Daviz is a data visualisation tool for IOS. The App works both on iPhone and iPad. The macro language which is used by Daviz is very similar to the one you can find in Plot2
In the App you have to enter a data source which is just an URL. In the simplest case this can be a text file which provides data and formatting information (See documentation at https://davizdoc.micw.org).
It is also possible to send data directly via IOS sharing to Daviz.
