How do you display plots created by the arima library (statsmodels.tsa.arima_model) onto plotly? I tried returning results.plot_predict() in my update_graph function, but I get
InvalidCallbackReturnValue: The callback for [<Output graph.figure>, <Output stage.figure>, <Output discharge.figure>, <Output stage_forecast.figure>] returned a value having typetuple which is not JSON serializable.
Hi @ToastFrench, I’d have to see exactly what the callback is returning to accurately diagnose the problem but basically Dash callbacks can only return strings, numerical arrays, or dictionaries or tuples made up of only strings and/or numerical arrays.
Hi @nickest, thanks for your reply.
This is briefly what my code looks like to return the forecast graph.
model = ARIMA(idf_logscale, order=(1,1,1))
results_ARIMA = model.fit(disp=-1)
forecast = results_ARIMA.plot_predict(1,3000)
return forecast
This is what it looks like if I print it inline
Is it possible to convert into an HTML element somehow?
Ah, the plot it is returning is a matplotlib plot. I’ve never tried, but you can maybe use matplotlylib to convert it to a Plotly figure which would then be compatible with Dash.
