We’re currently doing the next six months worth of planning here at Linaro. I wanted a simple Gantt chart to show when a task is expected to start and finish and found a nice way of doing it using a LibreOffice stacked bar chart.
The trick is to make the first bar invisible and use it as an offset. Start with a table like this:
|Add support for foo||0||3|
Select all of the data, then select Insert | Chart.... Select ‘Bar’ then the stacked bar chart. Click finish and you’ll see something like this:
Note how the rows are in an unfortunate bottom to top order. Double click on the blue part of any bar to bring up the Data Series dialog. Click on the Area tab, set the Fill to None, and you’ll get this:
You can use extra columns to get extra colours. Here’s the final toolchain timings chart:
