I'm looking for a good circular/cyclic colormap to represent phase angle information (where the values are restricted to the range [0, 2π] and where 0 and 2π represent the same phase angle).

papuc is a small library designed for creating perceptually uniform color mappings of vector fields where vector orientations/phase angles are mapped onto hue and vector …

Below is example code for a 3d plot with the colormap corresponding to the x values. The facecolors argument is used to alter the colormap to your liking. Note that its value is acquired …

Cyclic: change in lightness of two different colors that meet in the middle and beginning/end at an unsaturated color; should be used for values that wrap around at the endpoints, such as …

Aug 13, 2015 · You can use the c keyword in the scatter command, to tell it how to color the points. You don't need to set zdir, as that is for when you are plotting a 2d set. As @Lenford …

Choosing colormaps for surfaces in 3D has the additional requirement of enhancing the geometric visualization along with defining functional values. S3Dlib provides multiple easy-to-use …

Repository with Python and MATLAB code for coloring optical vortex and optical fork images using cyclic colormaps, enhancing readability for angles, days, moon phases, and seasons.

The following demonstrate the construction and application of custom color mapping using the Color Map Utilities along with surface shading and highlighting. In most of the following …

Creating a cyclic colormap that avoids visual distortions for phase angle plots in Python can be achieved by using perceptually uniform colormaps. These colormaps ensure that the …

Dec 14, 2024 · The colormaps are collections of colors used to map data values to colors. They are very useful for visualizing data on a gradient, such as heatmaps or surface plots.
