plot categorical data

[CarlSchwedes]

Hi there, I was wondered if plot juggler can also plot categorical data into its x/y line plots?

Imagine some strings to be encoded from real numbers OBJ/0/attribute0 -> 0 OBJ/0/attribute1 -> 1 OBJ/0/attribute2 -> 2 ...

Is there a way to directly print the attribute strings into a coordinate system (labels y-axis) instead of the number encodings?
