I'm trying to fill a table which has a polygon-type column from another
table with discrete numeric data. It contains circle descriptions by x,y,r
components in seperate columns.
There is a nice polygon() functions which can estimate circles by
polygons. Another one converts a point and radius to a circle
(circle(point, r)). But with which function may i generate a point from
two discrete coordinates? I imaginge something like that:
=polygon( circle( point( oldx, oldy ), radius )
But where is the desired point() function?
Thank you very much!
