Allows labeling of events with per day granularity. Other features include relative positioning with unit specification, adjustable tick mark step size, and scaling to specified width. % \end{abstract} % % \section{Introduction} % Most timeline packages and solutions for {\LaTeX} are used to convey a lot of information and are therefore designed vertically. If you are just attempting to assign labels to dates, a more traditional timeline might be more appropriate. That's what {\jobname} is for. % % \section{Usage} % \DescribeEnv{chronology} % Declare a |chronology| as follows: % \begin{alltt}\verb|\begin{chronology}|\oarg{step}\marg{startYear}\marg{endYear}\marg{unit}\marg{width}\\\meta{events}\\\verb|\end{chronology}|\end{alltt} % Where \marg{width} is the final width of the timeline. The width can be specified as a command (e.g.\ \cmd{\textwidth}). \marg{unit} specifies the distance between minor ticks. \oarg{step} (unitless) specifies how many units between major ticks, where the first starts $\equiv_{\bmod {\langle step\rangle}}0$. The timeline runs from \marg{startYear} to \marg{endYear}. % \DescribeMacro{\event} % Label an \cmd{\event} as follows: % \begin{alltt}\cmd{\event}\oarg{startDate}\marg{endDate}\marg{label}\end{alltt} % An \cmd{\event} with the label \marg{label} is created. If \oarg{startDate} is specified the \cmd{\event} should span to \marg{endDate}, otherwise the \cmd{\event} specifies a specific date. All dates are unitless. % \DescribeMacro{\decimaldate} % Specify a \cmd{\decimaldate} as follows: % \begin{alltt}\cmd{\decimaldate}\marg{day}\marg{month}\marg{year}\end{alltt} % % \StopEventually{\PrintChanges\PrintIndex} % % \section{Implementation} % \iffalse %<*package> % \fi % % \begin{environment}{chronology} % |chronology| creates the graphic first and then scales it to size. Using a large unit size results in a large prescaled graphic, and therefore finer postscaled details. % \begin{macrocode} \newenvironment{chronology}[5][5]{% \newcounter{step}\newcounter{stepstart}\newcounter{stepstop}% \newcounter{yearstart}\newcounter{yearstop}\newcounter{deltayears}% \newlength{\xstart}\newlength{\xstop}% \newlength{\unit}\newlength{\timelinewidth}% \setcounter{step}{#1}% \setcounter{yearstart}{#2}\setcounter{yearstop}{#3}% \setcounter{deltayears}{\theyearstop-\theyearstart}% \setlength{\unit}{#4}% \setlength{\timelinewidth}{#5}% \pgfmathsetcounter{stepstart}% {\theyearstart+\thestep-mod(\theyearstart,\thestep)}% \pgfmathsetcounter{stepstop}{\theyearstop-mod(\theyearstop,\thestep)}% \addtocounter{step}{\thestepstart}% \newsavebox{\timelinebox}% \begin{lrbox}{\timelinebox}% \begin{tikzpicture}[baseline={(current bounding box.north)}]% \draw [|->] (0,0) -- (\thedeltayears*\unit+\unit, 0);% \foreach \x in {1,...,\thedeltayears}% \draw[xshift=\x*\unit] (0,-.1\unit) -- (0,.1\unit);% \addtocounter{deltayears}{1}% \foreach \x in {\thestepstart,\thestep,...,\thestepstop}{% \pgfmathsetlength\xstop{(\x-\theyearstart)*\unit}% \draw[xshift=\xstop] (0,-.3\unit) -- (0,.3\unit);% \node at (\xstop,0) [below=.2\unit] {\x};}}{% \end{tikzpicture}% \end{lrbox}% \raisebox{2ex}{\resizebox{\timelinewidth}{!}{\usebox{\timelinebox}}}}% % \end{macrocode} % \end{environment} % % \begin{macro}{\event} % \begin{macrocode} \newcommand{\event}[3][e]{% \pgfmathsetlength\xstop{(#2-\theyearstart)*\unit}% \ifx #1e% \draw[fill=black,draw=none,opacity=0.5]% (\xstop, 0) circle (.2\unit)% node[opacity=1,rotate=45,right=.5\unit] {#3};% \else% \pgfmathsetlength\xstart{(#1-\theyearstart)*\unit}% \draw[fill=black,draw=none,opacity=0.5,rounded corners=.2\unit]% (\xstart,-.2\unit) rectangle% node[opacity=1,rotate=45,right=.5\unit] {#3} (\xstop,.2\unit);% \fi}% % \end{macrocode} % \end{macro} % % \begin{macro}{\decimaldate} % \begin{macrocode} \newcommand{\decimaldate}[3]{(#1-1)/31/12+(#2-1)/12+#3} % \end{macrocode} % \end{macro} % \iffalse % % \fi % % \Finale \endinput
