Yes there is a way to do this. By using the ValueWhen() function you can manipulate the full signal
plot so that only that portion of the plot from the most recent event will display. You may find,
however that it is more useful to start the plot at the second most recent event so that you are
never left with a single bar plot (most recent event occurred on the last bar). When this happens
the plot can be very difficult to see because it is only a small spot.
You can achieve a "trigger" for ValueWhen() by first counting every event. For easiest use it would
probably be helpful if "the event" is restricted to one bar only. By counting these events using
Cum("event") and comparing that against LastValue(Cum("event")) you can create a signal for the
"condition" portion of ValueWhen(). Your code might look something like this.
Condition:="your multiple bar signal"; {signal true for several bars}
Condition:=Condition AND Alert(Condition=0,2); {converted to one bar signal}
Trigger:=LastValue(Cum(Condition)-1)>=Cum(Condition);
ValueWhen(1,Trigger,"support value");
Remove the "-1" from the trigger variable if you really do want to trigger on the last value. You
may also need to change ">=" to "=" or "<=".
If you can't make my suggestion work then ask again. I know the method works but getting the detail
correct can be a little tricky. Any real world example I give is going to need to be adapted before
it will work for you so I have not attempted to provide something you can simply cut and paste.
Think through the issues and ask more questions if it's not clear.
