- Enhanced text mode accepts
U+xxxx (xxxx is a 4 or 5 character hexadecimal)
as representing a Unicode code point that is converted to the corresponding
UTF-8 byte sequence on output.
- The character sequence $# in a using specifier evaluates to the total
number of columns available in the current line of data. For example
"plot FOO using 0:(column($# - 1))" plots the last-but-one field of each row.
- Time/date input recognizes format %p to handle am/pm field
- plot titles are evaluated *after* plotting, rather than before. This allows
the title to reference quantities calculated while plotting.
- Built-in modified Bessel functions (besi0 besi1 besin)
- Built-in order N Bessel functions of the 1st and 2nd kind (besjn besyn)
- (5.4.2) in "using" context, $# means "number of columns in current data line"
- (5.4.2) "plot with fillsteps {above
below y=
value
}" analogous to filledcurves
- (5.4.3) "nogrid" flag allows splot components to opt out of dgrid3d processing
- (5.4.3) "set style histogram nokeyseparators" (see newhistogram (p.
))
- (5.4.5) column(0) returns the linear ordering of nonuniform matrix elements.
Thus for element A[i,j] in an MxN matrix,
column(0) / M gives the row index i
column(0) % M gives the column index j
- (5.4.5) Component boxes in "plot with histograms" can be colored according to
a separate column of category/color information. See lc variable (p.
).
- (5.4.5) Fix a regression in version 5.4.4 that caused string-
int promotion
to incorrectly assume a leading 0 implies an octal number
- (5.4.5) The position of the key box can be manually tweaked by giving an
offset added to whatever position the program would otherwise use.
See set key offset (p.
).
- (5.4.6) New set key options force exact number of columns, exact key width.
