This is the code that works for me:

CREATE CURSOR TOGRAPH (GRAPH G)
SELECT TOGRAPH
APPEND BLANK
APPEND GENERAL GRAPH CLASS "MsGraph.Chart.8"

CREATE CURSOR runitems (xaxis c(2), yaxis c(10))
INSERT INTO runitems (xaxis, yaxis) values ('1', '100.00')
INSERT INTO runitems (xaxis, yaxis) values ('1', '101.50')
INSERT INTO runitems (xaxis, yaxis) values ('1', '102.50')

WAIT WINDOW 'Generating Graph...' NOWAIT
g_graphdata = "" + CHR(9) + "Set 1" + CHR(13)

GO TOP IN runitems
SELECT runitems
SCAN
g_graphdata = g_graphdata + runitems.xaxis + CHR(9) + runitems.yaxis + CHR(13)
ENDSCAN
APPEND GENERAL TOGRAPH.GRAPH DATA g_graphdata
WAIT CLEAR
