python 3.x - Seaborn Heatmap Colorbar Label as Percentage -


given heat map:

import numpy np; np.random.seed(0) import seaborn sns; sns.set() uniform_data = np.random.rand(10, 12) ax = sns.heatmap(uniform_data)

how go making color bar values display in percent format? also, if wanted show first , last values on color bar?

thanks in advance!

iterating on solution of @mwaskom, without creating colorbar yourself:

import numpy np import seaborn sns data = np.random.rand(8, 12) ax = sns.heatmap(data, vmin=0, vmax=1) cbar = ax.collections[0].colorbar cbar.set_ticks([0, .2, .75, 1]) cbar.set_ticklabels(['low', '20%', '75%', '100%'])

custom seaborn heatmap color bar labels

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
