Overview
|
|
========
|
|
|
|
A number of pre-defined color gradients are available for gempa modules.
|
|
These gradients can be used when displaying color-coded values such as grids,
|
|
spectrograms or heat-maps. The following is an overview of pre-defined
|
|
gradients along with the name of the gradient which can be used in
|
|
configurations. The gradients are grouped into:
|
|
|
|
* :ref:`gradients-fullspectrum`
|
|
* :ref:`gradients-darkyellow`
|
|
* :ref:`gradients-blackandwhite`
|
|
* :ref:`gradients-singlecolor`
|
|
* :ref:`gradients-threecolor`
|
