You can install the package via composer:
composer require asantibanez/livewire-charts
Next, you must export the package public scripts. To do this run
php artisan livewire-charts:install
This command will export a vendor/livewire-charts
folder under the public
directory of your app which is used
by the @livewireChartsScripts
directive. More on this topic later.
This package requires the following packages/libraries to work:
Laravel Livewire v3
(https://livewire.laravel.com/)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.
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) - Radar Chart (
LivewireRadarChart
component) - Tree Map Chart (
LivewireTreeMapChart
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.LivewireRadarChart
usesRadarChartModel
to set up data points, events and other ui customizations.LivewireTreeMapChart
usesTreeMapChartModel
to set up data blocks, 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
$columnChartModel =
(new ColumnChartModel())
->setTitle('Expenses by Type')
->addColumn('Food', 100, '#f6ad55')
->addColumn('Shopping', 200, '#fc8181')
->addColumn('Travel', 300, '#90cdf4')
;
Note: Chart model methods are chainable 💪
With $columnChartModel
at hand, we pass it to our LivewireColumnChart
component in our Blade template.
<livewire:livewire-column-chart
{{-- key="{{ $columnChartModel->reactiveKey() }}" --}}
:column-chart-model="$columnChartModel"
/>
Note: Optionally add "key" to enable props reactivity if needed 💪
Next, include the @livewireChartsScripts
directive next to your other app scripts
<livewire:scripts />
@livewireChartsScripts
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. 👍
Chart models can also be created using the LivewireCharts
facade.
LivewireCharts::lineChartModel();
LivewireCharts::multiLineChartModel();
LivewireCharts::columnChartModel();
LivewireCharts::multiColumnChartModel();
LivewireCharts::pieChartModel();
LivewireCharts::areaChartModel();
LivewireCharts::radarChartModel();
LivewireCharts::treeMapChartModel();
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.
$columnChartModel =
(new ColumnChartModel())
->setTitle('Expenses by Type')
->withOnColumnClickEventName('onColumnClick')
;
Here we define an onColumnClick
event that will be fired when a column is clicked in our chart.
We can listen to the onClickEvent
registering a listener in any other Livewire component.
#[On('onColumnClick')]
public function handleOnColumnClick($event)
{
// Handle event
}
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
<livewire:livewire-column-chart
key="{{ $columnChartModel->reactiveKey() }}"
:column-chart-model="$columnChartModel"
/>
<livewire:livewire-pie-chart
key="{{ $pieChartModel->reactiveKey() }}"
:pie-chart-model="$pieChartModel"
/>
When the parent component changes their respective models, charts will automatically re-render itself.
For each chart, a specific model class needs to be used. Here, it is detailed the api available for each type of chart.

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.
The setJsonConfig()
method on every chart allows adding custom Apex properties not provided first hand by the package.
This means that any chart property supported by Apex chart can be passed down using this method.
$chart->setJsonConfig([
'plotOptions.pie.startAngle' => -90,
'plotOptions.pie.endAngle' => 90,
'plotOptions.pie.offsetY' => 10,
'grid.padding.bottom' => -180,
]);
Note: If you want to add nested properties, you can use dot (.) notation for this matter.
You can even pass down simple JS functions. For example, for formatting you can pass down your own closure
$chart->setJsonConfig([
'tooltip.y.formatter' => '(val) => `$${val} million dollars baby!`'
])
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.
<div style="height: 32rem;">
<livewire:livewire-column-chart .../>
</div>
Note: if a fixed height is not given, the chart will grow vertically infinitely. That's not what we want, right?
