Overlapping tasks in discontinuous gantt chart


#1

Hi,

Thanks for the task grouping functionality @spextrow and @jack.

We are wondering if there is any feature available, that can help when grouped tasks overlap, i.e.

Blockquote
import plotly.plotly as py
import plotly.figure_factory as ff

df = [dict(Task="Job-1", Start='2017-01-01', Finish='2017-02-02', Resource='Complete'),
  dict(Task="Job-1", Start='2017-01-15', Finish='2017-03-15', Resource='Incomplete'),
  dict(Task="Job-2", Start='2017-01-17', Finish='2017-02-17', Resource='Not Started'),
  dict(Task="Job-2", Start='2017-01-17', Finish='2017-02-17', Resource='Complete'),
  dict(Task="Job-3", Start='2017-03-10', Finish='2017-03-20', Resource='Not Started'),
  dict(Task="Job-3", Start='2017-04-01', Finish='2017-04-20', Resource='Not Started'),
  dict(Task="Job-3", Start='2017-05-18', Finish='2017-06-18', Resource='Not Started'),
  dict(Task="Job-4", Start='2017-01-14', Finish='2017-03-14', Resource='Complete')]

colors = {'Not Started': 'rgb(220, 0, 0)',
      'Incomplete': (1, 0.9, 0.16),
      'Complete': 'rgb(0, 255, 100)'}

fig = ff.create_gantt(df, colors=colors, index_col='Resource', show_colorbar=True, group_tasks=True)
py.iplot(fig, filename='gantt-group-tasks-together', world_readable=True)

Note that Job-1 overlaps and cannot determine where the first task of job-1 really ends. Could dotted lines or a unfilled rectangle be used?
