Hello,
Is it possible to do this type of chart?

There's nothing built in that will do it. You can do it with some trickery though. See below:
Code: Select all
create a 1970 2002
series NewZealand = rnd
series Australia = rnd
series Canada = rnd
series uk = rnd
'use 1989 as the base year
series Can1989 = canada
series Aus1989 = australia
series NZ1988 = newzealand(-1)
series nz1996 = newzealand(+7)
series uk1980 = uk(-9)
group g can1989 aus1989 nz1988 nz1996 uk1980
smpl 1983 1995
freeze(gr) g.line
alpha obslab = @str(@year-1989)
gr.setobslabel(series) obslab
show gr

But there should be a way to do this. Wanting to show before vs after "event" data is pretty common.

I am almost sure that the following chart is not possible to do without manual fiddling of the date axis with addtext(s) (as I was doing with the chart types above before Gareth's stunned me with his super simple solution). It could be great if these types of double date axis charts were built into future Eviews versions.

Yeah, I can't think of another way to get that double scale. If we allowed carriage returns in obs labeling, it would be easy, but we don't :(
