将标签放置在相对于数据曲线的位置

Callout 和 Labeled 可以将标签放置在相对于数据曲线的已命名位置.

In[1]:=

options = Sequence @@ {Filling -> Axis, ImageSize -> 400}; data1 = Table[{k, PDF[BinomialDistribution[50, 0.2], k]}, {k, 0, 50}]; data2 = Table[{k, PDF[BinomialDistribution[50, 0.5], k]}, {k, 0, 50}]; data3 = Table[{k, PDF[BinomialDistribution[50, 0.7], k]}, {k, 0, 50}];

In[2]:=

ListPlot[{Callout[data1, "0.2", Above], Callout[data2, "0.5", Above], Callout[data3, "0.7", Above]}, options]

Out[2]=

In[3]:=

Grid[Partition[{ Plot[{Labeled[Sinc[x - 1], Sinc[x - 1], Above], Cos[x/1.1 + 0.3]/2}, {x, 0, 8}, ImageSize -> 250, PlotTheme -> "Business", PlotLabel -> "Above"], Plot[{Labeled[Sinc[x - 1], Sinc[x - 1], Below], Cos[x/1.1 + 0.3]/2}, {x, 0, 8}, ImageSize -> 250, PlotTheme -> "Business", PlotLabel -> "Below"]}, 2]]

位置可以用于 LabelingFunction 以便自动放置标签.

In[4]:=

data = Accumulate@Table[RandomInteger[5], 10]; ListLinePlot[data -> data, LabelingFunction -> Top, PlotMarkers -> Automatic, Filling -> Axis, PlotTheme -> "Business"]
