python - Colorbars close to subplots -


how can put colorbars beside each colormap in subplot? simplified version of real code here shows problem. can see colorbars @ bottom right , making last plot smaller. 

from matplotlib import pyplot plt import numpy np def plots():     fig,ax=plt.subplots(2,2)     in range(2):             rho_mat,c_mat=np.random.uniform(size=(50,50)),np.random.uniform(size=(50,50))         ax[0,i].set_title(r"$\rho_{x,y}$")                 p=ax[0,i].imshow(np.fliplr(rho_mat).t,extent=[0.,1,0.,1],vmin=0,vmax=1, interpolation='none')             ax[0,i].set_xlabel(r'$\epsilon_1$')         ax[0,i].set_ylabel(r'$\epsilon_2$')         fig.colorbar(p, shrink=0.5)         ax[1,i].set_title(r"$c_{x,y}$")         p2=ax[1,i].imshow(np.fliplr(c_mat).t,extent=[0.,1,0.,1],vmin=0,vmax=1, interpolation='none')         ax[1,i].set_xlabel(r'$\epsilon_1$')         ax[1,i].set_ylabel(r'$\epsilon_2$')         fig.colorbar(p2, shrink=0.5)         plt.tight_layout()     plt.show() plots()

enter image description here

the colorbar method has optional keyword argument allows specify axes associated with.

in code change call colorbar this:

fig.colorbar(p, ax=ax[0,i], shrink=0.5) fig.colorbar(p2, ax=ax[1,i],  shrink=0.5)

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
