That circuit will only monitor voltages of 1.25v or less. If you were to use that circuit as drawn, you should connect a 620 ohm resistor in series with T2, which is the LED brightness control. This will limit LED current to about 20ma each, which still may be too much current for the LM3914 if all LEDs are on and your LED supply voltage is more than about 8 or 9 volts.
What is the range of the voltage you are wanting to monitor? What is your supply voltage? How much current do you want to run through each LED? Answer these questions and we (I) can draw a complete schematic for you. I know that you said you wanted dot mode as opposed to bar mode. This will save power.
