Current behavior Vertical bars are not correctly aligned.

Expected behavior The vertical bars should be aligned.

Reproduction of the problem Simply create an angular 7.2.0 app, install ngx-charts 10.0.0, add a ngx-charts-bar-vertical component and look closely at the base of the bars, they are not aligned.

https://stackblitz.com/edit/angular-exixgx

Look closely at the chart, the 2nd bar (data = 0) extends below the 1st, the 3rd base is above 0, and the 4th one looks aligned with the 1st.

What is the motivation / use case for changing the behavior? The vertical bar charts used by our application look bad because the base is not correctly aligned.

Please tell us about your environment:

• ngx-charts version: 10.0.0

• Angular version: 7.2.0

• Browser: [Chrome 71.0.3578.98 ]

• Language: [all | TypeScript X.X | ES6/7 | ES5]
