A significant technical change has taken place under the hood at the weather station in Nauvo, even though the outward changes are small. The PHP scripts behind the site had to be updated in order to move to the new version of PHP, version 8.x, on the web host. The previous version, PHP 7.x, is no longer maintained.
The biggest technical change concerned the charts. Previously, they were rendered as ready-made images by server-side scripts, but since the JpGraph library used no longer worked with PHP 8.x, the site’s charts are now generated so that the underlying PHP script retrieves the data from the database and then provides it in JSON format to the JavaScripts that draw the charts.
The charts now look quite different. You can view them here: https://rosti.fi/saa/24-h-charts/?lang=en
