tikzpicture で 2 つのタイムラインを作成しますか?

Question

tikzpicture で 2 つのタイムラインを作成しようとしています。上のタイムラインは希望どおりに見えますが、下のタイムラインでは問題が発生しています。小さな垂直の目盛りの代わりに、大きな対角線が生成されます。

何が間違っているのでしょうか、どうすれば修正できるでしょうか?

ありがとう！

Answer 1

垂直線の座標を明示的に定義します。

したがって、最初の垂直線は次のようになります。

\foreach \x in {0, 5, 10, 19, 30, 40}{
   \draw (\x/2,-0.2) -- (\x/2,0.2);
}

そして2番目のセットは

\foreach \x in {0, 5, 10, 19, 30, 40}{
   \draw (\x/2,-2.2) -- (\x/2,-1.8);
}

Answer 2

2 番目のケースでは、垂直線の y 座標の計算が間違っています。最初のケースでは、水平線の高さが であるため、計算は機能します0。2 番目のケースでは、オフセット を追加する必要がありますが-2、これは -library を使用して実現できますcalc。
