Hi members

thanks Norm for your help,..it worked out wonderfully fine

I have been able to query, retrieve and display a postgis layer
and now would like to style it

the classitem is a column containing integer values in the database table
I want to break it up into five equal or natural breaks interval classes
I am able to compute statistics like mean, stdev etc. on the column using PHP

how do I manipulate the layer's classitem containing five classes
I want to access them using the class name
then set the class name to something meaningful like upper/lower
limits of interval
and set the expression for that class

thanks in advance
