I have used the Grafica library. I was able to plot signals separately in each plot. But I need multiple lines in one plot in real-time.

i not understand,  
what you show has 3 different curves already

* * *

if a library not does what you want,  
you better learn to do it better / without a library,  
that is why i link you to a example with 2 manual plots in one graph.  
with 5 line code function.

[https://jagracar.com/sketches/oktoberfest.php](https://jagracar.com/sketches/oktoberfest.php)  
would be a example from grafica lib for 2 series of data in one plot,  
by using 2 arrays.

if you decide to use one lib you might check out all examples what come with it.

if you can define line colors and symbols like that i not know.  
you tell us after you found out.
