![]() There are two basic types of colormaps included in lors: The Normalize instance provides the method to scale the data in the ScalarMappable to the range while the Colormap maps the range to N RGBA colors where N is the size of the colormap. This is what lets the disparate objects like Collection returned by poclor() or scatter() and Image returned by imshow() use the same framework for colormaps.Įach ScalarMappable instance is associated with a Normalize instance and a Colormap instance. they are generally not the primary class of the object. ![]() Mixin classes provide common functionality, but are not designed to "stand on there own" i.e. Objects generated by functions like pcolor(), contourf(), scatter(), and imshow() subclass ScalarMappable as a mixin class. This mapping occurs using a couple of different classes: The class is the basis for all colormaps which are just mappings from a scalar value to an RGBA value. an RGB or RGBA vector like with each channel scaled in range.a string representation of a float, like ‘0.4’, indicating gray on a 0-1 scale. ![]() a letter from the set ‘rgbcmykw’ (e.g.The various arguments that ColorConverter.to_rgba() can take are: This RGBA representation is the one used by matplotlib internally. ![]() This is done using the method _rgba() which converts the color to an RGBA representation, which is a vector of four values from 0-1 specify the Red, Blue, Green, and Alpha channels where 1 is fully-saturated (for RGB) or fully opaque (for Alpha). ) accept the color in a variety of formats. Most functions that take color arguments (e.g. Color and colormap basics Specifying colors in matplotlib show () for cmap_category, cmap_list in cmaps. text ( x_text, y_text, name, va = 'center', ha = 'right', fontsize = 10 ) # Turn off *all* ticks
