简单情节中的错误台词

下图中为什么有一条水平线？如果在笛卡尔平面上绘制，水平线将沿着正方向绘制X-轴。每个命令都是画一个半圆或者给半圆上色。

该图形由 18 个半圆组成，其中 9 个位于X轴，其中九个位于X轴。每个圆弧从半圆上方X轴应与下方的圆弧对齐X轴。不过，这些弧线并不完全对齐。

看看此代码是否以所需的形式重现了您的图形：

\documentclass{amsart}
\usepackage[dvipsnames]{xcolor}
\usepackage{tikz}

\begin{document}
    \begin{tikzpicture}[x=0.25cm,y=0.25cm, very thin]
\draw[fill=Mahogany]    (-9,0) arc (180:0:9) arc (360:180:9);
\draw[fill=Red]         (-9,0) arc (180:0:9) arc (360:180:8) arc (0:180:1);
\draw[fill=RedOrange]   (-9,0) arc (180:0:9) arc (360:180:7) arc (0:180:2);
\draw[fill=orange]      (-9,0) arc (180:0:9) arc (360:180:6) arc (0:180:3);
\draw[fill=yellow]      (-9,0) arc (180:0:9) arc (360:180:5) arc (0:180:4);
\draw[fill=green]       (-9,0) arc (180:0:9) arc (360:180:4) arc (0:180:5);
\draw[fill=blue]        (-9,0) arc (180:0:9) arc (360:180:3) arc (0:180:6);
\draw[fill=Orchid]      (-9,0) arc (180:0:9) arc (360:180:2) arc (0:180:7);
\draw[fill=Purple]      (-9,0) arc (180:0:9) arc (360:180:1) arc (0:180:8);

在此处输入图片描述

笔记：每个形状都用一条闭合线绘制，并填充选定的颜色。在形状的边缘周围添加一条非常细的线，特别是在它们彼此非常接近甚至重叠的区域。
