Scalarmappable

Edit and run, scalarmappable. The following scalarmappable shows various ways of generating and working with colormaps and functions like pcolormesh and contourf. Most functions that take color arguments e.

We are creating manual ScalarMappable instances in some cases where colorbar creation is detached from the plotting event.

Builtin colormaps, colormap handling utilities, and the ScalarMappable mixin. Colormap reference for a list of builtin colormaps. Creating Colormaps in Matplotlib for examples of how to make colormaps. Choosing Colormaps in Matplotlib an in-depth discussion of choosing colormaps. Colormap normalization for more details about data normalization. Bases: Mapping. The universal registry instance is matplotlib. There should be no need for users to instantiate ColormapRegistry themselves. Read access uses a dict-like interface mapping names to Colormap s:. Returned Colormap s are copies, so that their modification does not change the global definition of the colormap. Additional colormaps can be added via ColormapRegistry. The colormap name can then be used as a string argument to any cmap parameter in Matplotlib.

This is done using the method matplotlib. These examples were dervied from Scalarmappable which has some great examples of various colormaps, scalarmappable.

This module provides a large set of colormaps, functions for registering new colormaps and for getting a colormap by name, and a mixin class for adding color mapping functionality. This is a mixin class to support scalar data to RGBA mapping. Normalize instance. The normalizing object which scales data, typically into the interval [0, 1]. Autoscale the scalar limits on the norm instance using the current array, changing only limits that are None.

Enter search terms or a module, class or function name. Bases: matplotlib. It is not intended to be instantiated directly; instead, use colorbar or colorbar to make your colorbar. Add the lines from a non-filled ContourSet to the colorbar. Remove this colorbar from the figure. Destroy and rebuild the colorbar. This is intended to become obsolete, and will probably be deprecated and then removed. It is not called when the pyplot. This is meant to be called when the image or contour plot to which this colorbar belongs is changed.

Scalarmappable

Bases: object. Typically, Colormap instances are used to convert data values floats from the interval [0, 1] to the RGBA color that the respective Colormap represents. For scaling of data into the [0, 1] interval see matplotlib. Subclasses of matplotlib. The data value s to convert to RGBA. For floats, X should be in the interval [0.

In order to create a colorbar without an attached image, one can instead use a ScalarMappable with no associated data. You switched accounts on another tab or window. Normalize instance that is used to normalize the ScalarMappable values to the range Found a bug? Normalize instance The normalizing object which scales data, typically into the interval [0, 1]. More information can be found in the matplotlib. Navigation index modules next previous Matplotlib 1. Note that you do not have to register colormaps to use them, it's just a convenience. In [20]:. The matplotlib. Changed in an element-wise comparison of the color array is made, however, with ScalarMappable.
