# Chart Refresh irregular

 * The chart shows tidal height read from a sensor and written to the tidal.csv 
   file on the server every ten minutes. The update is irregular and does not happen
   when the page is refreshed. I’ve tried clearing the browser cache as well as 
   testing on a fresh browser.
 * How do I make the chart refresh regularly please?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fchart-refresh-irregular%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi there.
 * Did you try activating the [auto-update cache](https://wpdatatables.com/documentation/table-features/caching-data-and-auto-update-cache-in-wordpress-tables)
   in wpDataTables General Settings and in the “Data Source” tab in Table settings?
 * This is useful for linked tables that are frequently edited, as it appears to
   be in your case. You’d need to configure a cron job that runs frequently (every
   minute, for exapmple), in order to pull the data from the file on the server 
   and automatically update the table when it runs (if there was a change between
   the two runs).
 * Let us know if that helps!

 * Sorry, could you give me an idea of what that cron job would look like?

 * Hello,
 * Apologies for the waiting time.
 * Certainly! We have a detailed, step-by-step guide in our documentation that explains
   how to set up a cron job for the **Auto Update Cache** feature:
   [https://wpdatatables.com/documentation/table-features/caching-data-and-auto-update-cache-in-wordpress-tables/](https://wpdatatables.com/documentation/table-features/caching-data-and-auto-update-cache-in-wordpress-tables/)
 * You can create the cron job directly on your hosting server, or — if you prefer
   an easier option — you can install the **WP Crontrol** plugin.
   Our guide includes
   a full tutorial showing how to use WP Crontrol, including the **exact cron command**
   you can copy and paste, as well as troubleshooting tips in case you encounter
   any issues.
 * If you run into any problems while setting this up, please don’t hesitate to 
   reach out to our main Support Team — just open a chat on our [site](https://wpdatatables.com/).
   
   We presume you’re using our free version, so simply select the **“Pre-Purchase”**
   category, and it will route you to our main support team.
 * Kind regards,
   Milos
