温度计的填充物

温度计的填充物

这里的目标是创建一个填充温度计,以达到所需的摄氏度或华氏度。当然,欢迎对下面的代码进行优化,就像我如何创建标签或图表本身一样。这是 MWE:

答案1

最简单的方法:

  1. 绘制鳞片的节点。
  2. 绘制/填充温度计。
  3. 使用path picture和声明的节点填充温度计的下部。

对于 53 °C,您可以使用

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

对于华氏温标,您可以使用相同的方法,但需要事先计算位置(0°F 处未图示的坐标可能会有所帮助)。

除此之外,还可以进行以下改进:

  • 这种形状具有明确的锚点,可用于放置鳞片。(我认为实现鳞片可能会是一项大工程,因为人们可以用非常不同的风格绘制鳞片。)

  • 与上面相同,但在 TikZ 中而不是 PGF(不是形状,而是带有insert path一些选项,定义了一些可用于绘制比例的坐标(“锚点”)。

答案2

这是最接近形状的。这是insert path使用键值的解决方案。

希望它们是不言自明的。

添加键scale name是为了使最后绘制的温度计具有独立于键的名称 name。(假设您绘制了几个温度计。如果您想添加一个刻度,您很可能希望在不同的路径上使用它,这样您就不会得到相同的绘制线(尽管我刚刚意识到这可以通过避免edge)。)

如果您想添加比四个角更多的“锚点”,则需要添加coordinates。

您可以稍微调整一下角度值,看看它们会产生什么效果(应该不会有什么意外,只是不要使用零或非常大的值(尽管应该可以捕获零))。

这些量表仅被称为leftright概括该方法。

底部圆的中心位于最后一个路径坐标处(在我们的例子中是(0,0))。

鉴于实现,tm scale人们可以轻松编写一个\foreach使用给定值而不是计算相同大小的值的循环。
