移动整个 Spirograph 绘图

我使用了以下代码，来自以下答案这个问题和这个问题，绘制螺旋图

在此处输入图片描述

tikzpicture 左侧有空白。我试图将整个绘图向左移动以使用这个未使用的空间。

我尝试了\begin{scope}[xshift=-2cm] ，\begin{scope}[shift={(180:2cm)}]和\tikzset{shift={(-2,0)}}，但是它们没有作用。

另外是否有可能简化移位代码 {scope}。

答案1

这是你想要的吗：

在此处输入图片描述

为此，我重新调整了tikzpicture环境的比例，以便图像适合，并将\hspace{-2em}环境稍微向左移动。

为了简化移位代码，可以使用循环\foreach。以下是更新后的代码：

\documentclass{beamer}
\beamertemplatenavigationsymbolsempty
\usepackage{tikz}
\usepackage{verbatim}
\begin{document}
\tikzset{pics/spiro/.style={code={
\tikzset{spiro/.cd,#1}
\def\pv##1{\pgfkeysvalueof{/tikz/spiro/##1}}
\draw[trig format=rad,pic actions]
 plot[variable=\t,domain=0:2*pi*\pv{nRotations}, samples=90*\pv{nRotations}+1, smooth cycle]
(
{(\pv{R}+\pv{r})*cos(\t)+\pv{p}*cos((\pv{R}+\pv{r})*\t/\pv{r})},
{(\pv{R}+\pv{r})*sin(\t)+\pv{p}*sin((\pv{R}+\pv{r})*\t/\pv{r})}
);
}},
spiro/.cd,R/.initial=6,r/.initial=-1.5,p/.initial=1,nRotations/.initial=1}

  \begin{tikzpicture}[line width=.06cm,scale=0.5]
    \foreach \x in {4.5,4,3.5,3,2.5,2,1.5,1,0.5,-4.5,-4,-3.5,-3,-2.5,-2,-1.5,-1,-0.5} {
       \begin{scope}[xshift=\x cm]
         (0,0) \pic[draw,blue,outer color=blue!80,inner color=blue!10,scale=.68]{spiro={p=1}};
