How to exclude data with "?"

Hey guys, is there a way to exclude/filter out data with “?”

Also, is there a node that looks like this in KNIME?

Red question marks represent so called “Missing Values”. You can use a Missing Value node for that. It has several options how to treat those missing values.


Hi @Leviheichou

@qqilihq already gave you good help to you by suggesting the missing values node!

Now for your question about the graph: you can use the bar chart node.
