Fix Admin Overview Graphs

The NATS3 Chart Director allows you to display various graph images of your NATS program's statistics in areas like the Admin Overview page, for example. However, there may be times (usually after a server move) when your graphs may not load properly for your admin pages.

Re-Installing Chart Director

If your graph images are not being displayed on the Admin Overview page, follow the provided instructions:

  • Find out what system you are using (Linux, FreeBSD, etc.)
  • Navigate to the nats/includes directory.
  • Go to the official Chart Director page, located at
  • Copy the download link for the version you need into your SSH client, and perform a wget or fetch to download Chart Director to your includes directory.
  • Once you have downloaded Chart Director, unzip the provided files into the includes directory with the "tar -xzf <filename>" command.
    • Replace <filename> in the above example with the Chart Director's file name.
    • These files must be loadable by the "extension_dir" function.
  • Make sure that your extension_dir directory contains the following files:
    • phpchartdir.php
    • FinanceChart.php
    • Any .dll file beginning with "phpchartdir". For example: phpchartdir404.dll
