linked list - nested node class operator overload < c++ -


this question has answer here:

i'm trying overload < operator nested node class inside linkedlist class. have setup this: 

linkedlist<t>::node& linkedlist<t>::node::operator<(const linkedlist<t>::node& rhs){     return rhs;  }

but error 1>c:\users\kevin\workspace\linkedlist\linkedlist.h(185): warning c4183: '<': missing return type; assumed member function returning 'int'

i try return 1 doesn't work either.

node dependent name, need use typename tell compiler referring type.

template <typename t> const typename linkedlist<t>::node&  linkedlist<t>::node::operator<(const typename linkedlist<t>::node& rhs)

also, note have const reference, returning non-const one. should return const reference, in real code, confusing operator< not return bool. make more sense:

template <typename t> bool linkedlist<t>::node::operator<(const typename linkedlist<t>::node& rhs) const

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
