ramp shader in combination with transparency

hi,

i'am looking for a ramp shader combinated with transparency like this one.

my knowledge about shader are very very low :-(

so someone can write a short instruction how to do it?

 

As far as I can see from your example you can do this with a standard alpha shader in Unity. Just make a texture with an alpha channel like the ramp from the example and assign that to your material.
