[Gnuplot-info] no data point in gnuplot 4.0

[Guohan L. <lgu...@ma...>]

hi,
    I use 
    plot [] [0:] "rpt.raw" using 4:7:6:8 with yerrorbars lt -1, "le.raw"
using 4:7 title "RPT" with points lt 1 ps 0.6

    where "le.raw" may be null. My idea is that if  "le.raw" has no
data, gnuplot can simply ignore it and just
plot "rpt.raw", but gnuplot4.0 will error. 
	"le.mf", line 13: no data point found in specified file

    current, I just comment the line in plot2d.c, but I don't think it's
ugly. so, anybody can point to me the 
right way to solve the problem? Thx!
    pls c.c. to me.
