[mapserver-users] How to create a chart layer from a php function

[Sandra Liliana Moreno]

Hi!!!!

I want to create a chart layer from a PHP function, but in the style
of the class of the layer,
a parameter called "SIZE" in the mapfile, I do not know how to set in
the object styleObj.
Does anyone know how to do this?
	
Thank.

LAYER
	NAME "Grafica"
	TYPE CHART
	STATUS DEFAULT
	CONNECTIONTYPE POSTGIS
	CONNECTION "host=127.0.0.1 dbname=xxx user=xxx password=xxx port=5432"
	DATA "the_geom FROM (select a.the_geom AS the_geom, a.dpto, a.gid AS
gid, a.nom_dpto,a.area_km2, b.rio, b.queman from departamento a,
dpto_viv_basura b WHERE a.dpto = b.dpto) AS foo USING UNIQUE gid"
	PROCESSING "CHART_TYPE=pie"
	PROCESSING "CHART_SIZE=30"
	CLASS
		NAME "Rio"
		STYLE
			SIZE [rio]
			COLOR 255 244 237
		END
	END
	CLASS
		NAME "Queman"
		STYLE
			SIZE [queman]
			COLOR 255 217 191

	END
END #LAYER
