Installation
You can install the package via composer:
Next, you must export the package public scripts. To do this run php artisan vendor:publish
and export livewire-charts:public
. This command will export a vendor/livewire-charts
folder under the
public
directory of your app.
Requirements
This package requires the following packages/libraries to work:
Laravel Livewire v2
(https://laravel-livewire.com/)Alpine Js
(https://github.com/alpinejs/alpine)Apex Charts
(https://apexcharts.com/)
Please follow each package/library instructions on how to set them properly in your project.
Note: At the moment,
Apex Charts
is only supported for drawing charts.
Usage
Livewire Charts supports out of the box the following types of charts
- Line/Multi Line Chart (
LivewireLineChart
component) - Pie Chart (
LivewirePieChart
component) - Column/Multi Line Chart (
LivewireColumnChart
component) - Area Chart (
LivewireAreaChart
component)
Each one comes with its own "model" class that allows you to define the chart's data and render behavior.
LivewireLineChart
usesLineChartModel
to set up data points, markers, events and other ui customizations.LivewirePieChart
usesPieChartModel
to set up data slices, events and other ui customizations.LivewireColumnChart
usesColumnChartModel
to set up data columns, events and other ui customizations.LivewireAreaChart
usesAreaChartModel
to set up data points, events and other ui customizations.
For example, to render a column chart, we can create an instance of ColumnChartModel
and add some data to it
Note: Chart model methods are chainable 💪
With $columnChartModel
at hand, we pass it to our LivewireColumnChart
component in our Blade template.
Next, include the @livewireChartsScripts
directive next to your other app scripts
And that's it! You have a beautiful rendered chart in seconds. 👌
Note: You can use these charts inside other Livewire components too. Just render them in your Blade template and you are good to go. 👍
LivewireCharts facade
Chart models can also be created using the LivewireCharts
facade.
Enabling Interactions
To enable click events, you must use the with[XXX]ClickEvent($eventName)
method present in every model class and
define a custom $eventName
that will be fired with the corresponding data when a column/marker/slice is clicked.
Here we define an onColumnClick
event that will be fired when a column is clicked in our chart.
We can listen to the onClickEvent
registering a listener in any other Livewire component.
"Reactive" Charts
You can use livewire-charts components as nested components in you Livewire components. Once rendered, charts will
not automatically react to changes in the $model
passed in. This is just how Livewire works.
However, to enable "reactivity" when data passed in changes, you can define a special $key
to your components so they are fully re-rendered each time the chart data changes.
Each model class comes with a reactiveKey()
method that returns a string based on its data. If any of the properties
are changed, this key will update accordingly and re-render the chart again.
In the following example, a parent component houses both column chart and pie chart and defines a $model
for each one.
The parent component renders the charts as follows
When the parent component changes their respective models, charts will automatically re-render itself.
Charts API
For each chart, a specific model class needs to be used. Here, it is detailed the api available for each type of chart.

Advanced Usage - Integrating Scripts
The directive @livewireChartsScripts
adds a script
tag that includes public/vendor/livewire-charts/app.js
.
If you want to include this script in your build system, you can export the package scripts
with php artisan vendor:publish
and selecting livewire-charts:scripts
. This will export js/vendor/livewire-charts
inside your resources folder. You can then adjust imports as you see fit in your project.
Note: You must remove @livewireChartsScripts directive so it doesn't clash with the scripts in your build system.
Troubleshooting
Chart components must be placed inside a container with fixed height. This is because the chart will use all the given vertical space. A fixed height is needed to render properly.
Note: if a fixed height is not given, the chart will grow vertically infinitely. That's not what we want, right?
