Signal head

[dev3225]

User story

Could you explain why the feature is needed and how it should behave when multiple signals are to be displayed?

In an analog oscilloscopes, the CRT projects the beam onto the screen and that is how we are able to view the signal. Here we are trying to replicate what it would look like in an analog oscilloscope.
So, what we could understand from the client is that the point at which the signal is updated should have a kind of marker(here kind of a comet head) which makes it possible for the user to distinguish between already plotted signal and the point at which new data is being plotted.
