带箭头的线的频谱

Question

我正在尝试用阿拉伯语绘制类似于下面的光谱。我希望它有 10 个箭头。我还想缩小两个箭头之间的间隙。我的代码是：

注意：不要担心阿拉伯语。您可以全部用英语完成。我会完成阿拉伯语部分。

Answer 1

您可以使用double arrow如下形状：

\documentclass[tikz, border=1 cm]{standalone}
\usetikzlibrary {shapes.arrows, shadings, arrows.meta}
\begin{document}
\begin{tikzpicture}
\node[double arrow, double arrow head extend=.5cm, left color=cyan, right color=teal, text=white, font={\bf \Huge}, inner sep=0.3cm] (doublearrow) {DIRECTIVE\qquad NON-DIRECTIVE};
\draw[-{Triangle[scale=0.5]}, line width=2.5pt] (doublearrow.north -| -6,0) -- +(0,1)   node[above, align=center, font=\small]{Giving\\advice};
\draw[-{Triangle[scale=0.5]}, line width=2.5pt] (doublearrow.north -| 4,0) -- +(0,1)    node[above, align=center, font=\small]{Listening to\\understand};
\draw[-{Triangle[scale=0.5]}, line width=2.5pt] (doublearrow.south -| 1.5,0) -- +(0,-1) node[below, align=center, font=\small]{Reflecting};
\end{tikzpicture}
\end{document}

Answer 2

从这里开始

\documentclass[border=9,tikz]{standalone}
\usetikzlibrary{shadings}
\begin{document}
\begin{tikzpicture}
    \shade[left color=blue,right color=red, opacity=.2](0,-2)rectangle(6,2);
    \draw(0,1)--(4,1)--(4,2)--(6,0)--(4,-2)--(4,-1)--(0,-1)--cycle;
    \clip(0,1)--(4,1)--(4,2)--(6,0)--(4,-2)--(4,-1)--(0,-1)--cycle;
    \shade[left color=blue,right color=red](0,-2)rectangle(6,2);
\end{tikzpicture}
\end{document}
