Apex chart squashed in mobile view

[LemonPie22]

Using Filament v3.2.15 with the Apex charts plugin v3.1.2, my stacked bar chart is coming out squashed almost flat on a mobile phone.

My code:

<?php

namespace App\Filament\Widgets;

use App\Models\Quote;
use Illuminate\Support\Carbon;
use Filament\Forms\Components\DatePicker;
use Leandrocfe\FilamentApexCharts\Widgets\ApexChartWidget;
use Flowframe\Trend\Trend;
use Flowframe\Trend\TrendValue;

class QuotesChart extends ApexChartWidget
{
    /**
     * Chart Id
     *
     * @var string
     */
    protected static ?string $chartId = 'quotesChart';

    /**
     * Widget Title
     *
     * @var string|null
     */
    protected static ?string $heading = 'Quotes';

    // Set to full width
    protected int | string | array $columnSpan = 'full';

    // Filter options
    protected function getFormSchema(): array
    {
        return [

            DatePicker::make('date_start')
                ->default(now()->subRealMonths(6)),
            DatePicker::make('date_end')
                ->default(now()),
        ];
    }

    /**
     * Chart options (series, labels, types, size, animations...)
     * https://apexcharts.com/docs/options
     *
     * @return array
     */
    protected function getOptions(): array
    {
        $dateStart = Carbon::parse($this->filterFormData['date_start']);
        $dateEnd = Carbon::parse($this->filterFormData['date_end']);

        $yAxis = Trend::model(Quote::class)
            ->between(
                start: $dateStart,
                end: $dateEnd,
            )
            ->perMonth()
            ->count();

        //@TODO Sort out code repetition below. No need for separate block for each status

        $declined = Trend::query(Quote::query()->where('status', 'declined'))
            ->between(
                start: $dateStart,

                end: $dateEnd,

            ->perMonth()
            ->count();

        $published = Trend::query(Quote::query()->where('status', 'published'))

            )
            ->perMonth()

            ->between(
                start: $dateStart,
                end: $dateEnd,
            )
            ->perMonth()
            ->count();
