CLI plotting commands inconsistent
When using the plotting commands for bob, some of the parameters are expected to be separated by space, and some by comma. For example, the following command does not work:
bob bio dir scores-1 scores-2 --legends label-1 label-2
This raises the error:
Usage: bob bio dir [OPTIONS] [SCORES]...
Try 'bob bio dir -?' for help.
Error: Invalid value: Number of legends must be >= to the number of systems
In fact, the score files must be separated by space, and the legends by comma, in order to work:
bob bio dir scores-1 scores-2 --legends label-1,label-2
Is there any particular reason for this behavior, i.e., is this expected?
