Version 2.04 - Released June 14, 2002

  • New - proc lineplot - clip attribute allows lineplot curve to be clipped to the plotting area.

  • New - proc lineplot - sort attribute for putting data into X order if necessary before plotting

  • New - clickmap support for SVG.

  • New - field names can now appear as legend labels. For the lines, stack, and vbars prefabs this will be the default if no name* parameters are specified and the data set contains a field name header. This feature can be used in scripts in proc bars, proc lineplot, proc curvefit by specifying #usefname for the legendlabel. Also available for proc scatterplot legendlabel.

  • New - script syntax - a backslash can now be used to indicate start of leading whitespace in a multiline text line

  • New - script syntax - if the name of an #included file begins with a dollar-sign ($), it is searched for in the ploticus prefabs directory. This provides a standard location for included files. See gallery example loglog as an example.

  • Docs - FAQ and dataformat man pages significantly updated; a new page about pre-press work also available.

  • Improved - config file errors now logged in CGI mode.

  • Fix - EPS bounding box is now expressed in integers and use of (atend) is avoided except when EPS is written to stdout. Problems had recently been reported with newer versions of GhostView complaining about floating point values in the bounding box.

  • Fix - CGI mode - QUERY_STRING used instead of REQUEST_URI

  • Fix - proc axis - problems involving numerical axis stubs when a thousands separator (eg. 100,000) is used. On win32, garbage was being appended. There was also incorrect interaction with stub format, especially trailing format characters.

  • Fix - dist prefab - title parameter wasn't working

  • Fix - the $frommin() function (dealing with time data) was unstable.

  • Fix - the limit for max # of categories (100 on each axis) was not being enforced, and max char length of a category has been raised to 78.

  • Fix - there was a slight amount of error in ploticus GD driver character widths.

  • Fix - zero-length data cells causing subsequent spurious "unplottable value" messages

  • Fix - proc pie max number of slices increased to 80.

  • Fix - proc settings incorrect interaction with page break

  • Fix - minor tics with datetime scaling not taking daily time window into consideration.

Version 2.03 - released on 4 March '02

This version includes many new features and bug fixes.
  • Fixed bug - cgi mode - CGI SECURITY RISK - command line arguments that were insecure or inappropriate in CGI mode are now disabled when in CGI mode.

  • pltab has been discontinued.

  • Improvement - cgi mode - If -debug is specified all diagnotistic and error msg output automatically goes to specific files. This should simplify debugging in CGI mode.

  • New feature - client-side imagemaps

  • Improvement - proc datesettings has been expanded and renamed to proc settings. This proc can now be used to make most settings that previously required a config file.

  • Improvement - proc bevelrect has been renamed to proc rect, and should now be thought of as the preferred way to draw arbitrary shaded rectangles.

  • Changed: #proc endproc may now be written #endproc. The old syntax will also continue to work.

  • New feature - proc areadef categories - new modifier selectrows which allows categories to be taken from data field based on a conditional expression.

  • New attribute - proc processdata - outfile allows result to be written to a file. This came up because a user wanted to perform arithmetic (a la getdata filter) to processdata result, and there was no way to do it.

  • New feature - proc annotate can now do drop shadows, beveling, and colored backing box with or without outline.

  • New attribute - proc getdata - pf_fieldnames for defining post-filter fieldnames.

  • Improvement - max number of legend entries raised to 80 (was 30).

  • New attribute - config and proc settings - numberspacerthreshold controls when thousands separator characters begin to appear.

  • New system variable - CM_UNITS - indicates if working in -cm mode or not.

  • Improvement - special #include statements that refer to the prefabs directory (filename beginning with $) may be used any time, not just with -prefab. This will make it easier to copy prefab scripts into other directories for customization.

  • Fixed bug - pl crashes when reading any config file.

  • Fixed bug - prefabs were not working in CGI mode.

  • Fixed bug - script lines longer than 255 were overflowing. The published script line length limit is 3000.

  • Fixed bug - cm mode - cm conversion was not being done on ploticus variables that hold generated absolute coordinate values (eg AREALEFT). Position of prefab titles was affected.

  • Fixed bug - proc processdata - count action - the counts for highest and lowest category were off by 1.

  • Fixed bug - problem with date formats containing dashes (eg. dd-mmm-yyyy) when setting up plotting area and data space.

  • Fixed bug - number display - large number 000 separators interacting incorrectly with stub formatting.

  • Fixed bug - times - the displayable seconds component of time values was being shown as a value between 0.0 -> 1.0 rather than 0 -> 60.

