This interface allows gnuplot to be controlled from C++ and is designed to be the lowest hanging fruit. In other words, if you know how gnuplot works it should only take 30 seconds to learn this library. Basically it is just an iostream pipe to gnuplot with some extra functions for pushing data arrays and getting mouse clicks. Data sources include STL containers (eg. vector), Blitz++, and armadillo. You can use nested data types like std::vector<std::vector<std::pair<double, double>>> (as well as even more exotic types). Support for custom data types is possible.

This is a low level interface, and usage involves manually sending commands to gnuplot using the "<<" operator (so you need to know gnuplot syntax). This is in my opinion the easiest way to do it if you are already comfortable with using gnuplot. If you would like a more high level interface check out the gnuplot-cpp library (http://code.google.com/p/gnuplot-cpp).

Example 1

Itv Dvber 2016 -

Many ITV shows from 2016 (reality shows like The X Factor or Sunday Night at the Palladium) used licensed pop music. On streaming, those songs are often replaced with generic library music. DVB recordings preserve the original broadcast audio.

2016 was a transitional year for UK television archiving. Several factors make recordings from this year uniquely valuable: itv dvber 2016

Speaking of daytime, October was a month of transition. It was the first full month of Piers Morgan’s reign as a permanent co-host on Good Morning Britain alongside Susanna Reid. Viewers were quickly learning that "breakfast TV" now meant confrontation and heated debates. Morgan’s abrasive style was drawing attention, but it was also carving out a distinct identity for the show, which had struggled to define itself since the departure of Daybreak. The ratings were slowly creeping up, proving that controversy does, indeed, sell. Many ITV shows from 2016 (reality shows like

While ITV's Freeview broadcasts are Free-to-Air (FTA), some satellite recordings from 2016 might still contain "broadcast flags" or specific regional variations (Granada, London, Meridian) that make files hard to play on standard media players without remuxing. 2016 was a transitional year for UK television archiving

While ITV had launched HD channels years prior, many viewers still recorded from SD channels due to hard drive space limitations. 2016 represented a peak time where SD Transport Streams were still widely available, easy to edit, and required less processing power than today's compressed streams.

While public torrent indexes are poor for this specific query, specialist TV archiving communities (like MySpleen or certain Reddit r/DataHoarder threads) sometimes preserve "scene" releases of raw ITV captures. Search for "ITV TS rip 2016" rather than "Dvber."
