This came up from the accessibility review obtained from @glarose.

There is no alt-text for the graph images that are dynamically generated on the Statistics page.

Possible remedies:

  1. Create alt-text for each graph. This would be theoretically possible, but could be quite tedious to create.
  2. Include the raw data used to generate the graph, either as alt-text for the image itself, or as additional content on the page (perhaps hidden by default).

Not sure how pressing this is since this is an instructor-only page and is not required for any core functionality.

Add alt text to histograms on stats page.

This adds alt text to the histogram images on the stats page which
fixes the issue mentioned in openwebwork#2598.

In addition this fixes some issues I found with the stats page.
* Links on the problem bars weren't working so forced them to
  be a string.
* JitarSets - The adjusted status bars were reversed and didn't
  need to be and the adjusted scores were multiplet by 100 and
  didn't need to be.
