Plotting real time data in opencv using python

This repo can be used to plot single as well as multiple values in OpenCV python.

opencv-plot.py

Plot single integer values in realtime using this file.

Usage:

Create a plotter class object

p = Plotter(400, 200) #(plot_width, plot_height)   

Create dummy values using for loop

for v in range(500):    
	# call 'plot' method for realtime plot    
	p.plot(v/5)     

`

opencv-multiplot.py (Maximum: 9 values at a time)

Plot multiple values in reallime using this file.

Usage:

Create a plotter class object

p = Plotter(400, 200, 3) #(plot_width, plot_height)    

Create dummy values using for loop

for v in range(500):    
	# call 'plot' method for realtime plot    
	v1 = random.randint(0,200) - 100       
	v2 = int(math.sin(v*3.14/180)*100)      
	v3 = int(math.cos(v*3.14/180)*100)        
	p.multiplot([v1, v2, v3]) #List of all values to be plotted        

`

cvPLOT.py (use different label for each plot)

Plot multiple values in reallime in multiwindows with a simple

Usage:

Create a plotter class object

p = Plotter(400, 200, 100) #(plot_width, plot_height, sample_count)    

Create dummy values using for loop

p = Plotter(400, 200,sample_buffer=200)
    
    for v in range(1,3000):
        
        p.plot(int(math.sin(v*3.14/180)*100),label='sin') ## Add label 'sin' to show in a seperate window
        
        p.plot(int(math.cos(v*3.14/180)*50),label='cos')
