graph - ISO C++ forbids intilization of member maxY -
that's code using graphs in arduino i'm getting error saying iso c++ forbids intilization of member maxy. can know why?
class graph { float maxy = 0; float maxx = 0; int maxi = 0; boolean dot=true; boolean rightaxis; boolean errorflag=false; boolean showmouselines=true;
because c++ forbids initialisation of instance members in-line that.
you should initialise them in constructor or, if they're meant class variables (one shared across all instances) rather instance variables, make them static.
