Re: [PyX-user] Fwd: How to reduce the file size ?

[Vignesh T G <vig...@gm...>]

Hello Michael and André,

Thank you for the replies and sorry for not providing an example.  I was
able to reduce the file size using Michael's suggestion, and the script is
given below


j = graph.graphxy(width=8, height=8,
                  x=graph.axis.lin(title=r"$\Delta y/R_o$ "),
                  y=graph.axis.lin(title=r"$\Delta{V}/Uc$"),
                  )

j.plot([graph.data.values(x=x, y=v,
                          title=r"$\Delta y/R$")],
       [graph.style.line([style.linestyle.dashed, style.linewidth.thin,
color.rgb.black])]
       )
j.writePDFfile('Eq_Behavior',write_compress=True)

Regards
Vignesh
