Ploticus 2.32 - 23 Aug '05 - New features

  • proc legend - support for multi-column or multi-row legends, word wrap for legend entries, backing box, title, and others. Thanks to Philippe Jalaber and Tobias Minich who suggested some of these features. Examples

  • proc venndisk - new proc for producing venn diagrams.
              example

  • textdetails - new linesep attribute to control line spacing.

  • mousover/tooltip labels can now be up to 1500 chars. Also any proc that had a clickmaplabel attribute now also has a clickmaplabeltext multiline attribute. This is to accomodate chunks of javascript code as used with SVG mouseover/tooltip method #2.

  • proc axis - month stub inc with datetime scaletype now supported.

  • proc pie - new wraplen attribute to wordwrap pie slice labels

  • new function - $rewritenum(f) which takes a numeric quantity f and returns it rewritten for display purposes, applying numbernotation (as specified in your proc settings or config file)

  • new function - $textwidth(f) returns horizontal width of FreeType bounding box. Useful only with freetype fonts, otherwise it returns 0. Suggested/contributed by Erik Zachte.

  • autorange - if user doesn't specify numformat, %f is now automatically used to build result with high magnitude low variance data sets (such as where the min is 1,000,000 and the max is 1,000,003).

  • Prefab parameters for access to some of the new proc legend features; and some other prefab items. More info

Bug fixes

  • date notations involving dots (such as dd.mm.yy) weren't being handled properly

  • gd16.c gcc 4 compile issue (static int cost, static int sint)

  • crosshatch lines were too thin w/ svg

  • proc bars - with 'truncate', bar completely out of range was suppressed but label still appears

  • drawcommands ignored cm units - fixed. Also, mark and cblock now accept posex specifications.

  • heatmap prefab - now supports title and related parameters.

  • superscripts in X axis stubs showed up on Y axis - fixed

  • autorange - now handles degenerate case where all data are 0

  • proc vector - instability if start and end points of a vector are same

  • proc getdata no longer does a popen( cat filename ) in CGI mode

  • strange color change problem - related to certain degenerate lineplots that don't draw anything. Bug in proc_lineplot.c fixed.

  • proc legend width attribute now supports cm

  • heatmap prefab - yaxis=none didn't have any effect. Fixed.

  • proc pie - with outlinedetails: none the labels and any associated lines disappeared

  • proc scatterplot - default clustermethod was horizontal when ylocation given.. and vertical when xlocation given.. seems like it should be the other way round.. so I changed it.

  • with datetime (others?) xautorange nearest=exact wasn't working

  • command line option -prefab is now disabled when operating in direct cgi mode

  • command line option -drawdumpa displayed to x11 but shouldn't
