I have tried it via WMS woth different style and it gives me quite correct
results. I have tried it on dmeo data from GeoServer.

I have tried the Barnes Surface Interpolation with WPS request builder and it
gives me correct results. So there should be problem with styling.

I have the same problem with Barnes surface, but I was successful with
Heatmap. So you can try Heatmap instead of Barnes surface. The function may
work different than interpolation, but may be useful for you purposes (I do
not know them).
