### ganttchart Environment

Source: https://context7.com/skafdasschaf/latex-pgfgantt/llms.txt

The primary environment for defining a Gantt chart, requiring start and end time slots.

```APIDOC
## ganttchart Environment

### Description
The main environment for creating Gantt charts. It accepts two mandatory arguments specifying the start and end time slots, plus optional styling parameters.

### Parameters
#### Path Parameters
- **start_slot** (integer/date) - Required - The starting time slot of the chart.
- **end_slot** (integer/date) - Required - The ending time slot of the chart.

### Request Example
\begin{ganttchart}[hgrid, vgrid]{1}{12}
    \gantttitle{Project}{12} \\
    \ganttbar{Task}{1}{5}
\end{ganttchart}
```

--------------------------------

### Define Custom Gantt Chart Time Slot Formats

Source: https://context7.com/skafdasschaf/latex-pgfgantt/llms.txt

Allows defining custom time slot formats for specialized date requirements beyond built-in options. Example shows a 'day of year' format.

```latex
% Define a "day of year" format (year.dayofyear)
\newgantttimeslotformat{dayofyear}{\def\decompose##1.##2\relax{\def\theyear{##1}\def\theday{##2}}
    \decompose#1\relax%
    \pgfcalendardatetojulian{\theyear-01-01}{#2}%
    \advance#2 by-1\relax%
    \advance#2 by\theday\relax%
}

\begin{ganttchart}[
    hgrid, vgrid,
    time slot format=dayofyear
]{2024.1}{2024.31}
    \gantttitlecalendar{month=name, day} \\
    \ganttbar{January Tasks}{2024.5}{2024.25}
\end{ganttchart}
```

--------------------------------

### Use Linked Commands for Sequential Tasks

Source: https://context7.com/skafdasschaf/latex-pgfgantt/llms.txt

Simplifies creating sequential tasks by automatically linking them. Use `ganttlinkedbar`, `ganttlinkedgroup`, and `ganttlinkedmilestone`.

```latex
\begin{ganttchart}[vgrid, hgrid]{1}{20}
    \gantttitlelist{1,...,20}{1} \\

    % First task (no link)
    \ganttbar{Kickoff}{1}{2} \\

    % Automatically linked sequence
    \ganttlinkedbar{Planning}{3}{5} \\
    \ganttlinkedbar{Design}{6}{8} \\
    \ganttlinkedmilestone{Design Review}{8} \\
    \ganttlinkedbar{Implementation}{9}{14} \\
    \ganttlinkedbar{Testing}{15}{18} \\
    \ganttlinkedmilestone{Release}{20}
\end{ganttchart}
```

--------------------------------

### Add task bars

Source: https://context7.com/skafdasschaf/latex-pgfgantt/llms.txt

Shows basic task bars, custom styling, progress indicators, and empty labels.

```latex
\begin{ganttchart}[
    vgrid,
    hgrid,
    bar/.append style={fill=blue!30},
    bar height=0.5,
    bar top shift=0.25
]{1}{12}
    \gantttitlelist{1,...,12}{1} \\

    % Basic bar with label
    \ganttbar{Task 1}{1}{4} \\

    % Bar with custom styling
    \ganttbar[
        bar/.append style={fill=green!50, rounded corners=3pt},
        bar label font=\bfseries\color{darkgreen}
    ]{Task 2}{5}{9} \\

    % Bar with progress indicator
    \ganttbar[progress=60]{Task 3}{3}{10} \\

    % Empty label bar
    \ganttbar{}{10}{12}
\end{ganttchart}
```

--------------------------------

### Add Today Marker and Vertical Rules

Source: https://context7.com/skafdasschaf/latex-pgfgantt/llms.txt

Use the today key for date markers and the ganttvrule command for custom vertical reference lines.

```latex
\begin{ganttchart}[
    vgrid, hgrid,
    % Today marker
    today=5,
    today offset=0.5,
    today label=Today,
    today label font=\itshape\color{blue},
    today rule/.style={draw=blue, ultra thick, dashed}
]{1}{12}
    \gantttitlelist{1,...,12}{1} \\

    \ganttbar{Task 1}{1}{4} \\
    \ganttbar{Task 2}{3}{8} \\
    \ganttbar{Task 3}{7}{12}

    % Custom vertical rules for deadlines
    \ganttvrule{Deadline 1}{4}
    \ganttvrule[
        vrule/.style={draw=red, thick},
        vrule label font=\bfseries\color{red}
    ]{Final Deadline}{10}
\end{ganttchart}
```

--------------------------------

### Apply Global Configuration with ganttset

Source: https://context7.com/skafdasschaf/latex-pgfgantt/llms.txt

Use ganttset to define consistent styles globally or override them within specific chart scopes.

```latex
% Global configuration
\ganttset{
    hgrid,
    vgrid,
    x unit=0.5cm,
    bar/.append style={fill=blue!30, rounded corners=2pt},
    group/.append style={fill=orange!50},
    milestone/.append style={fill=red!70},
    link/.style={-latex, thick}
}

\begin{ganttchart}{1}{12}
    \gantttitlelist{1,...,12}{1} \\
    \ganttgroup{Project}{1}{12} \\
    \ganttbar{Task 1}{1}{4} \\
    \ganttlinkedbar{Task 2}{5}{8} \\
    \ganttlinkedmilestone{Done}{10}
\end{ganttchart}

% Override locally
\begin{ganttchart}[bar/.append style={fill=green!30}]{1}{6}
    \gantttitlelist{1,...,6}{1} \\
    \ganttbar{Different Style}{1}{4}
\end{ganttchart}
```

--------------------------------

### Sequential Element Commands

    group peaks height=0.3,
    group peaks tip position=0.5
]{1}{16}
    \gantttitlelist{1,...,16}{1} \\

    % Main project group
    \ganttgroup{Project Alpha}{1}{16} \\

    % Phase groups with subtasks
    \ganttgroup{Phase 1: Planning}{1}{5} \\
    \ganttbar{Requirements}{1}{3} \\
    \ganttbar{Design}{3}{5} \\

    \ganttgroup{Phase 2: Development}{6}{12} \\

\usetikzlibrary{decorations.pathmorphing}

% Define a wavy link type
\newganttlinktype{wavy}{
    \ganttsetstartanchor{on right=0.5}
    \ganttsetendanchor{on left=0.5}
    \draw [decorate, decoration={snake, amplitude=2pt, segment length=8pt},
           thick, -latex, blue]
        (\xLeft, \yUpper) -- (\xRight, \yLower);

    % Fixed progress values
    \ganttbar[progress=100]{Completed}{1}{3} \\
    \ganttbar[progress=50]{Half Done}{2}{6} \\
    \ganttbar[progress=0]{Not Started}{7}{10} \\

    % Automatic progress based on today marker
    \ganttbar[progress=today]{Auto Progress}{1}{10} \\

    \ganttgroup[progress=45]{Overall}{1}{12}
\end{ganttchart}
```
