Text color depending on chartbar color

[#1]

Hi, I'm trying to use 2 diffrent text colors depending on the color of the bar at a chartbar. I'm editing the axes font, using calculated color, but I don't know how to call de color of the bar.

[ code ]

If( ¿? = rgb(x,y,z), rgb(a,b,c), rgb(x,y,z)

[ /code ]

Any ideas?

Thanks!!!
