Org Chart caching

Org Chart for SharePoint Online and SharePoint 2013 uses client-side caching to improve performance.

Once you open the web part for the first time and navigate over boxes, they are cached in your browser for 24 hours. That is why you may not see modifications you did to your data source. In this case just clear cache using the menu item at the top right corner of the web part:

It is actual for vacancies and dotted line managers as well as for employee properties.

You can change default caching period using JavaScript framework. Pay attention to clientSideCachingLifeDays property. You can put custom JavaScript code into the code editor of the configuration wizard.
