Contrast Texture Adjustments#

Test Type Performed#

Contrast and textures can be adjusted.

Artifact Evaluated#

Plotting interface. Specifically, evaluating the interfaces for all charts in our test environment: line, bar, table and scatter plot.

Results Summary#

Plotting interface fails to respect a user’s custom changing of contrast and/or textures. The chart forms a “box” that retains it’s default coloring.

Expected Behavior (Pass/Fail)#

  • FAIL - Contrast or textures must provide a way to be adjusted as-needed. Chart must not interfere with or override user’s independent contrast adjustments and chart must adjust accordingly to new settings. Chart textures (such as those used on fills) must be able to be turned on or off according to user preference.

Image or Video of Failure#

A scatter plot is shown. A high contrast filter has been implemented, and the web browser background is black with yellow font. However, the chart space retains it's default color scheme - the contrast change was not applied (fails).
