I want to highlight the weekend rows on my gantt chart, but I am not sure how I could do this.

Also I would like to draw a vertical line on every milestone I have.

And is it possible to split the chart on multiple a4 pages?

My current document looks like this:

\documentclass[
    12pt,       % font size
    oneside,    % one-sided pages

            group incomplete/.append style={fill=gray},
            group left shift=0,
            group right shift=0,

            %group progress label font=\bfseries\small,
        ]{18.09.2017}{31.01.2018}

  • I'm fairly certain that it's not possible to break a chart across multiple pages, you're going to have to do it manually I think, i.e. by splitting it into multiple ganttchart environments. Sep 27, 2017 at 9:50

Splitting ganttcharts has to be done manually, as Torbjørn T. already mentioned. Lines for milestones are also not build into pgfgantt. Weekends can be marked with

vgrid={*4{dotted},{red,dotted},dotted,{red,dotted}}

This works for gantt charts starting on Mondays. For other weekdays different patterns have to be used.

But pgfgantt can be expanded to do what you want.

The code below provides the following new options:

  • vgridweek taks two parameters, which are used for the vertical lines. The second is used for the lines between Friday and Saturday and Sunday and Monday. The first is used for all other lines. It will overwrite settings done with vgrid, even if the latter comes after this option. No default.
  • weekend background sets the background color for Saturday and Sunday. If it is set to none the weekends are not colored. Default: weekend background=none.
  • milestone line is a flag. Without parameter of with true milestone lines are drawn. With false lines are not drawn. This option can be given for a whole chart and for individual milestones. It is possible to change this setting locally for a milestone. A milestone line may be overdrawn by the line for today. Default: milestone line=false.
  • milestone line style sets the style for the milestone line. It can only be set for the whole chart, not for individual Milestones. Default: milestone line style/.style={blue,thick}.

The code below patches pgfgantt to get the new code executed at the right time. But this means, the code may not work with older or newer versions of pgfgantt (here the current version was used: 2013/06/01 v4.0).

    Because pgfgantt doesn't play well with babel, you might want to add \usepackage[ngerman]{translator} to the preamble, so that "October" becomes "Oktober".
