javascript - C3 bar chart unknown number of bars -



javascript - C3 bar chart unknown number of bars -

i using c3.js create bar chart.

my case such:

i want collect x number of info , display them in chart have created next script:

$.ajax({ type: 'post', url: '/academystat/academy_module_user_report', datatype: 'json', data: { request: 'ajax', team_id: team_id, module_id: module_id }, success: function (data) { if(data != null) { (var = 0; < data.length; i++) { var add_data = [data[i]['name'], data[i]['score']] char_data.push(add_data); } var chart = c3.generate({ bindto: '#score_chart', data: { columns: [ char_data ], type: 'bar' } }); } } });

as can see above illustration looping through info , adding array untill have array of array's (unknown number of data).

however when run in browser next error in console:

error: invalid value <path> attribute d="m 286.6,nan l286.6,nan l531.4,nan l531.4,nan z" d3.min.js:5 error: invalid value <path> attribute d="m 1102.6,nan l1102.6,nan l1347.3999999999999,nan l1347.3999999999999,nan z" d3.min.js:5 error: invalid value <path> attribute d="m 286.6,nan l286.6,nan l531.4,nan l531.4,nan z" d3.min.js:5 error: invalid value <path> attribute d="m 1102.6,nan l1102.6,nan l1347.3999999999999,nan l1347.3999999999999,nan z" d3.min.js:5 error: invalid value <path> attribute d="m 286.6,nan l286.6,nan l531.4,nan l531.4,nan z" d3.min.js:5 error: invalid value <path> attribute d="m 1102.6,nan l1102.6,nan l1347.3999999999999,nan l1347.3999999999999,nan z" d3.min.js:5 error: invalid value <path> attribute d="m 286.6,nan l286.6,nan l531.4,nan l531.4,nan z" d3.min.js:5 error: invalid value <path> attribute d="m 1102.6,nan l1102.6,nan l1347.3999999999999,nan l1347.3999999999999,nan z" d3.min.js:5 error: invalid value <path> attribute d="m 286.6,nan l286.6,nan l531.4,nan l531.4,nan z" d3.min.js:5 error: invalid value <path> attribute d="m 1102.6,nan l1102.6,nan l1347.3999999999999,nan l1347.3999999999999,nan z" d3.min.js:5 error: invalid value <path> attribute d="m 286.6,nan l286.6,nan l531.4,nan l531.4,nan z" d3.min.js:5 error: invalid value <path> attribute d="m 1102.6,nan l1102.6,nan l1347.3999999999999,nan l1347.3999999999999,nan z" d3.min.js:5 error: invalid value <path> attribute d="m 286.6,nan l286.6,nan l531.4,nan l531.4,nan z" d3.min.js:5 error: invalid value <path> attribute d="m 1102.6,nan l1102.6,nan l1347.3999999999999,nan l1347.3999999999999,nan z" d3.min.js:5 error: invalid value <path> attribute d="m 286.6,nan l286.6,nan l531.4,nan l531.4,nan z" d3.min.js:5 error: invalid value <path> attribute d="m 1102.6,nan l1102.6,nan l1347.3999999999999,nan l1347.3999999999999,nan z" d3.min.js:5 error: invalid value <path> attribute d="m 286.6,nan l286.6,nan l531.4,nan l531.4,nan z" d3.min.js:5 error: invalid value <path> attribute d="m 1102.6,nan l1102.6,nan l1347.3999999999999,nan l1347.3999999999999,nan z" d3.min.js:5 error: invalid value <path> attribute d="m 286.6,nan l286.6,nan l531.4,nan l531.4,nan z" d3.min.js:5 error: invalid value <path> attribute d="m 1102.6,nan l1102.6,nan l1347.3999999999999,nan l1347.3999999999999,nan z" d3.min.js:5 error: invalid value <path> attribute d="m 286.6,nan l286.6,nan l531.4,nan l531.4,nan z" d3.min.js:5 error: invalid value <path> attribute d="m 1102.6,nan l1102.6,nan l1347.3999999999999,nan l1347.3999999999999,nan z

however if instead utilize method pop info displayed fine. problem pop(); have know how many arrays char_data array has , impossible me know.

has tried similar or know how might prepare issue?

it looks setting charts columns array within array columns: [ [ ['name', 'score'] ] ]

change columns: [ char_data ] columns: char_data

$.ajax({ type: 'post', url: '/academystat/academy_module_user_report', datatype: 'json', data: { request: 'ajax', team_id: team_id, module_id: module_id }, success: function (data) { if (data != null) { (var = 0; < data.length; i++) { var add_data = [data[i]['name'], data[i]['score']] char_data.push(add_data); } var chart = c3.generate({ bindto: '#score_chart', data: { columns: char_data, type: 'bar' } }); } } });

javascript arrays c3.js
