Choose Custom Legend?

If, for each line, you know the hostname, and instance name and dont need them displayed using tokens - that implies that there is only of each host/instance combo, in which case you don;t need (or arent using) wildcards or regular expressions - in which case you can disable the flexible checkbox, and there is no constraint.n

nWhen using flexible custom graphs, the assumption is that you are using the wildcard/regex facility, so there is no way to know what the lines are for without using tokens.
