Answer 1

You can find individually the minimum and maximum values of each column by combining array_column, min and max functions:

$min_x = min(array_column($dataPoints, 'x'));
$max_x = max(array_column($dataPoints, 'x'));
$min_y = min(array_column($dataPoints, 'y'));
$max_y = max(array_column($dataPoints, 'y'));
