データの自動ラベル付け

ListPlotおよび関連関数は，LabelingFunctionをサポートするようになった．

In[1]:=

SeedRandom[3]; data = Accumulate@Table[RandomInteger[5], 12];

適切なメタデータがある場合，LabelingFunctionはラベルとして自動的にこれを使う．

In[2]:=

months = {"Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"};

In[3]:=

DateListPlot[data -> months, {2000, 1}, PlotMarkers -> {Automatic, 13}, ImageSize -> 550, Frame -> {{True, False}, {False, False}}, PlotTheme -> {"LargeLabels", "Business"}]

Out[3]=

LabelingFunctionでCalloutを使う．

In[4]:=

DateListPlot[data -> months, {2000, 1}, LabelingFunction -> Callout[ Automatic, Automatic], PlotMarkers -> {Automatic, 13}, ImageSize -> 550, Frame -> {{True, False}, {False, False}}, PlotTheme -> {"LargeLabels", "Business"}]

Out[4]=

データ点の上に，その点を中心にしてラベルを置く．

In[5]:=

opts = {PlotTheme -> {"LargeLabels", "Marketing"}, ImageSize -> 550, Frame -> {{True, False}, {False, False}}, PlotRangePadding -> Scaled[.05], Frame -> {{True, False}, {False, False}}};

In[6]:=

SeedRandom[4]; DateListStepPlot[ RandomReal[{0, 0.3}, 12] -> months, {2000, 1}, LabelingFunction -> Center, opts]

Out[6]=
