Get a msg from a Slider or other Node at startup

Hi All,

First Post.

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.



Hi Peter,

I think you will have to use "persistent context variables" to retrieve the last value.
Inject it into the slider and chart so that it shows the right value from the start.

I'll give it a try soon

Thank you
