ComponentKeys

ComponentKeys

TimeSeriesおよびEventSeriesオプションで，成分のキーを指定する．

詳細

  • ComponentKeysは，通常，時系列または事象系列のデータ成分に命名するために使われる．
  • 次は，ComponentKeysの可能な設定である．
  • Automaticデータから成分キーを自動的に選択する »
    None単純な時系列あるいは事象系列を返す »
    {com1,com2,…}成分 comiを持つ時系列あるいは事象系列を返す »
  • TimeSeries[vals,times,keys]はTimeSeries[vals,times,ComponentKeyskeys]に等しい．

例  (2)

成分キー"a"と"b"で時系列を構築する：

Wolfram Language code: TimeSeries[{{.1, "cat"}, {.2, "dog"}, {.3, "fox"}}, {{Yesterday, Today, Tomorrow}}, ComponentKeys -> {"a", "b"}]

Tabularへの変換を使ってデータを表示する：

Wolfram Language code: Tabular[%]

満月と新月の日付のペアのリストから，事象系列を作成する：

Wolfram Language code: EventSeries[{{DateObject[{2026, 1, 3, 4, 2, 54.5329}, "Instant", "Gregorian", -6.], DateObject[{2026, 1, 18, 13, 51, 58.9335}, "Instant", "Gregorian", -6.]}, {DateObject[{2026, 2, 1, 16, 9, 14.7054}, "Instant", "Gregorian", -6.], DateObject[{2026, 2, 17, 6, 1, 9.07329}, "Instant", "Gregorian", -6.]}, {DateObject[{2026, 3, 3, 5, 37, 53.7335}, "Instant", "Gregorian", -6.], DateObject[{2026, 3, 18, 19, 23, 28.7273}, "Instant", "Gregorian", -6.]}}, {DateObject[{2026, 1}], Automatic, "Month"}, ComponentKeys -> {"FullMoon", "NewMoon"}]

Tabularへの変換を使ってデータを表示する：

Wolfram Language code: Tabular[%]

スコープ  (6)

明示的な成分キーを与える：

Wolfram Language code: TimeSeries[{{.1, "cat"}, {.2, "dog"}, {.3, "fox"}}, {{Yesterday, Today, Tomorrow}}, ComponentKeys -> {"a", "b"}]

Tabularへの変換を使ってデータを示す：

Wolfram Language code: Tabular[%]

与えられたリストが不完全な時は，自動的に成分キーが加えられる：

Wolfram Language code: TimeSeries[{{.1, "cat"}, {.2, "dog"}, {.3, "fox"}}, {{Yesterday, Today, Tomorrow}}, ComponentKeys -> {"number"}]
Wolfram Language code: ColumnKeys[%]

{}を与えることですべての成分キーを生成する：

Wolfram Language code: TimeSeries[{{.1, "cat"}, {.2, "dog"}, {.3, "fox"}}, {{Yesterday, Today, Tomorrow}}, ComponentKeys -> {}]
Wolfram Language code: ColumnKeys[%]

ComponentKeysのAutomatic設定は入力キーを保存する：

Wolfram Language code: Tabular[{{.1, "cat"}, {.2, "dog"}, {.3, "fox"}}, {"K1", "K2"}]
Wolfram Language code: tab = Tabular[Association["RawSchema" -> Association["ColumnProperties" -> Association["K1" -> Association["ElementType" -> "Real64"], "K2" -> Association["ElementType" -> "String"]], "KeyColumns" -> None, "Backend" -> "WolframKernel"], "Options" -> {}, "BackendData" -> Association["ColumnData" -> DataStructure["ColumnTable", {{TabularColumn[Association["Data" -> {{0.1, 0.2, 0.3}, {}, None}, "ElementType" -> "Real64"]], TabularColumn[Association[ "Data" -> {{3, {0, 3, 6, 9}, "catdogfox"}, {}, None}, "ElementType" -> "String"]]}}]]]];
Wolfram Language code: TimeSeries[tab, {{Yesterday, Today, Tomorrow}}, ComponentKeys -> Automatic]
Wolfram Language code: Tabular[%]

成分キーが与えられると，入力キーが無効になる：

Wolfram Language code: tab = Tabular[Association["RawSchema" -> Association["ColumnProperties" -> Association["K1" -> Association["ElementType" -> "Real64"], "K2" -> Association["ElementType" -> "String"]], "KeyColumns" -> None, "Backend" -> "WolframKernel"], "Options" -> {}, "BackendData" -> Association["ColumnData" -> DataStructure["ColumnTable", {{TabularColumn[Association["Data" -> {{0.1, 0.2, 0.3}, {}, None}, "ElementType" -> "Real64"]], TabularColumn[Association[ "Data" -> {{3, {0, 3, 6, 9}, "catdogfox"}, {}, None}, "ElementType" -> "String"]]}}]]]];
Wolfram Language code: TimeSeries[tab, {{Yesterday, Today, Tomorrow}}, ComponentKeys -> {"a", "b"}]
Wolfram Language code: Tabular[%]

成分キーがNoneに設定されていると，出力の時系列は明示的な成分がない簡単なものになる：

Wolfram Language code: tab = Tabular[Association["RawSchema" -> Association["ColumnProperties" -> Association["K1" -> Association["ElementType" -> "Real64"], "K2" -> Association["ElementType" -> "String"]], "KeyColumns" -> None, "Backend" -> "WolframKernel"], "Options" -> {}, "BackendData" -> Association["ColumnData" -> DataStructure["ColumnTable", {{TabularColumn[Association["Data" -> {{0.1, 0.2, 0.3}, {}, None}, "ElementType" -> "Real64"]], TabularColumn[Association[ "Data" -> {{3, {0, 3, 6, 9}, "catdogfox"}, {}, None}, "ElementType" -> "String"]]}}]]]];
Wolfram Language code: TimeSeries[tab, {{Yesterday, Today, Tomorrow}}, ComponentKeys -> None]
Wolfram Language code: Tabular[%]

入力キーがない場合，Automatic設定は単純な成分入力を保存する：

Wolfram Language code: TimeSeries[{{.1, "cat"}, {.2, "dog"}, {.3, "fox"}}, {{Yesterday, Today, Tomorrow}}, ComponentKeys -> Automatic]
Wolfram Language code: Tabular[%]

特性と関係  (2)

成分キーは第3引数またはオプションとして与えることができる：

Wolfram Language code: vals = {{.1, "cat"}, {.2, "dog"}, {.3, "fox"}}; times = {Yesterday, Today, Tomorrow}; keys = {"number", "animal"};
Wolfram Language code: TimeSeries[vals, {times}, keys]
Wolfram Language code: TimeSeries[vals, {times}, ComponentKeys -> keys] === %

引数として与えられた成分キーは，オプションによって与えられたそれを無効にする：

Wolfram Language code: TimeSeries[{{.1, "cat"}, {.2, "dog"}, {.3, "fox"}}, {{Yesterday, Today, Tomorrow}}, {"A", "B"}, ComponentKeys -> {"a", "b"}]
