[Tex/LaTex] Gantt chart by pgfgantt 4.0 – problem with tiltes

pgfgantt

I don't know what I am doing wrong. I am trying to customise Gantt chart using pgfgantt package. I have done some research and read the manual but I am completely puzzled by the results. I cannot seem to understand what is actually happening.

I would like to do the following:

  • make the main title centred; sorted, see edit,
  • decrease space between all title,
  • decrease size of first up to third title,
  • increase size of the fourth title (with week dates),
  • and finally rotate labels in the last title so the week in form day/month would fit in cells.

The huge problem is the title spacing and sizing! I tried to read the manual, tried to figure it out by myself but on this stage it is just too complex to understand. I would appreciate any help with that. Thanks

Below is the MWE to show my results on the picture. I use pgfgantt v 4.0 which I believe is not compatible with previous versions.

\ganttset{calendar week text={\small{\startday/\startmonth}}}

\ganttbar{Project X}{2018-09-01}{2018-12-30}
\end{ganttchart}

EDIT.

I found a bug in the code. To centre title I only need to provide a number of all cells in a row:

 \gantttitle{TITLE}{364}

Best Answer

The gap between the title line is determined by y unit title, which is the height of the title plus the gap, and title height, which is the ratio of the first used for the title. E.g. y unit title=1cm and title height=0.75 leads to a 0.25cm heigh gap. Setting title height=1 will therefore remove the gap.

Since the title line for the weeks is higher, it would overlap with the bars. Therefor I added an invisible title line using the option title/.style={opacity=0} to make room for it.

The lables in a title line can be rotated with the option title label node/.append style={rotate=90}.

This results in:
