LaTex: How to change caption on figures from "Figure 1:" to "Figure 1 |"

Question

I have the following LaTex code below which generates a figure of a histogram:

\documentclass[review,12pt]{elsarticle}

\usepackage{lineno,hyperref}

\usepackage[utf8]{inputenc}
\usepackage[dvipsnames]{xcolor}
\usepackage{amssymb, lipsum, color}
\usepackage{graphicx}
\usepackage{subfigure}
\usepackage{comment}
\usepackage{smartdiagram}
\usetikzlibrary{shapes.geometric}
\usepackage{float}

\begin{document}

\begin{figure}[H]
\centering
\includegraphics[scale=0.8]{Histogram A.jpg}
\caption{Histogram Title}\label{Histogram A}
\end{figure}

\end{document}

I have attached a picture of the histogram here:

The caption on the histogram figure will start with Figure 1: Histogram Title. How do I change this to Figure 1 | Histogram Title? Ie. how do I replace the colon sign to a pipe sign?

Many thanks in advance!

Answer 1

Using the caption package:

\documentclass[review,12pt]{elsarticle}

\usepackage{lineno,hyperref}

\usepackage[utf8]{inputenc}
\usepackage[dvipsnames]{xcolor}
\usepackage{amssymb, lipsum, color}
\usepackage{graphicx}
\usepackage{subfigure}
\usepackage{comment}
\usepackage{smartdiagram}
\usetikzlibrary{shapes.geometric}
\usepackage{float}

\usepackage{caption}
\DeclareCaptionLabelSeparator{bar}{\space\textbar\space}
\captionsetup{labelsep=bar}

\begin{document}

\begin{figure}[htbp]
\centering
\includegraphics[scale=0.8]{example-image-duck}
\caption{Histogram Title}\label{Histogram A}
\end{figure}

\end{document}