  • Fixed bug - times - data values having a seconds component > 59.0 (eg. 59.3) were considered invalid.

  • Fixed & improved - times - noon and/or midnight were displayed incorrectly when hha format was being used. Noon is now represented as 12n and midnight is represented as 12am.

  • Fixed bug - proc legend - incomplete legend when specifyorder has more entries than the number of legend entries.

  • Fixed bugs - cm mode - certain objects were too small in -cm mode, including default prefab plot size, various hard-coded prefab sizes, and default symbol size.



Version 2.02 - Jan 11, '02

  • HTML server-side imagemap support has been added.

  • The data parsing code has been rewritten, and now allows situations that weren't allowed before, such as blank fields (tab or .csv formats), and variable number of fields per row. The dataformat documentation has also been improved.

  • new attribute - proc getdata - nfields - Controls the expected number of fields per record.

  • new attribute - proc getdata - fieldnamerows - like fieldnames but allows data field names to be given one per line.

  • modified attribute - proc getdata - delim - There is now a distinction between whitespace delimitation with quoted strings (spacequoted) and pure whitespace delimitation (whitespace). whitespace is faster, but the default remains spacequoted (space for short) so that existing scripts don't break. More info.

  • new attribute - proc lineplot - gapmissing - allows missing data points to cause a gap in the curve. Similar parameter added to lines and chron prefabs.

  • new attribute - proc scatterplot - clustermethod - control how duplicate points will be clustered.

  • new attribute - proc scatterplot - symfield and symrangefield - allows symbol shape, color, etc. to be controlled by a data field.

  • new attribute - proc scatterplot - dupsleg allows symbol shape, color, etc. to be controlled by degree of duplicity

  • prefabs - added rectangle as a standard parameter. It controls plotting area size (and location, if rendering in paginated postscript).

  • lines prefab - changed the way that the fill parameter works. Previously it had applied to all curves and line color was used. Now it is specified as a color, and separately for each curve (using fill2, fill3, and fill4). Note: this will break any existing applications that use the lines prefab to render multiple filled curves.

  • The directory for prefab files can now be hard-coded at build time, settable in the Makefile. If this is done then users don't need the PLOTICUS_PREFABS environment variable to be set. This capability is not available on win32 builds.

  • a new prefab called draw has been added. It interprets ploticus draw commands.

  • some new functions, including $numgroup() and $dategroup() which are useful in grouping a set of numbers or dates into bins.

  • the internal name lookup scheme for function names has been changed, and is now a little more efficient.

  • fixed bug: proc bars - stacked bars are drawn incorrectly when minima is non-zero. Eg. stacked vertical bars are incorrect if the plotting area Y min is non-zero.

  • fixed bug: proc bars - stacked bars - clobber bug causing core dump on linux.

  • fixed bug: datetime scaling - floating point rounding problem. Came to light when user tried to autorange on a datetime field and was getting a minima time of 06:59 when it should have been 07:00.

  • increased the size of file pathname variables from 127 to 255 and doing length checking on script file and output file name



    Version: 2.01 (16 Nov '01)

    New features:
    • SVG capabilities. The driver was written by Bill Traill.

    • The Makefile has been reworked. Before building ploticus you edit the Makefile and follow a simple 3-step procedure. There are more build variations than before.

    • Source code can now be compiled on win32 using mingW and maybe other compilers. More info.

    • postscript - ISO Latin1 encoding added, so that European characters may be produced in postscript exactly like they are in the other environments (ascii 128-255).

    • Created graphic files are automatically chmod'ed to mode 644.
    Bug fixes:
    • Some code problems related to the new CGI functionality have been cleaned up. These may have caused problems on some platforms.

    • proc getdata filter - data field names within proc getdata filter statements were not working. Fixed.

    • dates - dates earlier than 1977 causing problems with autorange and probably in other areas. This has been fixed to handle dates back to Jan 1 1800.

    • general - most command line args including var=value pairs were being retained in a 200 character buffer, a problem when command lines are longer. Fixed.

    • proc bars - problems with bar labeling when select is used; also clustering should work with segment bars. Fixed.




    Version: 2.00 (18 Sep '01)

    This major release introduces prefabs for creating standard types of plots directly from the command line, CGI mode, and optional JPEG, WBMP, and FreeType2 support. The script interpreter code has been completely replaced; a general clean-up pass was applied to all code.

