我目前正在处理这张图片，这是代码。它用于显示第一象限中复数的乘法，显示长度和角度的变化。
\begin{tikzpicture}
\begin{polaraxis}[%
xmin=0,
xmax=90,
ymax=3,
xticklabel=$\pgfmathprintnumber{\tick}^{\circ}$,
ytick={0,1,2,3v},
yticklabel style={yshift=-13pt},
grid=both,
minor grid style={dashed,black!25},
major grid style=black,
minor tick num=1]
\addplot[->,red,very thick] plot coordinates {(0,0) (15,1.5)} node[right] {$z$};
\addplot[->,blue,very thick] plot coordinates {(0,0) (45,2)} node[right] {$v$};
\addplot[->,purple,very thick] plot coordinates {(0,0) (60,3)} node[left] {$zv$};
\addplot[->,blue,dashed,very thick] plot coordinates {(0,0) (45,3)} node[left] {$\left| z \right| v$};
\end{polaraxis}
\end{tikzpicture}
该代码基于我在这里找到的内容，但我正在尝试使其适应我以前所拥有的内容（尽管它不那么好）：
\begin{tikzpicture}
\begin{scope}[every node/.style={fill=white,inner sep=2pt}]
\draw (0,-3)--(0,3) node[above] {$Im$} (-03,0)--(3,0) node[right] {$Re$};
\draw[dashed] (0,0) circle (3) circle (2) circle (1);
\coordinate (a) at (30:1.5);
\coordinate (b) at (45:2);
\coordinate (c) at (75:3);
\coordinate (o) at (0:0);
\coordinate (x) at (0:1.5);
\draw (a) [blue] node[above right] {$z$};
\draw (b) [red] node[right] {$v$};
\draw (c) [purple] node[above right] {$zv$};
\draw (0,0)--(a) [blue, thick];
\draw (0,0)--(b) [red, thick];
\draw (0,0)--(c) [purple, thick];
\draw[dashed, red, thick] (0:0)--(45:3) node[above right] {$\left| z \right| v$};
\end{scope}
\pic[draw,dashed,blue,ultra thicangle radius=0.9cm,angle eccentricity=1.3] {angle=x--o--a};
\pic[draw,dashed,red,ultra thick,angle radius=0.8cm,angle eccentricity=1.3] {angle=x--o--b};
\pic[draw,dashed,purple,ultra thick,angle radius=0.7cm,angle eccentricity=1.3] {angle=x--o--c};
\draw (15:1) [blue] node[right] {$\theta$};
\draw (48:1) [red] node[right] {$\phi$};
\draw (76:1.1) [purple] node[above right] {$\theta+\phi$};
\draw (0:1) [black] node[below] {$1$};
\draw (0:2) [black] node[below] {$2$};
\draw (0:3) [black] node[below] {$3$};
\fill[blue] (a) circle (2pt);
\fill[red] (b) circle (2pt);
\fill[purple] (c) circle (2pt);
\fill[red] (45:3) circle (2pt);
\end{tikzpicture}
如何在第一段代码中将角度测量结果转换为“圆圈”？我还需要删除度数并将其转换为“Im”和“Re”

像这样？
