[Gnuplot-bugs] plotting ASCII files

[Christian R. <Chr...@bg...>]

Dear Gnuplot developpers,

first, thanks for your continued development of this great software!

My computing center recently switched to version 4.2 (patchlevel 0, last =

modified March 2007, System: Linux 2.4.18-nec3.4p1.045). There is a=20
problem when plotting ASCII data files: Numbers with exponents with `d'=20
or `D' are wrongly handled (the exponent is ignored). I tested this by=20
just plotting the file

#----------------------------
1 0.05
2 5e-2
3 5d-2
#----------------------------

which plots (0.05, 0.05, 5.) rather than (0.05, 0.05, 0.05).

Best regards,
Christian R=F6denbeck.

That's because those are not valid ASCII representations of 
floating-point data.  Well, at least outside the FORTRAN world they 
aren't.  The support for such numbers was bogging down handling of more 
widely used data (i.e. those written by C programs), so it's now turned 
off by default.

See "help fortran".
