% Some macros for drawing gantt diagrams using tkiz.
|
|
%
|
|
% Martin Kumm, 17.05.2010 (Version 1.0)
|
|
% Alan Munn, Martin Kumm, 14.03.2011 (Version 1.2)
|
|
% Andrés Silva Marambio, 20.03.2011 (Version 1.3)
|
|
%
|
|
% Update 20.03.2011, Version 1.3
|
|
%
|
|
% changes from v1.2:
|
|
% change \ProvidesPackage{gantt.sty} for \ProvidesPackage{gantt}
|
|
% add \bfseries for the command \ganttgroup
|
|
% add two newcommands for doing Gantt Milestones: \ganttmilestone and \ganttmilestonecon
|
|
% usage: \ganttmilestone[color=<color>]{label}{start} - Create a gantt milestone using a diamond
|
|
% usage: \ganttmilestonecon[color=<color>]{label}{start} - Create a gantt milestone using a diamond and conect with the previuos itemg
|
|
% fixed the issue when \ganttbarcon or \ganttmilestonecon connect in decimal positions
|
|
%
|
|
% Update 15.03.2011, Version 1.2
|
|
%
|
|
% changes from v1.1:
|
|
% px sizes has ben changed ot pt due to problems with some LaTeX distributions (thanks to Michael Kubovy and Loïc Le Guyader!)
|
|
% Correction of the text aligned in \titleelement (thanks to Josh Hykes!)
|
|
% \unitlength was changed to \ganttunitlength (thanks to Alan Munn!)
|
|
% \RequirePackage was added (thanks to Alan Munn!)
|
|
%
|
|
% Update 05.08.2010, Version 1.1
|
|
%
|
|
% changes from v1.0:
|
|
% \ganttbar and \ganttbarcon have been extended with the xkeyval syntax
|
|
% The pattern of the bar is now independent of the color and can be set by
|
|
% e.g. \ganttbar[pattern=horizontal lines,color=blue]{...}{1}{1}
|
|
% This syntax is incompatible with the previous ones!
|
|
% replace \ganttbar[<pattern>] with \ganttbar[pattern=<pattern>]
