What happened?

Actual result: The StackedBarChart doesn't display data when the first key it receives is a string of negative number, e.g. key: "-6".

The chart works okay when:

• the first key is NOT a string of negative number, e.g. key: "-6";
• the first key is a string of negative number + text, e.g. key: "-6M";
• the first key is "-Some Key".

Expectations: The chart to display data when the first key that it receives is a string of negative number, e.g. key: "-6".
