There are several solutions depending on how you want to display the graph, and whether you want to do anything else with it.

See if the below is what you need:

clear
CLOSE TABLES all
lnmax=50

CREATE CURSOR inputs (poller C(50),from_date D,to_date D,approve N(3))
FOR ia=1 TO lnmax
	INSERT INTO inputs VALUES (PADL(ia,50,"0"),GOMONTH(DATE(),-1*ia),GOMONTH(DATE(),-1*(ia-1)), 10*ia)
ENDFOR
