Issue With Plotly

Anvil Q&A
1

Hi,

Seems like Anvil is having some issues. Running existing code that worked fine two weeks back. Should draw Plotly gauges. Today it is displaying graphs: -

It is happening to all my projects using Plotly gauges

Code Sample:

  #lets build the form plots
  flo_grade = lis_dic_updated_kpis[0][str_return_list_key]
  write_log_msg(str_func_name=update_kpi_elements.__name__, str_state='executing', str_type='DEBUG', str_message=f'flo_grade=({flo_grade}), lis_dic_updated_kpis[0][\'flo_grade\']=({lis_dic_updated_kpis[0][\'flo_grade\']})')
  obj_gauge = plotly_graph.Figure(plotly_graph.Indicator(mode="gauge+number", 
                                                         value=flo_grade,
                                                         gauge={'axis': {'range': [None, 100]}, 
                                                                'bar': {'color': "black"},
                                                                'steps': [{'range': [0, 30], 'color': "red"}, {'range': [80, 100], 'color': "gold"}],

  obj_kpis_form.plot_HaiderLatest.data = obj_gauge

Thanks for reporting. We’ll look into it.

Could you change your code to


obj_gauge_faz = go.Indicator(...) # no use of go.Figure
obj_kpis_form.plot_FazLatest.data = obj_gauge_faz

Or Alternatively


obj_gauge_faz = go.Figure(go.Indicator(...)) # as you have currently
obj_kpis_form.plot_FazLatest.figure = obj_gauge_faz
4

obj_kpis_form.plot_FazLatest.figure = obj_gauge_faz

.figure instead .data worked but wondering what has changed? I have other projects that used .data and worked previously. It’ something that’s happened in the past two weeks.

It looks like you found a way around an internal bug.
Setting the .data property to a go.Figure object should never have worked.
The .data property is for the plot data (in your case the go.Indicator() instance)

The specific bug was handling the first argument to go.Figure correctly (which it now does).

If you’re original code had have looked like:

obj_kpis_form.plot_FazLatest.data = go.Figure(data=go.Indicator(...))

Then the code wouldn’t have worked (as expected) and setting the .figure property would have been the right approach.

Sorry your code managed to get caught in the cross fire here.

Was a patch rolled out that fixed the bug and caused the code to stop working. The idea in the long run is to use Anvil for a tool which other companies will use. If Anvil is to be patched we’d like to know before-hand so we can arrange regression testing to confirm the application still works as expected.
