This demonstrates how a bargraph display works. The LM3914 contains a bunch of comparators and a bunch of resistors creating a voltage divider.

Each comparator compares the input voltage (provided by a sine generator in this example)  to a fraction of a reference voltage you provide to this chip (1V DC source).

Lol i just commented on another similar design made by you. I see you applied the concept i was trying to explain over the previous design. My bad. Good design.
