Hi Andrew
I don't believe it's possible to extend the existing plot (CMAP) into the N/A
region at the right side of the chart. I think what you need to do is create a
supplementary plot that begins from the last visible bar of CMAP. How you
define the values for this plot is up to you - there are a number of ways you
could go. Here's some code that you can add onto your existing indicator to
enable a plot of some sort.
D:=IsDefined(CMAP) AND IsDefined(Ref(CMAP,1))=0;
ValueWhen(1,D,LastValue(CMAP));
This is only useful visually - it can't be applied easily to explorations or system
tests. That's not to say that you can't use the same method to evolve a final
plot to include both the original and any extension you come up with. However
I fear that the limited functionality of IsDefined() may be the obstacle that you
can't get over.
Kind regards
Roy
