[FIXED] Recent Plotly Update [?] - bugs now showing in plots

Bug Reports
1

Just wondering if there has been an Anvil / plotly update as the plots that I draw on a regular basis now have some irregularities. I normally draw using plotly express.timeline but the images now show up with odd shapes. For example the traces are now odd shaped - previously all trace heights were the same - single line sized.

Black rectangles added to mask data only and not part of the issue.

Code to create the plots:

df = pd.DataFrame(list_of_dicts)

    fig = px.timeline(df,
                      x_start="Start",
                      x_end="Finish",
                      y="ID",
                      color="Status",
                      color_discrete_map = colours,
                      text = 'Client',
                      template = "simple_white",
                      height = 150 + (df['ID'].nunique()*35),
                     )

Happy to provide a clone to Anvil.

UPDATE: I have tried rolling back the version to earlier this month when I am confident this issue wasn’t present but the issue persists,

Hi @rickhurlbatt

There haven’t been any recent updates to Anvil or Plotly, but we can certainly help you get to the bottom of this. Please can you share a clone link here to a minimal example? The app you shared with us privately has dependencies, and is quite large.

Thanks!

Hi @rickhurlbatt

After further investigation, this turned out to be a bug in the Plotly client library! Updating Anvil to use the very latest version seems to have fixed the issue - please can you verify that it’s now working for you?

Thanks Ian. I can confirm this has resolved it.
Many thanks for the quick support!
