Dynamically Updating a Highcharts Graph from Realtime.txt
This page describes how to implement a simple dynamically updating chart using Highcharts, PHP, realtime.txt, and AJAX.
Requirements
The web server must have..
- PHP
- Cumulus Realtime.txt
Installation
- Download and copy the Highcharts files on to your web server
- Download the GNU utilities for Win32 - I used the latest updates (after 14-04-03)
- Download the Realtime_Highcharts ZIP file (right click, Save as)
Next you have to decide where and how the realtime log file will be created. The zip file contains a simple Windows batch file that will create a log file of a specified length. If you have a Windows web server you could run it directly on there (this is how I do it), or run it on your Cumulus computer and get Cumulus to upload the log file periodically.
Alternatively Kevin at TNET Weather has created a PHP script to create such a log file. The batch file is simple and creates a limited length log file, the TNET scripts typically create much larger log files, and the realtimeLogParser.php script I have written returns all the entries it finds in the file. It would require amendment to work with the larger TNET logs.
