填充溫度計

這裡的目標是將溫度計填充到所需的攝氏度或華氏度。當然，歡迎對下面的程式碼進行最佳化，就像我如何建立標籤或圖表本身一樣。這是 MWE：

答案1

最簡單的方法：

  1. 畫出秤的節點。
  2. 繪製/填充溫度計。
  3. 使用path picture和 聲明的節點填充溫度計的下部。

對於 53 °C，您可以使用

\path (C0) -- (C100) coordinate[pos=.53] (@aux);
\fill[red] (@aux) rectangle (path picture bounding box.south east);

對於華氏溫標，您可以使用相同的溫標，但需要事先計算位置（圖中未顯示的 0 °F 座標可能會有所幫助）。

除此之外，改進還有：

  • 一種形狀可以透過明確定義的錨點來實現這一點，這些錨點可用於放置刻度。 （我認為實現比例尺可能會帶來一項艱鉅的工作，因為人們可以用非常不同的風格繪製比例尺。）

  • 與上面相同，但在 TikZ 中而不是 PGF 中（不是形狀，而是帶有insert path一些選項，定義了一些可用於繪製比例的座標（「錨點」）。

答案2

這是最接近形狀的。這是一個insert path使用鍵值的解決方案。

希望它們是不言自明的。

新增密鑰scale name，以便最後繪製的溫度計具有獨立於密鑰的名稱 name。 （假設你畫了幾個溫度計。如果你想添加一個刻度，你很可能想在不同的路徑上使用它，這樣你就不會得到相同的畫線（儘管這可以通過使用 as 來避免edge）我才意識到）。

如果您想添加比四個角落更多的“錨點”，則需要添加coordinates。

您可以稍微調整一下角度值，看看它們會做什麼（不應該有任何意外，但不要使用零或非常大的值（儘管應該捕獲零））。

尺度僅被稱為left並right概括該方法。

底部圓的中心放置在最後一個路徑座標處（在我們的例子中是(0,0)）。

給定實現，tm scale人們可以輕鬆編寫一個\foreach使用給定值而不是計算出的相同大小值的循環。

這是一個嘗試，首先將路徑定義為宏，首先用於填充整個溫度計，然後剪輯溫度計的液體填充，最後繪製輪廓。您可以透過改變管線來改變液位\def\tempincelsius{55}。

}
\pgfmathdeclareoperator{c}{celcius}{1}{postfix}{600}
