How to hide unknown line?

[4n70w4]

Hi! I copy examples from readme and pass my parameters and data attributes:

    /**
     * Should return settings for Nova Chart in prescribed format
     *
     * @return array
     */
    public function getNovaChartjsSettings() : array {
        return [
            'default' => [
                'type' => 'line',
                'titleProp' => 'name',
                'identProp' => 'id',
                'height' => 400,
                'indexColor' => '#999999',
                'color' => '#FF0000',
                'parameters' => collect(self::data($this->getAttribute('id')))->pluck('k')->toArray(),
                'options' => ['responsive' => true, 'maintainAspectRatio' => false],
            ]
        ];
    }



    /**
     * Return a list of additional datasets added to chart
     *
     * @return array
     */
    public function getAdditionalDatasets(): array {
        return [
            'default' => [
                [
                    'label' => 'Distribution',
                    'borderColor' => '#f87900',
                    'fill' => '+1',
                    'backgroundColor' => 'rgba(20,20,20,0.2)',//For bar charts, this will be the fill color of the bar
                    'data' => collect(self::data($this->getAttribute('id')))->pluck('v')->toArray(),
                ],
            ]
        ];
    }

A line appears with the title of the Unknown. I don't understand how to remove it at all.

@4n70w4 Can you just confirm what the final dataset that's being sent to the panel is? From this screenshot, it looks like there might be an extra array key (possibly empty) in the dataset that's causing that Unknown element to be displayed.
