I need to change the size of a plot so that the text and line will be the correct size in my LaTeX document. I prefer to give LaTeX the correctly sized figure rather than scaling in LaTeX. I have writen a script that generates a GNUPLOT gp file. But the following command generates an error:

 

set term pdfcairo size 3in,4in 

 

I can get

 

set term png size 3in,4in  

 

but the final image quality is not good, i.e. it is not scalable like pdf or eps would be. I have also tried

 

set term post eps size 3in,4in

 

which also triggers an error.

 

I am processing the gp file in a script with the command

 

gnuplot --input="@tmpfile" --output="@output_file"

 

Thanks for any suggestions
