<?php
  public function create(array $checkins, bool $toDisk = false) {
    if($toDisk) {
      // wipe out the current image, if it exists
      $this->destroy();
    }

    // Create the graph
    $graph = new JpGraph\Graph(800, 600, 'auto');
    $graph->title->Set("Last 30 Days of Selected Behaviors");
    $graph->title->SetFont(FF_ARIAL, FS_BOLD, 20);
    $graph->SetImgFormat('png');
    $graph->img->SetImgFormat('png');
    $graph->SetScale("textlin");
    $graph->img->SetMargin(60, 60, 40, 140);
    $graph->img->SetAntiAliasing();

    $graph->SetShadow();
    $graph->ygrid->SetFill(false);

    // Setup dates as labels on the X-axis

    // format the data into something nicer
    $accum = [];
    foreach($checkins as $checkin_sum) {
      for($i = 1; $i <= 7; $i ++) {
        $accum[$i][] = array_key_exists($i, $checkin_sum) ? $checkin_sum[$i]['count'] : 0;
      }
    }

    // Create the bar plots
    $plots = [];
    $category = Yii::$container->get(\common\interfaces\CategoryInterface::class);
    foreach($accum as $category_key => $category_data) {
      $bplot = new BarPlot($category_data);
      $color = $category::$colors[$category_key]['color'];

      $bplot->SetColor($color);

    $graph->legend->SetColumns(3);
    $graph->legend->SetPos(0.5,0.98,'center','bottom'); // position it at the center, just above the bottom edge

    $img = $graph->Stroke(_IMG_HANDLER);

    ob_start();
    imagepng($img);

It seems like $img can also be of type false; however, parameter $image of imagepng() does only seem to accept GdImage|resource, maybe add an additional type check?

    $img_data = ob_get_clean();

    if($toDisk) {
      $filepath = $this->getFilepath(); 
      if(!is_dir(dirname($filepath))) {
        mkdir(dirname($filepath), 0766, true);
      }

      file_put_contents($filepath, $img_data, LOCK_EX);
    }

    return $img_data;
  }
