I am kinda new to LaTeX. I wanted to implement a Gantt chart that corresponds to years 2012 - 2019.

I looked for references at this code that uses tikz, manage to configure it pretty much as I needed, but couldn't change the "months" (1,2,3..15) to the years I needed.

Snippet:

documentclass{article}

usepackage[a4paper,landscape,margin=3cm]{geometry}

usepackage{tikz}

usetikzlibrary{calc}



% GanttHeader setups some parameters for the rest of the diagram

% #1 Width of the diagram

% #2 Width of the space reserved for task numbers

% #3 Width of the space reserved for task names

% #4 Number of months in the diagram

% In addition to these parameters, the layout of the diagram is influenced

% by keys defined below, such as y, which changes the vertical scale

defGanttHeader#1#2#3#4{%

 pgfmathparse{(#1-#2-#3)/#4}

 tikzset{y=7mm, task number/.style={left, font=bfseries},

     task description/.style={text width=#3,  right, draw=none,

           font=sffamily, xshift=#2,

           minimum height=2em},

     gantt bar/.style={draw=black, fill=blue!30},

     help lines/.style={draw=black!30, dashed},

     x=pgfmathresult pt

     }

  deftotalmonths{#4}

  node (Header) [task description] at (0,0) {textbf{large Task Description}};

  begin{scope}[shift=($(Header.south east)$)]

    foreach x in {1,...,#4}

      node[above] at (x,0) {footnotesizex};

 end{scope}

}



% This macro adds a task to the diagram

% #1 Number of the task

% #2 Task's name

% #3 Starting date of the task (month's number, can be non-integer)

% #4 Task's duration in months (can be non-integer)

defTask#1#2#3#4{%

node[task number] at ($(Header.west) + (0, -#1)$) {#1};

node[task description] at (0,-#1) {#2};

begin{scope}[shift=($(Header.south east)$)]

  draw (0,-#1) rectangle +(totalmonths, 1);

  foreach x in {1,...,totalmonths}

    draw[help lines] (x,-#1) -- +(0,1);

  filldraw[gantt bar] ($(#3, -#1+0.2)$) rectangle +(#4,0.6);

end{scope}

}



% Example

  GanttHeader{.8textwidth}{2ex}{4cm}{15}

  Task{1}{Requirement analysis}{0}{3}

  Task{2}{Devise an abstract}{0.5}{1}

I agree with Alan Munn that you will be much better off if you use pgfgantt. Just in case we can't convince you, you may try

usepackage[a4paper,landscape,margin=3cm]{geometry}

usepackage{tikz}

usetikzlibrary{calc}



% GanttHeader setups some parameters for the rest of the diagram

% In addition to these parameters, the layout of the diagram is influenced

% by keys defined below, such as y, which changes the vertical scale
