Hi,

org-babel-gnuplot-process-vars in ob-gnuplot.el makes a temporary file to store a table imported from the current org file using :var

However, the name of this file does not include the name of the variable or any similar field unique to the data. This means that if you want to plot data from two tables, they both get the same filename and consequently the second overwrites the first and the data is incorrect.

I switched line 103 from:

(org-babel-temp-stable-file (cons val params) "gnuplot-")


to:

(org-babel-temp-stable-file (cons val params) (concat "gnuplot-" (prin1-to-string (car pair)) "-"))


which includes the variable name into the generated filename and this appears to work for me.