    Specific new features:
    • Prefabs

    • CGI mode

    • Optional JPEG, WBMP, and FreeType2 support, however you must link to your own copy of GD library version 1.84 or higher when you build ploticus, and have the other required libs. See the Makefile for more info. Thanks to Michael Tonkin for getting the ball rolling on this. Here's an example that uses a TrueType sans serif font.

    • A new script interpreter. New flow of control operators including: #elseif #else #for #while #setifnotgiven #call #write #shell, etc. Also, increased capacities for data fields and variables (250 chars) and script input lines (3000). The new interpreter involves some script syntax changes that may cause existing scripts to break in some cases.

    • General code clean-up and efficiency improvements (thanks for the suggestions.. who wrote that code, anyway?!).

    • #sql, a new directive for retrieving data directly from an SQL database. This is currently under development, and user-contributed client interfaces to DBMSs such as MySQL and Oracle would be welcome (the code is in dbinterface.c)
    A number of minor improvements and bug fixes are also present:
    • Added: proc areadef autorange - new subattributes selectrows (for selecting rows to be considered when scanning for min and max) and combomode (to allow correct finding of min and max for situations like error bars and stacked bars).
    • Added: proc areadef autorange - now sets variables DATAXMIN, DATAXMAX, DATAYMIN, and DATAYMAX - the actual minima and maxima of data field.
    • Added: proc axis - stubevery attribute
    • Added: proc getdata - pathname attribute, to specify data file name directly without involving cat(1)
    • Added: proc bars - colorfield attribute - set bar color based on a data field
    • Added: proc legendentry - tag attribute
    • Added: various new functions
    • Added: the temp file default path name and default slash character can now be changed in pl.h or in a config file.
    • Added: resource utilization (cpu time and size of created disk files) now can be controlled. Default upper limits are 10 cpu seconds and 5,000,000 bytes. Limits may be altered in pl.h or by using a config file
    • Added: various other config file settings
    • Changed: proc axis - minor changes to avoid orphan date stubs and improper year placement (autoyears)
    • Fixed bug: proc axis - when producing stubs running from negative to positive zero is displayed as a very tiny non-zero value such as 5.2579e-17 due to rounding error.
    • Fixed bug: proc getdata - buffer overflow when 'filter' is used with data records longer than 254 chars, causing garbage result or instability.
    • Fixed bug: proc legend - legend entry text could not be adjusted using textdetails \fCadjust=\fR
    • Fixed bug: proc bars - select omits bars but not labels. Thanks to Dan Tsafrir for finding this one.
    • Fixed bug: $arith() function - detects and issues an error on divide-by-zero.


    Ploticus is 2 years old - 25 Aug '01


    Ploticus version 1.41: 18 Jun '01

    • Ploticus now covered under .

    • proc bars - additional (diagonal) cross hatching available as an accessory (see d ownload page)
    • Fixed bug: colored background not completely filling the result window when scale is being done

    • Fixed scripts in test suite: The change in default size (version 1.40) sometimes caused general layout problems with graphics that were layed out with an 8.5" x 11" default size in mind. The solution for these scripts is to add a #proc page and specify pagesize: 8.5 11. Some of the scripts in the test suite had such problems and are now fixed.

    • Fixed bug: EPS bounding box incorrect for 1) pltab output and 2) pl where result draws into negative absolute coordinate space.

    • Fixed bug: proc areadef xautorange/yautorange not working correctly in some cases when a nearest= value is specified. This bug was apparently introduced in 1.40.

    • Fixed bug: proc lineplot - accum option choking when non-numeric data encountered.

    • Fixed bug: proc rangebar - negative barloc values not working.

    • Added: proc areadef - autorange datafield may now be a comma-delimited list of dfields so that multiple data fields are considered when determining the axis min and max.

    • Changed: scaletypes - times hh:mm:ss and mm:ss - validity checking relaxed slightly to allow degenerate values such as 0:4:9

    • Fixed bug: pltab - incorrect interaction between #font and sectionheadings

    • Fixed bug: proc rangebar - textdetails controls N= label but not missing label

    • Fixed bug: pltab - creates 8.5 x 11 inch gif, png regardless of result size

    • Fixed bug: axis - line grid and gridblock starting point incorrect in X

    • Fixed bug: axis - colors incorrect when specified in certain combinations for tics, stubs, grid

    • Fixed bug: bars - ticks not being drawn when truncating was not switched on

    • changed: .pls is now a "known extension" for script files.
    • changed: improved the heuristic for automatic axis increment determination

    • fixed bug: proc scatterplot - if select condition used or if values are out-of-range, labels from data and datapoint size from data may be incorrect due to data alignment bug.
