I am using TikZ
to make a flow chart demonstrating my scheme step by step. I notice that the word wrapping is not automatic in a node. That is, the line can be extremely long across the whole page.
The MWE is as follows.
\documentclass[a4paper]{article}
\usepackage[english]{babel}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\usepackage{graphicx}
\usepackage[colorinlistoftodos]{todonotes}
\usepackage{tikz}
\title{Your Paper}
\begin{document}
\maketitle
\begin{tikzpicture}[block/.style={draw, fill=white, rectangle, minimum width=0.95*\columnwidth, anchor=west}, font=\small]
\node[block, minimum width=0.95\columnwidth, minimum height=1cm, fill=white, opacity=1, text opacity=1, rounded corners, thick](step1) at (0,0){};
\node[below=0cm of step1.north, align=left]{\textbf{Step 1}: This is Step one, which is a very very very long sentence. I really hate it when it does not automatically do the wrapping.};
\node[block, minimum width=0.95\columnwidth, minimum height=1cm, below right=0.9cm and 0cm of step1.south, fill=white, opacity=1, text opacity=1, rounded corners, thick](step2) at (0,0){};
\node[below=0cm of step2.north, align=left]{\textbf{Step 2}: Step 2 is cute and short.};
\draw[-stealth](step1.south)--(step2.north)node[pos=0.5, above=0cm]{};
\end{tikzpicture}
\end{document}
which renders as
My current workaround is to manually insert new line, which is very troublesome.
I, therefore, wish to find an elegant way to achieve the automatic word wrapping in a node of TikZ
.
align=left
to the node options and set atext width
.
