What Version?

3.1.14

Issue

I am getting this error ( "Cannot read property 'style' of null" ) in a red box, when checking the html code, I found: "google-visualization-errors-all-1"

Controller Code (chart creation code)

$lava = new Lavacharts();
        $entries =  $lava->DataTable();
        $query = Survey::select('country AS 0', \DB::raw('count(country) AS entries'))->groupBy('country')->get()->toArray();

        $data = [];

        foreach ($query as $q) {
            $data[] = [$q[0], $q['entries']];
        }


        $entries->addStringColumn('Country')
                   ->addNumberColumn('Popularity')
                   ->addRow(array('Germany', 200))
                   ->addRow(array('France', 200))
                   ->addRow(array('Italy', 200));

        $lava->GeoChart('Popularity', $entries);

        return view('dashboard.homepage', ['colorsNum' => $colorsNum, 'lava' => $lava]);

View Code

 <div class="row">
                <div class="col-md-12">
                  <div class="card">
                    <div class="card-body">
                    <div id="pop-div"></div>
                      // With the lava object
                      <?= $lava->render('GeoChart', 'Popularity', 'pop-div') ?>
                  </div>
                </div>
              </div>

It loos like you are using Laravel so you should be using the service provider examples \Lava::GeoChart() for example.

The class is a singleton within the service provider, so you don't have to do $lava = new Lavacharts(); that

and then calls like $lava-> should be \Lava:: and you don't have to pass anything to the view.

There are blade aliases available and you would again, in the view, reference the service provider.

It does not work, I remember that I tried the static ones too. I was using Laravel 8, I gave up and used directly google's API for maps.

fair enough, I don't have time anymore to work on this, I apologize. It was my passion project before my real-life, living passion project was born (my daughter) 😅
