Node color expression in Sankey Diagram (Qlik Visualization Bundle)

Hi,

Im trying to set node's color automatically instead of setting a fixed color for each dimension value.

I found a trick using this :

Color(round(255*rand( ),1))

But does anyone ever tried to set color by measure value ?

I tried this in Node Color exp :

if( MyMeasure>500,Red(),Green())

But the value displayed differs from the value measured in Node color :

AB = 511, so is > 500, but still green colored

but when I change my Node Color Exp to :

if( MyMeasure=75,Red(),Green())

AB is now Red..

My goal is to have a gradient Color by measure like we can have in all other elements.

Thanks

Ah, crap. This is all I've found when searching for the same issue, and so it seems like it's just a bug. If I do:

IF(Dimension = 1, color('#hexcodeA'), if(Dimension = 2, color('#hexcodeB'))

Then I just get all of it coming out as hexcodeA in colour.

If I swap the two palettes over, then it all comes out as hexcodeB. BUT, if I use, say, Red(), then it works and you see two colours.

It seems to just be a bug with using multiple hex colour values.

Actually typing this out gives me an idea, maybe I can try converting to RGB and using that? Maybe it's just the actual HEX values that are breaking. Will give it a go.

/EDIT: Yeah. Using rgb(x,y,z) instead of color('#hexcode') fixes it.
