Research direction

Launch a VISOR session and inspect the existing legends panel and state-file workflow first. Implementing the requested orientation, palette, levels, interpolation, undefined-value color, and persistence options is done when they work for a colored variable and reload correctly from a saved state file.

User Story Description

The MVP list contained the legend panel. That panel for the MVP had minimal functionality. New functionalities need to be added, in particular:

  • control orientation of the legend (horizontal / vertical)
  • color palette (select from a list of palettes. Note: usually tools show both the name and a schema of the palette)
  • control number of palette levels. You can control the number of levels, value at each level and exact color
  • type of interpolation (linear vs log) between palette levels
  • color to use for undefined value. The user should set from the color wheel or RGB
  • pick the interpolation type for the palette: continuous, banded, constant
Acceptance Criteria

Launch a VISOR session. Color one part by a variable. In the legends panel, all the new functionalities are available and work.

Save a state file. Launch a new VISOR session. Load the state file. Verify that all the legend advanced options are stored correctly.
