javascript - Data not showing up in Google Chart -


i've looked @ every thread find on how json feed google chart, nothing seems working or threads different problem.

update: i'm trying parse json feed show columns. example, feed has actual , goal column. want chart show actual column. need goal column filtering reasons on end, when feed updates database knows records pull.

after following json format google charts , figuring out way add data, i'm still unsuccessful in getting actual data show up. what's weird graph shows up, doesn't have data in it. no errors in console.i've made sure json string valid, is. i've tried logging json feed make sure information being passed correctly , is. columns added, in code, rows won't show up.

i believe in data.addrow line, i'm not traversing correctly, can't seem figure out how correctly down specific cell. 

function drawchart() {       $.ajax({       url: "--",       datatype:"json",       success: function (result) {         var data = new google.visualization.datatable();         data.addcolumn('string', 'quarter');          data.addcolumn('number', 'actual');           (var = 0; < result.rows.length; i++) {           data.addrow([result.rows[i], result.rows[i], result.rows[i]]);         }

here json feed: 

{ "cols":[ {"label":"quarter", "type":"string"},{"label": "actual", "type":"number"}, {"label":"goal","type":"number"}], "rows":[ {"c":[{"v":"q1"}, {"v":22}, {"v":30}]},   {"c":[{"v":"q2"}, {"v":24}, {"v":30}]},   {"c":[{"v":"q3"}, {"v":27}, {"v":30}]}  ]}

you build datatable raw json:

var data = new google.visualization.datatable(json);

and use dataview filter out "goal" column:

var view = new google.visualization.dataview(data); view.setcolumns([0, 1]);

draw chart using dataview instead of datatable:

chart.draw(view, options);

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 .
