Announcing Dash Bio 1.0.0 🎉 : a one-stop-shop for bioinformatics and drug development visualizations.

Can you please explain this error message (TypeError: bar() got an unexpected keyword argument 'text_auto') and how to fix it?

Strangely, I am not finding much information anywhere about this error message. The one response I found proposed upgrading to Plotly 5.5. I re-installed the latest version, which is 5.4…apparently:

"(venv) C:\Users\rober\ings>pip install plotly
Requirement already satisfied: plotly in c:\users\rober\ings\venv\lib\site-packages (5.4.0)
Requirement already satisfied: six in c:\users\rober\ings\venv\lib\site-packages (from plotly) (1.16.0)
Requirement already satisfied: tenacity>=6.2.0 in c:\users\rober\ings\venv\lib\site-packages (from plotly) (8.0.1)"

May I ask, what is going on and how can I fix it?

Here is the full Traceback message:

Traceback (most recent call last):
  File "C:\Users\rober\ings\", line 72, in update_graph
    barchart =, y='Amounts', x='Nutrients', text_auto=True,
TypeError: bar() got an unexpected keyword argument 'text_auto'

Below, I pasted the code I am currently using to produce the figure, which is (more or less) straight from the documentation. If I remove the text_auto argument, it produces the graph without the labels.

Changing the argument to “True” produces the same error message.

Thank you for reviewing my question.

    Output(component_id='the_graph', component_property='figure'),
    [Input(component_id='nutrient_checklist', component_property='value')]
def update_graph(options_chosen):

    dff = df[df['Nutrients'].isin(options_chosen)]
    print (dff['Nutrients'].unique())

    barchart =, y='Amounts', x='Nutrients', text_auto='.2s', title="Controlled text sizes, positions and angles")
    barchart.update_traces(textfont_size=12, textangle=0, textposition="outside", cliponaxis=False)

    return (barchart)
