Hi @niunaiyi , sorry for late response. So what I understand is, you use custom bar-chart https://coroo.github.io/nova-chartjs/#/?id=bar-chart. But unfortunately, the nova-chartjs still call data from db, am I right?

[niunaiyi]

looks like this:

class NovaServiceProvider extends NovaApplicationServiceProvider {

/**
 * Get the cards that should be displayed on the default Nova dashboard.
 *
 * @return array
 */
protected function cards()
{
	\Log::info('return cards');
	$data = getDataFromDB();
	$style = ...;
	$options = ...;
	return [
		(new LineChart())
		  ->title('title')
		  ->series($data, $style)
		  ->options($options)
		  ->width('full'),
	];
}

}

when i click any menu, NovaServiceProvider will return Cards serval times, then getDataFromDB will be called serval times.

Atfer I see the documentation at laravel nova. There is an issue about that: in here, which is still in development stage in laravel nova. The best answer for now is, you can use hotfix from ibrunotome:

protected function cards()
{
   if (request()->is('nova-api/dashboards*')) { // your dashboard url
	\Log::info('return cards');
	$data = getDataFromDB();
	$style = ...;
	$options = ...;
	return [
		(new LineChart())
		  ->title('title')
		  ->series($data, $style)
		  ->options($options)
		  ->width('full'),
	];
    }
}

hope this help you
