Annotations issues on distplots with plotly 3.1.0

[rbgt]

Hello, I've had a new computer at work so I had to reinstall all packages and so on to get plotly and re-use my work I've done before,

I just noticed that when I wanted to add 1 notation, it did work, but when I wanted to add multiple notations (2 in my case), it didn't appear at all.

Here is how I did code in python 3:

fig_var=ff.create_distplot(data_var,labels,bin_size=0.00005,curve_type="normal",show_hist=True,show_rug=False)
fig_var['layout'].update(title='Distribution of potential loss/returns',
                         titlefont=dict(color='#FFF'),
                         legend=dict(
                                     font=dict(color='#FFF')),
                         plot_bgcolor='#000000',
                         paper_bgcolor='#000000',
                         xaxis=dict(title='Loss -- Returns (%)',
                                  titlefont=dict(color='#5998ff'),
                                  mirror='ticks',
                                  linecolor='#5998ff',
                                  linewidth=3,
                                  tickfont=dict(
                                                family='Old Standard TT, serif',
                                                color='white')
                                  ),
                         yaxis=dict(title='Number of minutes',
                                  titlefont=dict(color='#5998ff'),
                                  mirror='ticks',
                                  linecolor='#5998ff',
                                  linewidth=3,
                                  showticklabels=False
                                  ),
                         annotations=[
                                     dict(
                                          x=VaR_95,
                                          y=0,
                                          xref='x',
                                          yref='y',
                                          text='VaR 95',
                                          font=dict(color='#F00'),
                                          showarrow=True,
                                          arrowhead=7,
                                          ax=0,
                                          ay=-350,
                                          arrowcolor='#F00'
                                          ),
                                     dict(
                                          x=CVaR_95,
                                          y=0,
                                          xref='x',
                                          yref='y',
                                          text='Expected Shorfall',
                                          font=dict(color='#F00'),
                                          showarrow=True,
                                          arrowhead=7,
                                          ax=0,
                                          ay=-300,
                                          arrowcolor='#F00'
                                          )
                                 ]
                        )

in version 3.1.0, it didn't show any annotations and didn't mirror my blue lineborder either
whereas in version 2.7.0, it worked perfectly as expected.

Here is what I expect and working in plotly 2.7.0 :

and here is the version 3.1.0 :

Does any of you has had an annotation issue related just like I did ? For another scatter plot, annotation worked but it seems not working for distplot here

Question: is there anything changed about annotations in the new version 3 plotly ?

NB: I didn't change the code in between the 2 versions, it was exactly the same.

Thank you for reading

Hi @rickantonais , Thanks for taking the time to let us know. I believe this is a duplicate of #1072. In version 3 there's a problem using .update to initialize an array property (like layout.annotations).

Until a fix is out you can use property assignment to update the annotations. For example:

fig_var=ff.create_distplot(data_var,labels,bin_size=0.00005,curve_type="normal",show_hist=True,show_rug=False)
fig_var['layout'].update(title='Distribution of potential loss/returns',
                         titlefont=dict(color='#FFF'),
                         legend=dict(
                                     font=dict(color='#FFF')),
                         plot_bgcolor='#000000',
                         paper_bgcolor='#000000',
                         xaxis=dict(title='Loss -- Returns (%)',
                                  titlefont=dict(color='#5998ff'),
                                  mirror='ticks',
                                  linecolor='#5998ff',
                                  linewidth=3,
                                  tickfont=dict(
                                                family='Old Standard TT, serif',
                                                color='white')
                                  ),
                         yaxis=dict(title='Number of minutes',
                                  titlefont=dict(color='#5998ff'),
                                  mirror='ticks',
                                  linecolor='#5998ff',
                                  linewidth=3,
                                  showticklabels=False
                                  )
                        )

fig_var.layout.annotations=[
                                     dict(
                                          x=VaR_95,
                                          y=0,
                                          xref='x',
                                          yref='y',
                                          text='VaR 95',
                                          font=dict(color='#F00'),
                                          showarrow=True,
                                          arrowhead=7,
                                          ax=0,
                                          ay=-350,
                                          arrowcolor='#F00'
                                          ),
                                     dict(
                                          x=CVaR_95,
                                          y=0,
                                          xref='x',
                                          yref='y',
                                          text='Expected Shorfall',
                                          font=dict(color='#F00'),
                                          showarrow=True,
                                          arrowhead=7,
                                          ax=0,
                                          ay=-300,
                                          arrowcolor='#F00'
                                          )
                                 ]

Or you can downgrade back to version 2.7 and wait until a fix for #1072 is released (probably a couple of weeks).

Thanks!

Hi, I am seeing this exact issue in plotly==4.5.0 and in 4.11. Any idea on when this will be fixed?
