I use eps format for good print quality. For the same reason I check "embed pdf & eps files" box before export to pdf.
In pdf file, the first species graph appears the right way round, but the second is return.
Have you any idea why this happens?
Convert Your eps file in ghostscript to pdf, and next import your pdf in place eps - it is my alternative to solve problem.
ps
Your eps files are in RGB mode, Do you want print Your files in print house?
If You need print it in print house, will be better convert files in ghostscript to cmyk pdf.
gs \
-sOutputFile=cmykfile.pdf \
-sDEVICE=pdfwrite \
-sColorConversionStrategy=CMYK \
-dProcessColorModel=/DeviceCMYK \
-sOutputICCProfile=yourprofile.icm \
rgbfile.pdf
EDIT:
Scribus can import graph as editable file too.
I attach the file.
Before import, in ghostscript I convert eps to ps with convert text to curves
option in gs -dNOCACHE -sDEVICE=ps2write, or pswrite
