javascript - How to Plot x,y coordinates in c3.js chart library? -

-

how can pass x,y values generate chart x values not automatically sorted? if use example x starts on 2 because lowest value. 

var chart = c3.generate({ data: {     x: 'x',     columns: [         ['x', 50, 80, 2,100, 230, 300],         ['data1',400, 200, 100, 50, 25, 12]     ] }

});

if want not sort x values, need treat category axis

var chart = c3.generate({     data: {         columns: [             ['data1',400, 200, 100, 50, 25, 12]         ],         type: "bar",     },     axis: {         x: {             type: 'category',             categories: [50, 80, 2,100, 230, 300],         }     } });
