Use variable as data in apexcharts

Question

I'm trying to display a chart in apexcharts, and use a variable as the data. When I do this, nothing is displayed. See the following:

var message = '[1,4]'
var options = {
  chart: {
    type: 'line',
    sparkline: {
      enabled: true,
    }
  },
  series: [{
    data: message,
  }],
}   

var chart = new ApexCharts(document.querySelector("#chart"), options);
chart.render();

Using the variable message as data doesn't work. When I switch the line:

data: message,

to

data: [1,4]

it displays correctly. However, I must use a variable. How do I do this?

Answer 1

You declared message variable as STRING, It is expecting an ARRAY

Please change

var message = '[1,4]'

to

var message = [1,4];
