Thanks much for the reply, Tomasz.
Ton, I think I've generally accomplished what you're inquiring about
with the following:
--------------------------------------------
Resistance = Study("RE", GetChartID());
RECurve = exp(log(Resistance));
// plots conveniently with autoscale; doesn't produce bizarre
vertical scaling
Plot(IIf(NOT Ref(RECurve, -1) < LowestSince(NOT IsNull(Resistance),
L), RECurve, Null), "RECurve", ParamColor("RECurve Color",
colorViolet), styleThick);
--------------------------------------------
I'd still like to plot a curving line on linear charts that
was the equivalent of a ray on a log chart. Any ideas anyone?

this question in a slightly different way. Say I have drawn a
support line on a linear chart. Can I switch to a log chart and get
the same linear support line just by putting an log/exp instruction
before the line ? Giving me the same points where the price touches
the support line ...
