I am creating a gantt chart in Dash using the built in gantt chart from plotly. I am plotting about 500 bars at a time on the plot and so the y axis label looks awefule. I am also using a ‘callback’ to create my figure. How can I hide the y axis so it doesn’t look so bad?
html.Div([dcc.Dropdown(id = ‘plane-dropdown’,
options=[
{‘label’: ‘F-15 (C model)’, ‘value’: ‘F-15 (C Model)’},
{‘label’: ‘F-15 (E model)’, ‘value’: ‘F-15 (E Model)’},
{‘label’: ‘Global Hawk’, ‘value’: ‘Global Hawk’}
],
value=‘Global Hawk’),
dcc.Graph(id=‘gantt’),#end creation of gantt chart
#adding a range slider below the graph.
dcc.RangeSlider(id=‘gantt_slider’,
marks={i: ‘Year {}’.format(i) for i in range(2016, 2030)},
min=2016,
max=2029,
value=[2018, 2025])
],
)
@app.callback(dash.dependencies.Output(‘gantt’,‘figure’),
[dash.dependencies.Input(‘plane-dropdown’,‘value’),
dash.dependencies.Input(‘gantt_slider’,‘value’)])
def update_graph(selected_dropdown_value,slider_range):
df = dfg[dfg.plane==selected_dropdown_value]
df = df[(df.FY>slider_range[0]) & (df.FY<slider_range[1])]
df = df.reset_index()
del df[‘index’]
return ff.create_gantt(df,index_col=‘Resource’, group_tasks=True,
title =‘Gantt - Time at each gate.’,width=1400,height=600)
