python - How to overlay plots from different cells? -


in 1 of cells in notebook, plotted with

myplot = plt.figure() plt.plot(x,y)

now, in different cell, i'd plot exact same figure again, add new plots on top of (similar happens 2 consecutive calls plt.plot()). tried adding following in new cell:

myplot plt.plot(xnew,ynew)

however, thing in new cell new plot, without former one.

how can 1 achieve this?

there 2 ways tackle this.

a. object-oriented approach

use object-oriented approach, i.e. keep handles figure and/or axes , reuse them in later cells.

import matplotlib.pyplot plt %matplotlib inline  fig, ax=plt.subplots() ax.plot([1,2,3])

then in later cell, 

ax.plot([4,5,6])

suggested reading:

b. keep figure in pyplot

the other option tell matplotlib inline backend keep figures open @ end of cell. 

import matplotlib.pyplot plt %matplotlib inline  %config inlinebackend.close_figures=false # keep figures open in pyplot  plt.plot([1,2,3])

then in later cell

plt.plot([4,5,6])

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
