How to concatenate strings in gnuplot?

Question

Let's say we have two strings:

String1 = 'This is '
String2 = 'a mouse.'

How can I concatenate these 2 strings to form the string 'This is a mouse.' in gnuplot?

Answer 1

Given two strings

String1 = 'This is ' 
String2 = 'a mouse.'

To concatenate them, you can use either

String3 = String1.String2

or a more flexible:

String3 = sprintf("%s%s", String1, String2)

type help string or help sprintf for more information about the two methods.
