SYMPTOM:
When a graph with multiple metrics, each having its own formatting, is configured as a Time Series Widget on a Flash dashboard with a metric selector, the formatting of the Y axis label does not change to match the selected metrics when the widget property "inherit graph formatting" is applied, in Strategy Web 9.3.0.
In the image below, Profit Margin was configured as percent.

STEPS TO REPRODUCE:
CAUSE:
This is a known issue with Strategy Web 9.3.0.
ACTION:
Contact Strategy Technical Support for an update on this issue.
WORKAROUND:
If the user does not require specific graph formatting to be applied, unchecking the "inherit graph formatting" option will allow the Y axis labels to match the selected metric formatting.
