Hi group,

I have data admission tools data and various GPAs for

classes from 1991 to 1999, and I have used the following

syntax to produce a scatterplot for each year with X = an

admission tool, and Y = one of the GPAs.

IGRAPH

/VIEWNAME='Scatterplot'

/X1 = VAR(x) TYPE = SCALE

/Y = VAR(y1) TYPE = SCALE

/PANEL = VAR(cyoat)

/COORDINATE = VERTICAL

/FITLINE METHOD = REGRESSION LINEAR LINE = TOTAL SPIKE=OFF

/X1LENGTH=3.0

/YLENGTH=3.0

/X2LENGTH=3.0

/CHARTLOOK='NONE'

/SCATTER COINCIDENT = NONE.

This produces a 3x3 grid of scatterplots, one scatterplot

for each year. It also plots a regression line on each one,

and has two lines of text giving the regression equation and

the R-squared value. As far as I can tell, I cannot plot

the line without the 2 lines of text. And the problem is

that the two lines of text are situated on top of the cloud

of points, just below the regression line, and are very

difficult to read. I know how to move them around (or

delete them) manually, but this soon becomes very tedious,

given the number of charts.

I was hoping that I could make the changes on one chart,

then save a ChartLook to apply when making subsequent

charts. But the changes I want to make are not among the

properties that can be controlled with a ChartLook, apparently.

So, the question is: Does anyone have any ideas about how

to automatically remove (or move) the two lines of text

giving the regression equation and R-squared values? Does

anyone have a script, for example?

Cheers,

Bruce
