3.5.0 displays raw title dict in online plot.ly figure tab titles

[zig1000]

May not be a bug you control, but hopefully you can pull some strings...
In Plotly 3.5.0, when a figure is published online to https://plot.ly/, the tab title (which used to say e.g. Title Text | Scatter Chart made by...) now shows the new layout title dict in place of Title Text (e.g. { 'text': '...', 'font':16} | Chart made by ...}).
Tested in Chrome. Not an issue as of at least plotly 3.4.1.

Don't want to advertise the live example, but something like this code should reproduce it:

import plotly
import plotly.graph_objs as go

dummy_trace = go.Scatter(x=[], y=[],
    hoverinfo='none',
    showlegend=False,
    mode='markers',
    marker=dict(
        color=[],
        size=5,
        line=dict(width=1)))

fig_layout = go.Layout(
    title='<br><b>Plotly 3.5.0 Test</b>', # This
    titlefont=dict(size=16),              # and this, show up as json in the plot.ly tab title
    showlegend=True,
    legend=dict(x=0.9, y=0.95),
    hovermode='closest',
    dragmode='pan',
    margin=dict(b=5, l=5, r=5, t=40, pad=0),
    annotations=[ dict(
        text="(not relevant to the bug)",
        showarrow=False,
        xref="paper", yref="paper",
        x=1.0, y=1.0) ],
    xaxis=dict(showgrid=False, zeroline=False, showticklabels=False),
    yaxis=dict(showgrid=False, zeroline=False, showticklabels=False,
               scaleanchor='x', scaleratio=1, range=[-0.05, 1.05]))
                   
fig = go.Figure(data=[dummy_trace], # Obfuscated data since probably not relevant to the bug
                layout=fig_layout)
                   
plotly.plotly.plot(fig, filename='Plotly_3_5_0_bug', sharing='public')

Also while I'm here I thought I'd ask if you know of ways to do / whether there's anything in the pipeline for a couple of small wants:

• left-aligning hover text, as discussed here: Text align when hover on scatterplot plotly.js#260 , since any multi-line hover boxes that appear left of a data point have very ugly text as a result.

• A python-side way to prevent a trace from being hidden when other traces are double-clicked in the legend

Hi @zig1000,

Thanks for taking the time to report this. I've passed it along to the folks that work on the web interface.

Also while I'm here I thought I'd ask if you know of ways to do / whether there's anything in the pipeline for a couple of small wants:

left-aligning hover text, as discussed here: plotly/plotly.js#260 , since any multi-line hover boxes that appear left of a data point have very ugly text as a result.

plotly/plotly.js#260 is where this would need to happen, so +1 the issue if you haven't already 🙂

A python-side way to prevent a trace from being hidden when other traces are double-clicked in the legend

Could you open a new issue on this? It would be possible to expose the legend click events (https://plot.ly/javascript/plotlyjs-events/#legend-click-events) to Python when using the FigureWidget. But I'm not sure what we could do for the non-FigureWidget case.

Closing as this has been fixed in chart studio. Thanks again for letting us know!
