Issue

I am having issue of lava object undefined in blade file for ajax call, however this same code in controller works fine for non-ajax code.

Controller Code (chart creation code)

$temps = Lava::DataTable();

foreach ($sensor_status as $sdata) {
 
$temps->addStringColumn('Type')
      ->addNumberColumn('Temp')
      ->addRow(['Temp', $sdata->temprature])
      ->addRow(['Humidity', $sdata->humidity]);
Lava::GaugeChart('Temps', $temps, [
    'width'      => 400,
    'greenFrom'  => 0,
    'greenTo'    => 69,
    'yellowFrom' => 70,
    'yellowTo'   => 89,
    'redFrom'    => 90,
    'redTo'      => 100,
    'majorTicks' => [
        'Safe',
        'Critical'
    ]
]);
}//
return $temps->toJson();

View Code

 -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

$.ajax({
  
    url:val,
    type: "POST",
    data:{data_id:d_id},
    success:function(result)
    {
 lava.loadData('Chart1', result, function (chart) {
    console.log(chart);
  });

I suppose my docs aren't clear enough, but the chart has to be rendered once with a empty datatable with the correct structure. This way the ajax know how to fill the chart.

<div id="chart-div"></div>
// With Lava class alias
<?= Lava::render('ScatterChart', 'AgeWeight', 'chart-div') ?>

// With Blade Templates
@scatterchart('AgeWeight', 'chart-div')

for example, that would render the chart into the page (but also includes the script tag for lava.js!!)

This code for non-ajax call that is working fine. I have to display on ajax call using above code example you have given in doc

[kevinkhill]

try wrapping the ajax call in lava.ready() because I think your on page load call beats the google chain of getting everything loaded

[muazzamazaz]

I have tried that already but its not loading anything about lava at blade template file.

Is your render call above/before the ajax? The php render method outputs the script tag with lava.js

No, I didn' t call lava.js since its already in package installed. How to call this? which path? I have copied it to public/js and call it but no success.

I checked back through my issue history and I think this might be what we're looking for... #215
