Strongly inspired by Leandro Ferreira’s Apex Charts plugin, this plugin delivers Apache ECharts integration for Filament.

#Installation

You can install the package via composer:

composer require elemind/filament-echarts

Register the plugin for the Filament Panels you want to use:

use Elemind\FilamentECharts\FilamentEChartsPlugin;
public function panel(Panel $panel): Panel
{
    return $panel
        ->plugins([
            FilamentEChartsPlugin::make()
        ]);
}

#Usage

Start by creating a widget with the command:

php artisan make:filament-echarts BlogPostsChart

#Available chart samples

You may choose:

• Line
• Bar
• Pie
• Scatter
• Candlestick
• Radar
• Boxplot
• Sunburst
• Parallel
• Sankey
• Funnel
• Gauge

#Setting a widget title

You may set a widget title:

protected static ?string $heading = 'Blog Posts Chart';

Optionally, you can use the getHeading() method.

#Setting a widget subheading

You may set a widget subheading:

protected static ?string $subheading = 'This is a subheading';

Optionally, you can use the getSubheading() method.

#Setting a chart id

You may set a chart id:

protected static string $chartId = 'blogPostsChart';

#Making a widget collapsible

You may set a widget to be collapsible:

protected static bool $isCollapsible = true;

You can also use the isCollapsible() method:

protected function isCollapsible(): bool
{
    return true;
}

#Setting a widget height

By default, the widget height is set to 300px. You may set a custom height:

protected static ?int $contentHeight = 400; //px

Optionally, you can use the getContentHeight() method.

protected function getContentHeight(): ?int
{
    return 400;
}

#Setting a widget footer

You may set a widget footer:

protected static ?string $footer = 'Lorem Ipsum is simply dummy text of the printing and typesetting industry.';

You can also use the getFooter() method:

Custom view:

use Illuminate\Contracts\Support\Htmlable;
use Illuminate\Contracts\View\View;
 
protected function getFooter(): null|string|Htmlable|View
{
    return view('custom-footer', ['text' => 'Lorem Ipsum is simply dummy text of the printing and typesetting industry.']);
}

<!--resources/views/custom-footer.blade.php-->
<div>
    <p class="text-danger-500">{{ $text }}</p>
</div>

Html string:

use Illuminate\Contracts\Support\Htmlable;
use Illuminate\Contracts\View\View;
protected function getFooter(): null|string|Htmlable|View
{
    return new HtmlString('<p class="text-danger-500">Lorem Ipsum is simply dummy text of the printing and typesetting industry.</p>');
}

#Hiding header content

You can hide header content by NOT providing these

• $heading
• getHeading()
• $subheading
• getSubheading()
• getOptions()

#Filtering chart data

You can set up chart filters to change the data shown on chart. Commonly, this is used to change the time period that chart data is rendered for.

#Filter schema

You may use components from the Schemas to create custom filters. You need to use HasFiltersSchema trait and implement the filtersSchema() method to define the filter form schema:

use Filament\Forms\Components\DatePicker;
use Filament\Forms\Components\TextInput;
use Filament\Schemas\Schema;
use Filament\Widgets\ChartWidget\Concerns\HasFiltersSchema;
use Elemind\FilamentECharts\Widgets\EChartWidget;
 
class BlogPostsChart extends EChartWidget
{
    use HasFiltersSchema;
 
    public function filtersSchema(Schema $schema): Schema
    {
        return $schema->components([
            TextInput::make('title')
                ->default('Blog Posts Chart'),
 
            DatePicker::make('date_start')
                ->default('2025-07-01'),
 
            DatePicker::make('date_end')
                ->default('2025-07-31'),
        ]);
    }
 
    /**
    * Use this method to update the chart options when the filter form is submitted.
    */
    public function updatedInteractsWithSchemas(string $statePath): void
    {
        $this->updateOptions();
    }
}

The data from the custom filter is available in the $this->filters array. You can use the active filter values within your getOptions() method:

protected function getOptions(): array
{
    $title = $this->filters['title'];
    $dateStart = $this->filters['date_start'];
    $dateEnd = $this->filters['date_end'];
 
    return [
        //chart options
    ];
}

#Single select

To set a default filter value, set the $filter property:

public ?string $filter = 'today';

Then, define the getFilters() method to return an array of values and labels for your filter:

protected function getFilters(): ?array
{
    return [
        'today' => 'Today',
        'week' => 'Last week',
        'month' => 'Last month',
        'year' => 'This year',
    ];
}

You can use the active filter value within your getOptions() method:

protected function getOptions(): array
{
    $activeFilter = $this->filter;
 
    return [
        //chart options
    ];
}

#Live updating (polling)

By default, chart widgets refresh their data every 5 seconds.

To customize this, you may override the $pollingInterval property on the class to a new interval:

protected static ?string $pollingInterval = '10s';

Alternatively, you may disable polling altogether:

protected static ?string $pollingInterval = null;

#Defer loading

This can be helpful when you have slow queries and you don't want to hold up the entire page load:

protected static bool $deferLoading = true;
 
protected function getOptions(): array
{
    //showing a loading indicator immediately after the page load
    if (!$this->readyToLoad) {
        return [];
    }
 
    //slow query
    sleep(2);
 
    return [
        //chart options
    ];
}

#Loading indicator

You can change the loading indicator:

protected static ?string $loadingIndicator = 'Loading...';

You can also use the getLoadingIndicator() method:

use Illuminate\Contracts\View\View;
protected function getLoadingIndicator(): null|string|View
{
    return view('custom-loading-indicator');
}

<!--resources/views/custom-loading-indicator.blade.php-->
<div>
    <p class="text-danger-500">Loading...</p>
</div>

#Dark mode

The dark mode is supported and enabled by default.

#Extra options and Formatters

You can use the extraJsOptions method to add additional options to the chart:

use Filament\Support\RawJs;
 
protected function extraJsOptions(): ?RawJs
{
    return RawJs::make(<<<'JS'
        {
            yAxis: {
                axisLabel: {
                    formatter: function(value, index, extra) {
                        return value + ' votes';
                    }
                }
            }
        }
    JS);
}
