rangeslider template bug (non-attribute inserted into layout instead of fullLayout) #6310
Description
When you add a rangeslider, its yaxis container gets _template: null inserted into the input (layout) object. This isn't an attribute, so it should only be inserted in the fullLayout object, not the layout object.

This doesn't cause problems directly in plotly.js, but it should be fixed here because it can cause problems in Dash if you reload a figure into Python after displaying it on the page, for example:
from dash import Dash, dcc, html, callback, Input, Output, State
import random
import datetime
import plotly.graph_objects as go
app = Dash(__name__)
app.layout = html.Div([
html.Div(style={'display': 'flex'}, children=[
dcc.Graph(
id='graph-ph',
figure={
'data': [
{'x': [],
'y': [0, random.random()],
'mode':'lines+markers',
}],
'layout': {
'title': 'pH (pH)'
}},
),
]),
dcc.Interval(
id='interval-graph-update',
interval=3000,
max_intervals=3),
])
@callback(
Output('graph-ph', 'figure'),
Input('interval-graph-update', 'n_intervals'),
State('graph-ph', 'figure')
)
def update_extend_traces_traceselect(n_intervals, fig_raw):
x_new = datetime.datetime.now()
y_new = random.random()
fig_raw['data'][0]['x'] = fig_raw['data'][0]['x'] + [x_new]
fig_raw['data'][0]['y'] = fig_raw['data'][0]['y'] + [y_new]
fig = go.Figure(fig_raw)
fig.update_xaxes(rangeslider={'visible': True})
return fig
if __name__ == '__main__':
app.run_server(debug=True)Which gives the error (from the line fig = go.Figure(fig_raw) on the second callback call):
ValueError: Invalid property specified for object of type
plotly.graph_objs.layout.xaxis.rangeslider.YAxis: '_template'
Until this is fixed, removing the problematic container (you could even remove just _template) can avoid the error:
# add these lines before fig = go.Figure(fig_raw)
if 'rangeslider' in fig_raw['layout']['xaxis']:
del fig_raw['layout']['xaxis']['rangeslider']['yaxis']Reacted by dserero, ssg-data, Lucas W. and Sean Reed

very helpful tip above about deleting the problematic piece before go.Figure(fig_raw).
