格 "\!\(\*StyleBox[\"\\\"MeshRange\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"Automatic\\\"\", \"MR\"]\) " x 和 y 坐标的范围 "\!\(\*StyleBox[\"\\\"MeshStyle\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"Automatic\\\"\", \"MR\"]\) " 指定网格线风格的图形指令 "\!\(\*StyleBox[\"\\\"PlotLabel\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"None\\\"\", \"MR\"]\) " 图形的标签 "\!\(\*StyleBox[\"\\\"PlotRange\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"Automatic\\\"\", \"MR\"]\) " z 的范围 "\!\(\*StyleBox[\"\\\"PlotRegion\\\"\", \"MR\"]\) " "\!\(\*StyleBox[\"\\\"Automatic\\\"\", \"MR\"]\) " 将被填充的最后显示区域

DensityGraphics能使用Show显示.
DensityGraphicsDensityPlotListDensityPlot生成.
DensityGraphics[g]ContourGraphicsSurfaceGraphics 对象转化为DensityGraphics.生成的图象能通过 Show显示.
Graphics[DensityGraphics[ ... ]]由一个普通Graphics对象生成一种表示.
