Inquiry about Color Manager node

KNIME Analytics Platform
1

Hello.

I was wondering how can I apply a color to a new value when using the custom option.

I don’t think I can run it when there is a new value.

I would appreciate it if someone could help me :slight_smile:

Thanks,
Hhkim

Hi @hhkim,

When using the custom color option in the Color Manager, you need to map all possible values in your data. If a new, unseen value appears at runtime, the node will fail.

In that case, it’s often better to use the set color option, which assigns colors from a palette to unknown values properly.

Best,
Keerthan
