The doc for line chart Labels states:
Displays labels showing the categories used to create each line (by coloring or line by).
But, if I have both line-by and coloring enabled, they are both included in the label, making them almost impossible to read and understand - see pic. Spotfire is applying AND and not OR. Line-by should take precedence, or allow the designer to choose one or the other, or both. Don't display both - the text can be too long and it detracts from the overall quality of the visualization.
thanks,
JP
In pic: Name column is the line-by, and Leading column is the color-by
