安装

通过Composer

将webit/downsampling添加到composer.json

{
    "require": {
        "php":              ">=7.1",
        "webit/downsampling": "^2.0.0"
    }
}

用法

use Webit\DownSampling\DownSampler\LargestTriangleThreeBucketsDownSampler;

$data = array();
for ($i=0; $i < 500; $i++) {
    $data[] = [$i, mt_rand(0, 200)];
}

$sampler = new LargestTriangleThreeBucketsDownSampler();
$sampled = $sampler->sampleDown($data, 100);
echo count($sampled); // displays 100
