I am creating a flow with a slider and a chart. I am also using a trigger to keep the chart flowing with the last msg. All good.
However At startup there is no msg for the trigger to send and so the chart does not start when I start the flow.
I have tried a few things like the Inject but that just sends a value through and does not give the slider a "read" or a value for it's msg.
I suspect this is the same for some other nodes.
