I want to put a smooth line through a de-seasonalized time series
that shows a trend and residual variability. I'm having trouble
adjusting the tension of the smooth which I think needs to be less
than one. I would like the overlaid smooth curve to be much more
smooth than the data, but I'm basically getting a high order
polynomial smooth at present. <br>
<br>
Here is a snip of code:<br>
<br>
(Note: the xyplot tsplots(2) was previously defined)<br>
<br>
xi = (/spice_ts_ss&time/)<br>
yi = monthly_anom(:,0,0)<br>
xo = fspan(1985., 2015., 200)<br>
ftsetp("sig",0.5)<br>
yo = ftcurv(xi,yi,xo)<br>
<br>
colors = (/"red","green","blue"/)<br>
resplot@xyLineColor = colors(0)<br>
tsplots(3) = gsn_csm_xy (wks,xo,yo,resplot)<br>
overlay(tsplots(2), tsplots(3))<br>
<br>
Changing the value of the sig parameter in ftsetp between 0.1 to 40
seems to have no effect, which suggests that I am misusing
something?<br>
<br>
Thanks in advance,<br>
