The Web Visualisation of Real Signals

This paper describes the processing and visualisation of measured real signals using a web interface. Real signals often contain large amounts of data. In order to derive the required information and values from these signals, an application must process them and generate clear and simple output formats - usually in the form of charts. These charts should have an interactive character, with many properties and parameter settings. In the web interface, many visualisation frameworks solve this problem. This article describes some of them - suitable for use in real environments. It is followed by the next part, in which new testing applications were designed and included in these frameworks. There is also a discussion of practical experience with them, using large real data from the industrial environment.
