流星群のデータ

LabelingFunctionとCalloutを組み合せ．一定の条件を満たすデータだけにラベルを付ける．

In[1]:=

styles = {Joined -> False, Filling -> Bottom, FillingStyle -> Thick, PlotTheme -> "SingleAxis", PlotRange -> All, PlotStyle -> Yellow, LabelStyle -> White, Background -> Black, ImageSize -> 550};

In[2]:=

meteorData = MeteorShowerData[All, {"PeakDate", "PeakZHR", "Name"}]; meteorData = DeleteMissing[meteorData, 1, 1]; meteorData = meteorData[[All, ;; 2]] -> meteorData[[All, -1]];

In[3]:=

DateListPlot[meteorData, styles, FrameLabel -> {"Peak Date", "Peak Frequency"}, PlotLabel -> "Peak Dates and Frequencies of Meteor Showers, 2016", LabelingFunction -> (If[Last@# > 50, Callout[Last@Flatten[#3], Above], None] &)]
