javascript - Custom colors in C3.js timeseries chart -

i trying set custom colors in c3.js timeseries chart following this example. first element of each array used identify dataset, if have array:

var datatest1 = ['data1', 30, 200, 100, 400, 150, 250]; 

the color property can accessed this:

colors: {data1:'#0000'} 

or:

colors: {'data1':'#0000'} 

however, if use first element of array access them:

var data1id =  datatest1[0]; 

and then:

colors: {data1id:'#0000'} 

it fails. not sure may doing wrong no feedback in browser...

here working example:

var axis = ['x', '2013-01-01', '2013-01-02', '2013-01-03', '2013-01-04', '2013-01-05', '2013-01-06']; var datatest2 = ['data2', 130, 340, 200, 500, 250, 350]; var datatest1 = ['data1', 30, 200, 100, 400, 150, 250];  var data1id =  datatest1[0]; var data2id =  datatest2[0];  var chart = c3.generate({     data: {         x: 'x',         columns: [             axis,             datatest1,             datatest2         ],         colors: {             //data1: '#0000',             //data2: '#0000'             datatest1: '#0000',             datatest2: '#0000'         }     },     axis: {         x: {             type: 'timeseries',             tick: {                 format: '%y-%m-%d'             }         }     } }); 

----- edit doing because data (including identifier) generated dynamically. thanks

you can dynamically create colors object this.

var colors = {}; colors[datatest1[0]] = '#0000'; colors[datatest2[0]] = '#0000'; 

then set in graph this

var chart = c3.generate({     data: {         x: 'x',         columns: [             axis,             datatest1,             datatest2         ],         colors: colors  //set colors object created above     },     axis: {         x: {             type: 'timeseries',             tick: {                 format: '%y-%m-%d'             }         }     } }); 

working code here
