I want to reduce extra space in my chart with customizing minimum range for value axis and as we want to chart seems more natural ;instead of 0 for minmum number we interact it with constant number like 1
min range=min(value field) -(specific number )
the output of min function in jasper is NUMBER
my value field is double
I tried alot for cast and subtract but it doesn't work !
I would appreciate if anybody could help me
thanks in advance
