My chart lines are not in order

问题

I have a graph and the result of joining all the lines should be as in the image. but currently they are not. what am I doing wrong?

https://jsfiddle.net/r2uaq27a/

var chart = c3.generate({
  data: {
    xs: {
      data1: "data2"
    },
    columns: [
      ['data1', 2,3,4,7,8,9,8,7,3],
      ['data2', 1,2,3,4,5,4,3,2,1]
    ]

  }
});

回答1:

Set the some what undocumented xSort property of data to false:

var chart = c3.generate({
    data: {
        xSort: false,
        x: 'x',
        order: function (i) { console.log(i); },
        columns: [
            ['x', 1,2,3,4,5,4,3,2,1],
            ['data1', 2,3,4,7,8,9,8,7,3]
        ]
    }
});

Running:

var chart = c3.generate({
  data: {
    xs: {
      data1: "data2",
      data3: "data4"
    },
    xSort: false,
    columns: [
      ['data1', 2,3,4,7,8,9,8,7,3],
      ['data2', 1,2,3,4,5,4,3,2,1],
      ['data3', Math.random() * 10,Math.random() * 10,Math.random() * 10,Math.random() * 10,Math.random() * 10,Math.random() * 10],
      ['data4', Math.random() * 10,Math.random() * 10,Math.random() * 10,Math.random() * 10,Math.random() * 10,Math.random() * 10]
    ]

  }
});

#catImage {
  width: 40px;
  height: 40px;
  position: absolute;
  left: 40px;
  top: 0px;
}
