[BUG] Regression introduced for stacking xAxes (at v2.5)

Expected Behavior

Bars should overlay one another — note that I don’t mean stacked on top of one another; the vertical start position of each bar should remain at the bottom (y=0). This is accomplished via xAxes: [{ stacked: true }]. Demo of desired functionality working w/v2.4.

Current Behavior

stacked does not appear to have an effect in the xAxes property.

Possible Solution

Steps to Reproduce (for bugs)

Demo of desired functionality not working w/v.2.5

Context

I’m trying to recreate vizwit.io using Chart.js and this is the most essential feature to show “filtering” of “totals.”

Environment

• Chart.js version: v2.4 and v2.5
• Browser name and version: Chrome latest
• Link to your project: http://vizwit.io
