> Does anybody can show me to plot a regression line from SPSS

Output. Double-click your scatterplot to open the Chart

Editor, then click on Chart-->Options, and check the "Fit

line" box. The default is to fit a least squares regression

line. Other options are also available.

Alternatively, you can use the Interactive Graphics

scatterplot and ask for a regression line:

* GRAPHS-->INTERACTIVE-->SCATTERPLOT .

IGRAPH

/VIEWNAME='Scatterplot'

/X1 = VAR(x) TYPE = SCALE

/Y = VAR(y) TYPE = SCALE

/COORDINATE = VERTICAL

/FITLINE METHOD = REGRESSION LINEAR INTERVAL(95.0) = MEAN

INDIVIDUAL LINE

= TOTAL SPIKE=OFF

/TITLE='Writing Ability' + ' as a Function of Spelling

Competence'

/X1LENGTH = 3.0 /YLENGTH = 3.0

/X2LENGTH = 3.0

/CHARTLOOK = 'Grayscale.clo'

/SCATTER COINCIDENT = NONE.

I normally choose the normal probability plot and the studentised residuals

versus standardised predicted values plot.

The plots are fine apart from one thing - they have these really long titles

in large font across the tops. These titles are integral to the plot, so

when I copy the plot (to paste into Word, for example) the titles come too.

And that's my problem: the titles don't fit properly in the graph picture,

so when I paste I end up missing around half the title (the right hand

side).

Two questions:

1. How do I suppress the titles? The plots are produced from the

regression menu and I can't see a "suppress titles" type option in the

dialog box.

2. If I can't suppress the titles, how do I reduce the font size? Normally

I title the graph in the external package (I give them a figure number, etc)

above the pasted picture, but in documents that are for my own use I

normally forgo that step and I'm happy to use the SPSS-generated title - if

only it would fit!

Help please :-)

cheers
