I'm searching the simplest and smallest library possible what just allows me
to draw time series graph (lines), rendering it to a windows anytime requested.
( so I can visualise data while the program's process is going on. )
Basically what I need is 2D graph, x being time step and y some paramater what changes over time and library would let me draw multiple lines with different color (RGBA format) and allows me to control alpha so I can find the best visualization confirmation when lines overlap.
It is really easy to use but kinda tricky to install on visual studio.
I downloaded Qt 5.4 from https://www.qt.io/download-open-source/
You'll get the installer what gives you alot of options what to download.
You only need msvc2013_64 ( or msvc2013_32 for 32bit op )
Then after you add include/lib folders and add libraries to a linker input, you need to
moc qcostomplot.h/qcostomplot.cpp
