QPlot: luts.get

≡

luts.get

Retrieve a colormap.

Call signature:

luts.get(name, N=None, reverse=False)

Help text:

cm = luts.get(name) retrieves the named colormap.

Optional argument N specifies the number of colors to return. Default is dependent on the particular map.

Optional argument reverse specifies that the order of the colors should be reversed.

Use luts.families, luts.family, luts.names to explore available colormaps.

See also luts.set.

The full collection of available colormaps is shown here.

Example:

import qplot as qp

import numpy as np

qp.figure('luts.get', 3, 3)

xx = np.tile(np.arange(11), (11,1))

yy = np.transpose(xx)

zz = np.cos(xx) + np.sin(yy)

cc = qp.luts.get("qpjet")

qp.lut(cc)

qp.imsc(zz, xx=xx, yy=yy, c0=-2, c1=2)

qp.xaxis('X', [0,5,10], y=-.5, lim=[-.5, 10.5])

qp.yaxis('Y', [0,5,10], x=-.5, lim=[-.5, 10.5])

qp.cbar(width=10)
