OpenCV multigraph

This is a simple but useful utility implementation for a multi-graph time series visualization in python OpenCV. Features:

• multi signals on the same graph
• position, color, title settings
• markers setting for the interest points

How to use it?

1. clone the project
2. import in your project the utils/muligraph.py
3. create an instance for "multigraph" object rtmg = RealTimeMultiGraph(shape=[IMG_H,IMG_W,IMG_CHANNEL],nr_of_graphs=NR_OF_GRAPHS)
4. optionally set the graph color/parameters

ex. setup a single graph with parameters
# set properties
rtmg.set_color(0,[0,0,255])
rtmg.set_scale(0,10)
rtmg.set_offset(0,110)
rtmg.set_marker(0,value=5,size=2,color=[0,0,255])
rtmg.set_title_and_position(0,"sin/10",(10,10))

See details of a working example in python test_multigraph.py.

/Enjoy.
