Dashboard 2.0 - Bar chart not showing negative values

Content

I am unsure if this is expected functionality or am I missing out something when creating a bar chart in Dashboards 2.0. I have a webform with 3 accounts on columns and scenarios on rows. On viewing the form the values show up on the form, but using the form in the bar chart shows the chart blank. this happens when the values are negative. If I remove the account which has a negative value, the bar chart works fine.

The same form when used with Dashboard 1.0 show bars with negative values fine.
