[Gnuplot-info] GNUplot issue with characters separators and output images

[Geoffrey D. <gd...@gm...>]

GNUPlot special characters and blank image

All,

I am trying to generate a GNUPlot graph for the first time and I am facing
the following issues:
1. I need to use 2 types of character separators: space and an invisible
character with HEX code "A0 31 30 A0".
If I try to run the following command, I don't know how to mention the above
HEX code and I get an error because of the {} characters:

gnuplot> set datafile separator {whitespace | "\t"}
                                ^
         invalid complex constant

The file that contains the sepcial characters is available enclosed.

2. Withtout this characters issue, the output displayed is OK, but if try to
generate an image it's output is always empty (0 bytes).

gnuplot> set output "test.png"

Could you please help me with the above commands so that I can successfully
generate my graph?

Thank you,
Geoffrey
