javascript - Grouped bar chart "in one line" with D3.js -


i'm trying make particular bar chart d3.js, , don't find example match. code bar chart 2 series (one negative, , 1 positive) disposed on same line, not stacked.

i guess maybe it's not clear, i've made on highcharts. want use d3 connect chart map did before.

so, know example me? can sort directly chart if series unordered? , if 2 series punctually postive, little 1 appear in front of largest?

the trick order data, in order so, can use [d3.ascending()][1] functions:

with following example data: 

data = [{     name: "a",     valueright: 1,     valueleft: 2 }, {     name: "b",     valueright: 4,     valueleft: 5 }, ...]

we have: 

function leftbound(node) {     return d3.max([node.valueleft,-node.valueright]) }  function rightbound(node) {     return d3.max([node.valueright,-node.valueleft]) } datasort = function(a,b) {     res = d3.descending(leftbound(a),leftbound(b))     if(res==0) {         return d3.descending(rightbound(a),rightbound(b))     } else {         return res     } }

for reusable charts, can use [selection.sort()][2] have 2 bar categories.

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 .
