This is complicated by having multiple series to begin with. For the
conditional coloring, you can use this approach:

To get this along with the clustered columns, you need to apply the
staggered data as described in the examples linked from this page:

Hello,

I would like to create a bar with 3 series (2bars, 1trend). On the bars, I
would like that above a certain value, the bar change of color (just the
part
above the value), is it possible?
Thank you.
