刪除 tikzpicture 上方的垂直空間

我試圖將兩張 tikz 圖片並排放置，但我在左邊的圖片上方有一個垂直空間！知道如何刪除空間嗎？

正如我在評論中所說，這裡的問題是，當您使用 繪製一條線時line width=X，邊界框會超出每條線的末尾 X/2 。所以當你這樣做時

\draw[color=blue!25, line width=184.5pt]  (4.247,0) -- (4.247,0.7);

此線的邊界框在 y=0 以下延伸 92.25pt。加上\draw (current bounding box.south east) rectangle (current bounding box.north west);繪製圖表的輪廓，您會發現右側圖表有很多空白。

除了使用不同的技術來繪製彩色矩形（例如 ）之外\fill[blue!25] (1,0) rectangle +(184.5pt, 0.7);，最簡單的修復可能只是將選項添加overlay到這些線條中，例如

\draw[color=blue!25, line width=184.5pt, overlay] (4.247,0) -- (4.247,0.7);

新增overlay至路徑後，計算邊界框時不會考慮該路徑。
