Here the "Small" is printed if the radius of Circle 1 is less than or equal to 2.0
and "Big" is printed if it is greater than 2.0.
Use empty quote marks "" to show no output. For example,
If([Circle 1]radius>2.0,"","Small")
gives the same output as
If([Circle 1]radius<=2.0,"Small")
using a slightly different formula.
Min/Max
Use the min and max functions to find the minimum or maximum parameter
for a series of features. For example,
Max(-1,-10,"Diameter")
will produce the maximum diameter of the last 10 circles measured.
