Showing a horizontal and vertical line in the chart area but between two points not entirely

**Is your feature request related to a problem? Please describe.**
I need to show two horizontal lines line with a label like in the image:

**Describe the solution you'd like**
I think, if the existing HorizontalLine and VerticalLine take ranges like fromX , toX, fromY, toY then it will be very useful.

Also, it will be good if it is possible to place a widget in a given x,y point.

Start by locating the existing HorizontalLine and VerticalLine implementations and reviewing how chart coordinates are mapped to the drawing area. Determine how bounded ranges and labels would fit those APIs, then investigate the chart entry point for placing a widget at an x,y coordinate. Done means both line types support bounded segments and the requested point widget behavior is covered by tests or documented examples.
