Incubator-superset: Min bar width for NVD3 charts not maintained on chart with few columns.

[john-wormington-sp]

Bar Chart column width can become unusable when resizing browser. Long x-axis names exacerbates the issue. The issue appears to be tied to the number of columns in the bar chart and the allotted chart width. To try and limit the ui issues the screen shots below make use of a change to truncate the long x-axis names: https://github.com/apache-superset/superset-ui-plugins/pull/21

This issue seems similar: https://github.com/apache/incubator-superset/pull/629

Expected results

Minimum bar width maintained

Actual results

Bar Chart columns squished

Screenshots

Bar Chart with few columns, squished down vs Bar Chart with more columns that overflow outside the container.

How to reproduce the bug

1. Create a Dashboard with two bar charts, one with few columns, one with many columns.
2. Choose a chart width that is small, ex: chart position json meta width = 3
3. Resize (decreasing) browser window to see the chart render smaller and smaller column width until they are unusable on the chart with few columns. While the chart with many columns overflows

Environment

• superset version: [v0.999.0dev, master]

Is there a way to get around this issue?
Also is it possible to set a max width when number of bars are fever or only one or two - either with horizontal or vertical bar charts
