URGENT: How to plot data from text file. Trying to recreate plots from MATLAB

[Pedroski55]

Urgent?? There is lots of info on matplotlib around.

Here is a simple example to get you started.

import numpy
import matplotlib.pyplot as plt
# for locating minor ticks
from matplotlib.ticker import (MultipleLocator, AutoMinorLocator)

def myApp():    
    x = np.arange(0.01, 10.0, 0.01)
    y = x
    z = 2*x    
    fig, ax = plt.subplots(num='My Plot') # name of the output window
    plt.rcParams["figure.figsize"] = [5, 5] # set the size of the output window
    plt.ion() # to make plot non-blocking, i.e. if multiple plots are launched
    ax.plot(x, y, color = 'g', label='y = x')
    ax.plot(x, z, color = 'r', label='y = 2 * x')    
    ax.set_xlim(0, 10)  # increasing time
    ax.set_xlabel('increasing time (s)')
    ax.set_ylabel('voltage (mV)')
    ax.set_title('Crazy stuff ...')
    ax.grid(True)
    ax.legend()
    plt.show()
