No Jeff,
Sorry, but I disagree with you.
You used a completely different circuit before, with Ref-ADJ grounded to provide a reference voltage of 1.25V, and Ref-OUT with a 1K resistor to ground to provide an LED current of about 12.5mA.
Also, if you used 1.8V red LEDs and the 12V supply, in the bar mode with all 10 LEDs lighted, the package is dissipating more than 1.28W! Very hot.
The datasheet says, "V-LED must be kept below 7V or dropping resistor should be used to limit IC power dissipation".
Here is your "hot" circuit from before with the IC's pins identified:
