If a user query results in no data, instead of showing the following empty set of axes as pasted below, I’d like to show an error message.
Currently the callback is something like
app.callback(Output('tofu-chart', 'figure'), [Input('page-state', 'children')].Is the only way to do this to make the output of my callback be a Div into which I insert a figure myself?
