Hello all,
When I have a grouped bar chart as shown in the example below, I would like to show the percentage delta between each of the grouped bars as a label. Could anyone point me to documentation or examples that would cover that ?
import plotly.graph_objects as go
animals=['giraffes', 'orangutans', 'monkeys']
fig = go.Figure(data=[
go.Bar(name='SF Zoo', x=animals, y=[20, 14, 23]),
go.Bar(name='LA Zoo', x=animals, y=[12, 18, 29])
])
# Change the bar mode
fig.update_layout(barmode='group')
fig.show()
If I wanted this plot to look like the following, can someone provide an example please ?
looking for a response. bump
@Emmanuelle: In all the documented examples, the user is expected to provide an x coordinate and a y-coordinate. In the case of my example, the x-coordinate doesnβt really hold a continuous value, it is rather a nominal text value. How can I use the annotations example in this case ?
Good question! In fact, there is a mapping between a categorical axis and a continuous one, with the positions of the different categories corresponding to their indices. For example you can do
import plotly.graph_objects as go
animals=['giraffes', 'orangutans', 'monkeys']
fig = go.Figure(data=[
go.Bar(name='SF Zoo', x=animals, y=[20, 14, 23]),
go.Bar(name='LA Zoo', x=animals, y=[12, 18, 29])
])
# Change the bar mode
fig.update_layout(barmode='group')
for i, animal in enumerate(animals):
fig.add_annotation(
go.layout.Annotation(
x=i,
y=5,
text="text")
)
fig.show()
