Hello,
I am using geoserver 2.12.1.
I successfully created a YSLD style that makes use of the interpolate
function:
feature-styles:
> - name: Yearly Cost
> rules:
> - title: fill-graphic
> symbolizers:
> - polygon:
> stroke-width: 0.1
> stroke-color: '#353535'
> fill-color: ${interpolate(yearlycost, 40366, '#e0ecf4', 46500,
> '#9ebcda', 61299, '#8856a7', 'color')}
However, when I click "Preview legend", I get an error message at the top
of the screen: "Failed to build legend preview. Check to see if the style
is valid."
This seems to be the pertinent portion of the logs:
