PolarAxesOrigin

是扇形图表或极坐标图的一个选项，指定绘制极轴的位置.

更多信息

  • PolarAxesOrigin->{θ,r} 指定径向轴以角度 theta 放置，角轴以半径 r 放置.
  • 角度 theta 按弧度测量，从 正轴逆时针旋转.
  • PolarAxesOrigin->{{pos,dir},r} 指定径向轴放在位置 pos、方向 dir 上.
  • pos 的可能值有 Left、Right、Top、Bottom. dir 的可能值有 Up、Down、Left、Right.
  • 设置 Automatic 自动选择轴原点.

基本范例  (2)

自动确定极轴原点：

Wolfram Language code: PolarPlot[{1, 1 + 1 / 10 Sin[10 t]}, {t, 0, 2 Pi}, PolarAxes -> True, PolarTicks -> {"Degrees", Automatic}, PolarAxesOrigin -> Automatic]
Wolfram Language code: SectorChart[RandomReal[1, {20, 2}], PolarAxes -> True, PolarAxesOrigin -> Automatic, ChartStyle -> Opacity[0.7]]

指定极轴原点在 且 处：

Wolfram Language code: SectorChart[RandomReal[1, {20, 2}], PolarAxes -> True, PolarAxesOrigin -> {Pi, 1}, ChartStyle -> Opacity[0.7]]
Wolfram Language code: PolarPlot[Floor[θ], {θ, 0, 2Pi}, PolarAxes -> True, PolarTicks -> {"Degrees", Automatic}, PolarAxesOrigin -> {Pi / 6, 8}]

范围  (4)

自动确定角轴和径向轴的交叉点：

Wolfram Language code: SectorChart[{{2, 1}, {2, 3}, {3, 4}, {4, 2}}, PolarAxes -> True, PolarAxesOrigin -> Automatic]

指定角轴和径向轴在 相交：

Wolfram Language code: SectorChart[{{2, 1}, {2, 3}, {3, 4}, {4, 2}}, PolarAxes -> True, PolarAxesOrigin -> {Pi / 6, 5}, ChartStyle -> Opacity[0.7]]

将径向轴放在扇形图表的右边：

Wolfram Language code: data = {Range[100] / 4, Sqrt[Range[100]], Log[Range[100]]};
Wolfram Language code: Table[ListPolarPlot[data, Joined -> True, PolarAxes -> True, PolarAxesOrigin -> {p, Automatic}, PolarTicks -> {None, Automatic}, PlotLabel -> p], {p, {{Right, Up}, {Right, Down}}}]

将径向轴放在扇形图表的左边：

Wolfram Language code: Table[ListPolarPlot[data, Joined -> True, PolarAxes -> True, PolarAxesOrigin -> {p, Automatic}, PolarTicks -> {None, Automatic}, PlotLabel -> p], {p, {{Left, Up}, {Left, Down}}}]

将径向轴放在扇形图表的顶部：

Wolfram Language code: Table[ListPolarPlot[data, Joined -> True, PolarAxes -> True, PolarAxesOrigin -> {p, Automatic}, PolarTicks -> {None, Automatic}, PlotLabel -> p], {p, {{Top, Left}, {Top, Right}}}]

将径向轴放在扇形图表的底部：

Wolfram Language code: Table[ListPolarPlot[data, Joined -> True, PolarAxes -> True, PolarAxesOrigin -> {p, Automatic}, PolarTicks -> {None, Automatic}, PlotLabel -> p], {p, {{Bottom, Left}, {Bottom, Right}}}]

将径向轴放在右上方，并角轴的半径是 5：

Wolfram Language code: SectorChart[{{2, 1}, {2, 3}, {3, 4}, {4, 2}}, PolarAxes -> True, PolarAxesOrigin -> {{Top, Right}, 5}]

巧妙范例  (1)

用滑尺移动极轴原点：

Wolfram Language code: Manipulate[PolarPlot[E ^ (θ / 10), {θ, 0, 30}, PolarAxesOrigin -> {angle, radius}, PolarAxes -> True, PolarTicks -> {"Degrees", Automatic}], {angle, 0, 2Pi, 0.1}, {{radius, 30}, 10, 40}]
