Is there any way to identify the status of the search job attached to a visualization inside "updateview" method

I am creating a custom visualization as given in this link

Visualization is working fine.

Only problem I am facing is the the animation I gave as getting triggered more than once. The reason is the "updateview" method is getting triggered for all intermediate results.

I just want to show the result only when the job got competed.

Is there any way to identify the status of the search job inside "updateview" method of SplunkVisualizationBase

@paramagurukarthikeyan the behavior of Splunk Visualizations (in fact Splunk Search), is to keep returning results as they are processed. So ideally, visualizations should be created in a way that they show intermediate results as data keeps getting pulled in Splunk, rather than showing empty panel and waiting for search to complete (what if it takes 30 min.)?

One of the crude way to implement the behavior you are looking for is to use depends and rejects on a token that is unset in Search <progress> event handler and then set in <done> event handler.

Following is a run anywhere example of a long running search which shows a Spinner Wheel when the search is running and switches to Timechart when the search completes.

<dashboard>
  <label>Update View</label>
  <row>
    <panel> 
     <!-- HTML Panel for Spinner -->
     <html rejects="$displayViz$">
       <h2>Search is running!</h2>
       <!-- CSS Style to Create Spinner using animation -->
       <style>
         .loadSpinner {
           margin: 0 auto;
           border: 5px solid #FFF; /* White BG */
           border-top: 5px solid #3863A0; /* Blue */
           border-radius: 50%;
           width: 20px;
           height: 20px;
           animation: spin 1s linear infinite;
         }
         @keyframes spin {
           0% { transform: rotate(0deg); }
           100% { transform: rotate(360deg); }
         }
         <!-- CSS override to hide default Splunk Search Progress Bar -->
