I need help in adding text to my graph.
I have tried text = 'y' and text-position = 'inside' but the text goes vertical or gets squashed for small bar charts so it can fit inside the bar. I just want it to write across.
Here is a working example of the code that needs fixing:
app = dash.Dash(__name__)
app.css.append_css({'external_url': 'https://codepen.io/amyoshino/pen/jzXypZ.css'})
labels1 = ['0-7', '8-12', '13-15', '16-20', '21-25', '26+']
values1 = [10, 30, 10, 5, 6, 8]
labels2 = ['India', 'Scotland', 'Germany', 'NW England', 'N Ireland', 'Norway', 'NE England', 'Paris', 'North Africa', 'scandinavia']
values2 = [1, 0, 4, 9, 11, 18, 50, 7, 0, 2]
values3 = [10, 111, 75, 20]
labels4 = ['Safety Manager', 'Office Administrator', 'Internal Officer', 'Assistant Producer']
bar_color = ['#f6fbfc', '#eef7fa', '#e6f3f7', '#deeff5', '#d6ebf2', '#cde7f0', '#c5e3ed', '#bddfeb', '#b5dbe8', '#add8e6']
bar_color2 = ['#e6f3f7', '#deeff5', '#d6ebf2', '#cde7f0', '#c5e3ed', '#bddfeb', '#b5dbe8', '#add8e6']
app.layout = html.Div([
html.Div([
html.Div([
dcc.Graph(id = 'age',
figure = {
'data': [go.Bar(x = values1,
y = labels1,
orientation = 'h',
marker=dict(color = bar_color2),
text = labels1,
textposition = 'inside'
)
],
'layout': go.Layout(title = 'Number of respondees per tenure',
yaxis=dict(
zeroline=False,
showline=False,
showgrid = False,
autorange="reversed",
),
xaxis=dict(
zeroline=False,
showline=False,
showgrid = False
)
)
}
)
], className = 'four columns'),
html.Div([
dcc.Graph(id = 'location',
figure = {
'data': [go.Bar(x = values2,
y = labels2,
orientation = 'h',
marker=dict(color = bar_color),
text = labels2,
textposition = 'inside'
)
],
'layout': go.Layout(title = 'Number of respondees per region',
yaxis=dict(
zeroline=False,
showline=False,
showgrid = False,
autorange="reversed",
),
xaxis=dict(
zeroline=False,
showline=False,
showgrid = False
) )
}
)
], className = 'four columns'),
html.Div([
dcc.Graph(id = 'job',
figure = {
'data': [go.Bar(x = values3,
y = labels4,
orientation = 'h',
marker=dict(color = bar_color2),
text = labels4,
textposition = 'inside'
)
],
'layout': go.Layout(title = 'Number of respondees per role',
yaxis=dict(
# automargin=True,
zeroline=False,
showline=False,
showgrid = False,
autorange="reversed",
),
xaxis=dict(
zeroline=False,
showline=False,
showgrid = False
)
)
}
)
], className = 'four columns')
], className = 'row')
])
if __name__ == '__main__':
app.run_server()
Here's the output:
Here's an example of how I want my text to look:
I need help with two things:
If you can also give an explanation of how to fix y-axis being cut off in the third chart that would be amazing. For now, I have to change the labels to force it to fit which is time-consuming. Is there a way of adding padding to the container or something?
Thanks.

You can pass text into go.Bar(), where you can set textposition="inside" and insidetextanchor="start", which should solve this issue.
fig = go.Figure(go.Bar(
x=[20, 14, 23],
y=['giraffes', 'orangutans', 'monkeys'],
orientation='h',
# define the annotations
text=['giraffes', 'orangutans', 'monkeys'],
# position, "auto", "inside" or "outside"
textposition="auto",
# anchor could be "start" or "end"
insidetextanchor="start",
insidetextfont=dict(family='Times', size=13, color='white'),
outsidetextfont=dict(family='Times', size=13, color='white')))
fig.update_layout(
yaxis=dict(
showticklabels=False,
))
fig.show()
This is an inelegant workaround, but after scouring the plotly python docs, I couldn't find anything that would do exactly what you were asking with the plotly attributes provided. If you need a one-time, quick fix now, try using yaxis=dict(showticklabels=False) and add your labels manually as annotations like:
layout = go.Layout(
# Hide the y tick labels
yaxis=dict(
showticklabels=False),
annotations=[
dict(
# I had to try different x values to get alignment
x=0.8,
y='giraffes',
xref='x',
yref='y',
text='Giraffes',
font=dict(
family='Arial',
size=24,
color='rgba(255, 255, 255)'
),
align='left',
# Don't show any arrow
showarrow=False,
),
The output I got looked like:
You can check the Plotly Annotations and Chart Attributes documentation to see if there is anything that better suits your needs.
Edit: I started posting this response before the code was added to the question. Here is an example of how the annotations could be made for the first two y labels of the first graph in the code in question:
app.layout = html.Div([
html.Div([
html.Div([
dcc.Graph(id = 'age',
figure = {
'data': [go.Bar(x = values1,
y = labels1,
orientation = 'h',
marker=dict(color = bar_color2),
text = labels1,
textposition = 'inside'
)
],
'layout': go.Layout(title = 'Number of respondees per tenure',
yaxis=dict(
zeroline=False,
showline=False,
showgrid = False,
showticklabels=False
autorange="reversed",
),
xaxis=dict(
zeroline=False,
showline=False,
showgrid = False
)
),
annotations=[dict(
x=0.8,
y=labels1[0],
xref='x',
yref='y',
text=labels1[0],
font=dict(
family='Arial',
size=24,
color='rgba(255, 255, 255)'
),
align='left',
showarrow=False,
),
dict(
x=1.2,
y=labels1[1],
xref='x',
yref='y',
text=labels1[1],
font=dict(
family='Arial',
size=24,
color='rgba(255, 255, 255)'
),
align='left',
showarrow=False,
),
Edit 2: @ user8322222, to answer the question in your comment, you could use a list comprehension to make your annotations dictionary like so:
annotations1 = [dict(x=(len(labels1[i])*0.15), y=labels1[i], xref='x', yref='y',
text=labels1[i], font=dict(family='Arial', size=24, color='rgba(255, 255, 255)'),
align='left', showarrow=False) for i in range(len(labels1))]
However I don't think there will be a constant you could multiply by the length of the text in characters (like I used for x in the example) to get perfect alignment. You could use the pixel length or other measures for the string as in this post to devise a more accurate way of determining x to get it properly aligned. Hope that helps.

You can prevent the y-axis from being cutoff in your third chart by changing the margins of the figure. Add the following code to the inside of the call to go.Layout():
margin=go.layout.Margin(
l=150, # left margin, in px
r=80, # right margin, in px
t=80, # top margin, in px
b=80, # bottom margin, in px
pad=0
)
You can adjust the left margin for different y-axis labels, or you could set it to automatically scale with the length of the longest label.
