Define histogram bins with specified domain.

rather than with extent of data

Test notes

• Open the Webcharts config-tester.
  1. Choose histogram in the Chart Configuration dropdown.
  2. Add a custom domain to the X-axis Settings: domain: [0,7].
  3. Click the Render Chart button.
  4. Verify that the number of bars in the histogram remains the same.
  5. Choose histogram-domain in the Webcharts Version dropdown.
  6. Verify that the number of bars in the histogram decreases. This behavior is desired when the domain is explicitly defined in the chart configuration. Bar widths should be a function of the domain size rather than the range of the data.

Spencer is going to update the config tester so that we can test out this update. Test notes and config tester updates coming soon.

Updates that are necessary: point to new data file locations and add safety histogram to drop-down
