actual line graph with fitted trend line

[s_pushparaj]

Dear list
I am running a linear regression for a time series. I wish to draw graph of actual and fitted line graph for the same in one graph. i.e actual line graph with fitted trend line. Kindly help me draw the same.
with thanks

If this is a simple linear regression with one predictor which is just
yourpredvar number, you can use CURVEFIT:

CURVEFIT
  /VARIABLES=yourdepvar
  /CONSTANT
  /MODEL=LINEAR
  /PLOT FIT.

Or you can use GGRAPH to compute and plot the regression:

GGRAPH
  /GRAPHDATASET NAME="graphdataset" VARIABLES=yourpredvar yourdepvar
    MISSING=LISTWISE REPORTMISSING=NO
  /GRAPHSPEC SOURCE=INLINE.
BEGIN GPL
  SOURCE: s=userSource(id("graphdataset"))
  DATA: X=col(source(s), name("yourpredvar"))
  DATA: Y=col(source(s), name("yourdepvar"))
  GUIDE: axis(dim(1), label("yourpredvar"))
  GUIDE: axis(dim(2), label("yourdepvar"))
  ELEMENT: line(position(X*Y), missing.wings(), color("observed"))
  ELEMENT: line(position(smooth.linear(X*Y)), missing.wings(),
color("predicted"))
END GPL.

If you have already used regression and saved the predictor values, you can
also use the GGRAPH command.

GGRAPH
  /GRAPHDATASET NAME="graphdataset" VARIABLES=yourpredvar yourdepvar
predictedvaluevar
    MISSING=LISTWISE REPORTMISSING=NO
  /GRAPHSPEC SOURCE=INLINE.
BEGIN GPL
  SOURCE: s=userSource(id("graphdataset"))
  DATA: yourpredvar=col(source(s), name("yourpredvar"))
  DATA: Y1=col(source(s), name("yourdepvar"))
  DATA: Y2=col(source(s), name("predictedvaluevar"))
  GUIDE: axis(dim(1), label("yourpredvar"))
  GUIDE: axis(dim(2), label("yourpredvar"))
  ELEMENT: line(position(yourpredvar*Y1), missing.wings(),
color("observed"))
  ELEMENT: line(position(yourpredvar*Y2), missing.wings(),
color("predicted"))
END GPL.
