transparency on legend thresholds

[frank_forster]

Hi,
Is there a way to make one threshold of my dataset fully transparent. (> -2)
In addition, the holes you can see in the model are NoData with the same color as background.
Because I’d like to add some basemap below, is there a way to make it transparent too ?

If there’s no way to add transparency, is there a way to only extract one threshold and then export it in a new dataset ?

Thanks, Frank

Answering my own question,

I managed to exclude both Nodata and < -2 Data using Threshold :

You can also use opacity mapping. There’s a checkbox “Enable opacity mapping …” in the color map editor for that purpose.

Thanks for the complement @bastian
