How to draw a dynamic line?

Question

I want to draw a line in OpenGL that will get new points very often. I want to achieve that the object draws a line behind it.

So I have to make an array and add all the new points to it (BufferData is set to GL_DYNAMIC_DRAW). And then redraw the line using glDrawArrays. Tessellation + stroke width will be inside the top?

Or is there a better way?

OpenGl

gl.glBufferData(gl.GL_ARRAY_BUFFER, 8 * self.maxPoints, None, gl.GL_DYNAMIC_DRAW)
# 8 bytes 2 points = 1 plot
# maxPoints amount of max plots

2 (gl.glBufferSubData). ? ? :
