How to hide loading spinner

Hi Bilguun,
 
Thank you for writing to us.
 
The row count in the data loading pop-up can be hidden with your custom pivot table localization:
 

global: {
    localization: {
        "messages": {
            "progress": "",
            "progressKnown": "",
            "progressUnknown": "",
            "analyzingProgress": "",
            "analyzingRecords": "",
        }
    }
},

 
This will override the default labels displayed in the pop-up in a way that empty strings will be displayed instead of the loading info. Naturally, the same way you can modify many other labels in the pivot table. Please see the following sample for illustration: https://jsfiddle.net/flexmonster/z2jfgb5c/

We hope this helps.
