New Members ⇒ Help me in figure caption citation

[Dharam]

Hi everyone,

I am Dharam Rabari, new member on latex forum.

I have prepared one article in latex using following documentclass

Code: Select all

\documentclass[preprint,sort&compress,12pt]{elsarticle}
\usepackage{natbib}

Using, sort&compress, I am happy with sorting and compression in main document. I want to cite one figure caption. I have used,
\caption{Equilibrium data\cite{ref1,ref2,ref3,ref4}}

I got the output "Fig. 1 Equilibrium data[3,9,18,19]"
It means sorting is ok but citing is not compressed. I want following output

"Fig. 1 Equilibrium data[3,9,18-19]"

I have used \protect\cite{} in place of \cite{} but same result.

Please help me. Thanks in Advance...

Hi and welcome,
can you extend the information you have given to a compilable example, making it easy for helpers to just copy/paste/compile and test possible solutions?
