Embed Vue component within data section

I am attempting to create a custom tooltip for apexcharts similar to the example shown here: 

tooltip: {
  custom: function({series, seriesIndex, dataPointIndex, w}) {
    return '<div class="arrow_box">' +
      '<span>' + series[seriesIndex][dataPointIndex] + '</span>' +
      '</div>'
  }
}

This setup works fine, but when I try to include a vue component in the return statement, nothing appears.

tooltip: {
  custom: function({series, seriesIndex, dataPointIndex, w}) {
    return '<MyComponent/>'
  }
}

<template>
   <div>Just a simple component</div>
</template>

<script>
export default { name: "MyComponent" }
</script>

What could be causing this issue and how can it be resolved?

Answer №1

In order for Vue to properly render the component, you must instruct it within the custom tooltip function:

tooltip: {
  custom: ({series, seriesIndex, dataPointIndex, w}) => {
    // create component constructor
    var TooltipComponent = Vue.extend({
      template: '<my-component/>'
    });
    // create an instance of tooltip and mount it
    var tooltip = new TooltipComponent();
    tooltip.$mount();
    // Return the html
    return tooltip.$el.outerHTML;
  }
}

If additional data or reactivity is required, the process becomes more complex. Refer to https://v2.vuejs.org/v2/api/#Vue-extend for further details.
