### Bug report

Given a domain when the set of data provided to VictoryBar contains missing values the chart bars overlap.
In the Code Sandbox (link provided above), you'll be able to toggle between 3 scenarios and see the associated charts:

- Discontinuous data - bars overlap

- Missing data subbed with zero - bars don't overlap

- Full data - bars don't overlap

### Steps to reproduce

Head to the code sandbox link I provided and toggle between the different scenarios (discontinuous data - bars overlap, missing data subbed with zero - bars don't overlap, full data - bars don't overlap) and see how the bars behave.

### Expected behavior

In the context of a discontinuous set of data provided to VictoryBar the bars don't overlap in the graph.
We expect Victory to calculate and adjust the width of the bars given the dataset and the domain.

### Actual behavior

In the context of a discontinuous set of data provided to VictoryBar the bars overlap in the graph.
