Set plot value from different thread

[ttodua]

I am trying to set PLOT value from Button click.
In "OnButtonClicked" i use:

ChartControl.Dispatcher.InvokeAsync(() =>
{
    // i.e. 5 bars ago from last bar
   Print("start");
    Values[0][5] =123;
   Print("end");
});

However, it is not able to set the value. Instead i get the "Start", but dont get "end" in the output logs.
I probably something stops the whole execution while I try to set plot value from there... any help?

Hello TazoTodua,

Are you getting an indexing error?
(You will need a try and catch and print the exception to find out)

Is there a reason you are invoking into the ChartControl thread? (I don't think you need to be invoking into the UI thread, but if you do, always use InvokeAsync to prevent locking)

If this from a button click event, this would be outside of a data driven method. Is this code within TriggerCustomEvent() to synchronize series?

thanks your examples helped. I don't know what is magic behind TriggerCustomEvent, but it solved problem.
