after upgrade of ubuntu (maybe 12.04 14.04) saw there difference in python versions. means virtual environments try use old 1 has broken. need recreate of virtual environments, because strange conflicts may happens in standard python libraries.

edit:

if use virtualenvwrapper can type:

rmvirtualenv <envname> mkvirtualenv <envname> -r <path/to/requirement.txt>

this remove , create environment again packages listed in requirements.txt file.

note: if in active environment first deactivate before removing virtual environemnt.

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 .
