[mapserver-users] dynamic chart CHART_SIZE_RANGE

[Steve.Toutant at inspq.qc.ca]

I thought I could use PROCESSING "CHART_SIZE_RANGE = itemname"
But there is a need to use 
PROCESSING "CHART_SIZE_RANGE = itemname minsize maxsize minval maxval"
But I can't hard code these values in the mapfile cause they can change at 
runtime

I need to set programmatically the minval and maxval . 

How can I do that?
thanks
steve
