ChartJS not rendering lines according to x-axis data

February 20, 2023

Data:

const data={
  "labels": [
    0,  
    400,
      800,
      1200,
      1600,
      2000,
      2400,
      2800,
      3200,
      3600,
      4000
  ],
  "datasets": [
    {
      "axis": 'x',
      "label": "FFF",
      "borderColor": "Red",
      "backgroundColor": "Red",
      "data": [
          {
              "x": 2883,
              "y": 129
          },
          {
              "x": 3509,
              "y": 118
          },
          {
              "x": 3916,
              "y": 73
          }
      ]
  }
  ]
};

Chart:

I am providing both x & y axis values, the result should be like this for red line.
But for current config it rendering the line from start instead of specific point on x-axis.

>Solution :

You have to use scatter chart and showline : true option instead of line chart for this result.

//your code

const data={
  "labels": [
    0,  
    400,
      800,
      1200,
      1600,
      2000,
      2400,
      2800,
      3200,
      3600,
      4000
  ],
  "datasets": [
    {
      "axis": 'x',
      "label": "FFF",
      "borderColor": "Red",
      "backgroundColor": "Red",
      "showLine": true,         //add this option to connect dots of scatterred points
      "data": [
          {
              "x": 2883,
              "y": 129
          },
          {
              "x": 3509,
              "y": 118
          },
          {
              "x": 3916,
              "y": 73
          }
      ]
  }
  ]
};

<Scatter data={data} />
