Meteor ApexCharts

This packages wraps ApexCharts NPM package in a meteor package. It provides a template that embeds one ApexChart.

This package is unofficial and it's not supported by ApexCharts team. Any bugs within the ApexCharts library itself must be posted in its official github repo. I'll try to keep npm dependency version up to date, but feel free to PR version updates if you test it before.

Install

As simple as any other meteor package:

meteor add luixal:meteor-apexcharts

Usage

Just include the template in your html:

{{> apexChart options}}

and provide options form a helper:

Template.myTemplate.helpers({
  options() {
    return {
      options: {
            chart: {
                height: 350,
                type: 'bar',
            },
            plotOptions: {
                bar: {
                    horizontal: false,
                    endingShape: 'rounded',
                    columnWidth: '55%',
                },
            },
            dataLabels: {
                enabled: false
            },
            stroke: {
                show: true,
                width: 2,
                colors: ['transparent']
            },
            series: [{
                name: 'Net Profit',
                data: [44, 55, 57, 56, 61, 58, 63, 60, 66]
            }, {
                name: 'Revenue',
                data: [76, 85, 101, 98, 87, 105, 91, 114, 94]
            }, {
                name: 'Free Cash Flow',
                data: [35, 41, 36, 26, 45, 48, 52, 53, 41]
            }],
            xaxis: {
                categories: ['Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dic'],
            },
            yaxis: {
                title: {
                    text: '$ (thousands)'
                }
            },
            fill: {
                opacity: 1

            },
            tooltip: {
                y: {
                    formatter: function (val) {
                        return "$ " + val + " thousands"
                    }
                }
            }
        }
    }
  },
});

Extra Options

As you can see in the example above, we are returning an object with an options field inside. This is not redundant, it's because we have added some extra options to our template:

containerId

The template provided is rendered to an html code like this:

<div id="{{containerId}}"></div>

and then the ApexChart is built passing a selector with that containerId. It's useful to pass a custom containerId in case you need to render more than one chart.

callbacks

There are to callbacks available:

• beforeRender: this function is called once the ApexChart object is built, but before calling chart.render(). It's called with two params chart (the ApexChart instance) and template context (the same you passed to the template).
• afterRender: this function is called once the chart.render() function has been called. It's called with the params of beforeRender.

These callbacks are useful to get the chart instance so you can manipulate the chart later (for updating options, appending data, etc...).

Full Example

Template.main.helpers({
  options() {
    let template = Template.instance();
    return {
      containerId: 'luixalsContainer',
      callbacks: {
        // beforeRender: function(chart, context) { console.log(chart) },
        afterRender: function(chart, context) {
          console.log(chart);
          template.chart = chart;
        },
      },
      options: {
            chart: {
                height: 350,
                type: 'bar',
            },
            plotOptions: {
                bar: {
                    horizontal: false,
                    endingShape: 'rounded',
                    columnWidth: '55%',
                },
            },
            dataLabels: {
                enabled: false
            },
            stroke: {
                show: true,
                width: 2,
                colors: ['transparent']
            },
            series: [{
