GFx New Features
The point and click version of GFx has several new features which
are listed below.
- Character Delimited File Format
- GFx will now read and write files that use delimiter characters to
separate the data columns. The current choices are a comma, space or a
tab character as the delimiter. The scaling information at the end of
the file is still in the standard GFx format. The number of points line
at the top of the file is still automatically detected. It is assumed
that a line with no delimiters at the top of the file contains the
number of points in the file. In the case of a space character
delimiter, multiple spaces are assumed to be a single delimiter. The
other delimiters are assumed to be single characters only. Spaces at
the beginning or ends of a line are also ignored.
- New treatment of invec length=0
- The previous version of GFx would insist on writting files with the
invec length nonzero. The current version will now let you write
invec=0 files, with a warning if you have multiple data segments.
Character delimited data always has invec=0, use the standard GF format
if you want invec non-zero.
- Postscript Line Join control
- On the profile form there is a list box for the type of joining to
use between line segments in the postscript output. The default of
round will only produce strange results on very think lines. The miter
choice may make some data look artifically noisy.
- Color White added
- This may seem like a stupid color to use, but a planned upgrade
will allow GFx to plot over images and then white may be needed to make
comments show. Here's an
