Show discrete/continuous color legends for
- Well log data
- Surface properties
- Grid properties including blocked well grid values
-
Apply color table to specific layers
- Only show color legend for visualized layers
-
Use (read-only) library of stock color tables
- Geological and geophysical domains RMS color table, Epos color table
- Other (eg. d3 library)
Color table features:
-
Allow variable number of colors (eg. 3 colors for seismic)
-
Use different sampling methods
- Sample with breakpoints (eg. narrow bands)
- Interpolation
- Linear (default)
- Logarithmic
- Nearest (eg. contours)
- Continuous/discrete according to data
- Scalar data Range (often termed min, max)
- Nice to have: Dynamic sampling according to the distribution of data (cf. BLA Dashboard)
-
Create custom color tables
- Customize color scale (ie. add, delete, change color )
- Edit, delete, create breakpoints
- Copy and modify existing color scale
- Change sampling of color table
- Nice to have: Pick color from screen
-
Mapping from scalar data to color
- Scalar data Range (often termed min, max)
- UNDEF or NaN (Not a Number) will be no color (transparent)
-
Discrete code mapping table
-
Nice to have: Transparency (what is the complexity needed)
- Simple transparency, on transparency for all colors
- Alternatively transparency varying linearly according to user defined points along colors (like RMS seismic color and transparency)
-
Schema for color tables format
- Reduce padding between items to reduce space
- Auto close sections when opening other sections
-
Open interpolation settings from "..." button on legend- not good for printing - Open color scale editing from "..." button on scale
-
Show drop down icon on legend to indicate drop down menu- enough to change the mouse cursor to indicate - Overlap between color scales and labels is masking names of color scales in selection list
- Shrink color scale
- Label eliding
- Place label right of scale
- Color scale selector: Align label vertically with color scales in the list
- Too many clicks to open drawers in accordion
- Collapse some drawers
- Allow opening color settings in a drawer instead of dropping down from legend
- Create storybook example
- Add highlighting when hovering the legend to indicate that it is editable
- Add tooltip
