st: Pie chart problem

[Philip Burgess <philip.burgess.uq@gmail.com>]

I have a problem running a series of pie charts.

Basically, I have a series of charts that vary by only 1 parameter. I
build the chart and then export it .... All of the commands are in one
do file.

The first chart works fine:

graph pie obs3 obs2 if agegrp == 1 & mhsrvset == 1 & collocc == 1, ///
pie(_all, explode) plabel(_all sum, color(white) size(small) format(%6.0f)) ///
by(, title(Pie 1.1.1: Child & Adolescent - Inpatient - Admission)
note(Comparative Data Volume)) ///
scheme(s1color) name(NSW111, replace) by(CR in0510)
graph export "C:\Data\AMHOCN\Data\NOCC\06 Clinical
Ratings\CS\NSW\NSW_PIE_111.emf", replace

But the next in the series fails:

graph pie obs3 obs2 if agegrp == 1 & mhsrvset == 1 & collocc == 2, ///
pie(_all, explode) plabel(_all sum, color(white) size(small) format(%6.0f)) ///
by(, title(Pie 1.1.2: Child & Adolescent - Inpatient - Review)
note(Comparative Data Volume)) ///
scheme(s1color) name(NSW112, replace) by(CR in0510)
graph export "C:\Data\AMHOCN\Data\NOCC\06 Clinical
Ratings\CS\NSW\NSW_PIE_112.emf", replace
The only differences are:

1. the parameter 'collocc' is set to 2 in the second pass;
2. the title changes;
3. the name of the export file changes

I get the following error message:

plabel[1-2+1].style.ref: class type not found
r(4018);

If I rem out the first chart processing, I still get the same error message.

I can't work out what I'm doing wrong.

Any thoughts much appreciated.

Thanks;

Philip
