Can you guide me how to display the value in the Line chart rather than need to mouse rollover on it?

Dashboard package :

<?php

namespace App\Dashboard\SI;

use koolreport\dashboard\widgets\google\LineChart; use \koolreport\dashboard\fields\Text; use \koolreport\dashboard\fields\Currency; use \koolreport\dashboard\ColorList;

use App\Dashboard\AutoMaker;

class ARLSI extends LineChart {

protected function onInit()
{
  $this->title("ARL")
    ->colorScheme(ColorList::random()); 
}

protected function dataSource()
{
            $range = $this->sibling("SIDateRange")->value();
	
	$datefrom = $range[0];
	$dateto = $range[1];
	 
	return AutoMaker::rawSQL("
                    Select SIDate ,  total
		from SI_HDR 
		where SIDate between '$datefrom' and '$dateto'
			");
}

protected function fields()
{
    return [
        Text::create("SIDate "),
        Currency::create("total")
                ->MYR()
                ->symbol()
                ->decimals(0)
    ];
}

} ?>

I have read this posted, but I don't know how to apply

"columns"=>array(

			"Monat",
			"{{all}}"=>array(
				"type"=>"number",
				"prefix"=>"",
				"suffix"=>"",
				"decimals"=>2,
				"thousandSeparator"=>".",
				"decimalPoint"=>",",
				"annotation"=>function($row)
				{
					//return "$".number_format($row["{{all}}"]);
					return $row["{{all}}"];
				},
			)
		),

in my code whereby

protected function onInit() { $this->title("ARL")

->colorScheme(ColorList::random()); 

}

protected function dataSource() {

        $range = $this->sibling("SIDateRange")->value();

$datefrom = $range[0];
$dateto = $range[1];
 
return AutoMaker::rawSQL("
                Select SIDate ,  total
	from SI_HDR 
	where SIDate between '$datefrom' and '$dateto'
		");

}

protected function fields() {

return [
    Text::create("SIDate "),
    Currency::create("total")
            ->MYR()
            ->symbol()
            ->decimals(0)
];

}

Can you guide me along?

I got it done. Thanks.
