NeoPixel Project for Display, Code Request

Good Morning,
Thank you reading my request.

I have a display which I am using 9 neopixel RGB LEDS from the underneath which lights up a couple of Transmitting Tubes and a Name-plate.
I have used the neopixel library, with individual LEDS and stung them together.
I have been able to get the code to work, however the string of LEDs, move from one LED to another. This is nice, but I would like it to be a solid colour across all the LEDs, fade out and them fade in to the next colour.

I also have a ir control from a commercial RGB string that I would also like to use to control the colour and the mode. I have purchased a ir receivers that I can use with the Pro-mini.

Any help would be grateful.

Regards Kevin.
