Bug - chart legend tooltip - missing space between label and value

[dlabrecq]

When we have only one item in the chart (or items of the same length), there is no space between the label and value.

See Cost Management issue https://issues.redhat.com/browse/COST-5648

The underlying issue is that "Cats" and "Dogs" may be the same number of characters, but they are not always the same length within a font family.

This is reproducible below when hiding all but one data set (i.e., only "Birds" is visible).

Example 1

As a second test, change the data series legendItem; "Cats" to "us-west-1" and "Dogs" to "us-west-2"
