表示倍率
zoomFactorは、タイムスケールの表示倍率を示す数値です。 これを変更するには、タイムスケールのzoom関数を呼び出します。
拡大／縮小
タイムスケールを拡大／縮小することができます。
自動ズーム
また、タイムスケールの各層の目盛りのラベルに従って、タイムスケールを適切な倍率に自動的にズームすることもできる。
指定した表示倍率に変更
タイムスケールを特定の倍率に拡大または縮小することができます。
次のコードでは、タイムスケールをズームして、ビューポートにターゲットの日付範囲を表示します。 タイムスケールは最も近い目盛りで調整されることに注意してください。
タイムスケールの単位の調整
ズーム倍率に応じて、タイムスケールの階層の単位を適切な値に調整するかどうかを boolean値で設定します。デフォルト値はtrueです：
timescale.zoomIn(adjustTierUnit);
timescale.zoomOut(adjustTierUnit);
timescale.zoomTo(zoomFactor, adjustTierUnit);
timescale.zoomToRange(startDate, endDate, adjustTierUnit);
