Apex chart x y linear chart based on dateTime



Hey i am using Apex chart with vue.js VueApexChart

Here is my option value :

 export const option = {
    chartOptions: {
        chart: {
            height: 350,
            type: 'line',
            zoom: {
                enabled: false,
            },
            toolbar: {
                show: false,
            },
        },
        dataLabels: {
            enabled: false,
        },
        stroke: {
            curve: 'straight',
        },
        grid: {
            row: {
                colors: ['#f3f3f3', 'transparent'],
                opacity: 0.5,
            },
        },
        yaxis: {
            type: 'numeric',
        },
        xaxis: {
            type: 'datetime',
        },

    },
};

and here in my component data here is my series structure:

chartData = [{
    "name": "Chloride",
    "data": [{
        "x": "2021-02-08",
        "y": 40,
    }]
}, {
    "name": "M Alkalinity",
    "data": []
}]

Then i am having my component called like this:

 <apexchart
    type="line"
    height="350"
    :options="chartOptions"
    :series="chartData"
  />

Nothing is displayed on the chart

Answer

Running it in a codesandbox works fine. Are you sure it isn’t just because you didn’t have any chart data? (I’ve added some in for the example)

See it running here

enter image description here

I changed

chartData = [{
    "name": "Chloride",
    "data": [{
        "x": "2021-02-08",
        "y": 40,
    }]
}, {
    "name": "M Alkalinity",
    "data": []
}]

to:

export default {
  data() {
    return {
      chartOptions: {
        //..
      },
      series: [
        {
          name: "Chloride",
          data: [
            {
              x: "2021-02-08",
              y: 40,
            },
            {
              x: "2021-02-09",
              y: 50,
            },
          ],
        },
        {
          name: "M Alkalinity",
          data: [
            {
              x: "2021-02-08",
              y: 60,
            },
            {
              x: "2021-02-09",
              y: 20,
            },
          ],
        },
      ],
    };
  },
};
