matplotlib - Regarding plotting a graph in python using matplolib from the input in text file -


i have written python code generates output in form of text file. numbers in result small(of order of 10^-120) , written in scientific notation in form 1e-120 in output file. wish plot graph using output in text file. how plot graph?

the output in form 1 '\t' 2 stored in text file. wish plot simple x y plot between 2 variables.

i asking here since not find related anywhere , new python. thanks.

assuming values x -> y mapping (e.g. 1d function), plotting these values simple. if have x values in iterable (i.e. list or array or can iterate over) x , y values in iterable y, need import pyplot , do

import matplotlib.pyplot plt plt.plot(x, y) plt.show()

the fact values small not problem. however, sake of presentation might want rescale them multiplying values number, 1e120.

edit: see right need import data. easiest way numpy.loadtxt. assuming data written in file in matrix format (one column x, 1 y), data in same format.

import numpy np import matplotlib.pyplot plt data = np.loadtxt('path/to/file') x,y = data[:, 0], data[:,1] plt.plot(x,y) plt.show()

powershell Start-Process exit code -1073741502 when used with Credential from a windows service environment -

i'm running strange behavior powershell start-process call. here call: $process = start-process ` "c:\somepath\mybinary.exe" ` -passthru ` -credential $defaultcredential ` -wait ` -workingdirectory "c:\somepath" ` -loaduserprofile if ($process.exitcode -ne 0) { #do } this call return exit code - 1073741502 . after quick search, exit code seems related generic error when program not load required dll (aka. status_dll_init_failed ). when run without -credential $credential program runs correctly. in order isolate problem, manually launched some.exe in prompt target credential , runs smoothly. so problem seems come way start-process cmdlet launch process. i found potential solutions problem tried apply no luck : link , link . would have idea of what's going on here ? edit 1: run proc mon monitoring program activities when launched directly or via powershell script. problem seems occur when loading kernelbase
