I'm currently trying to plot some data that is being generated realtime from a simulation, this portion of code is a simplified version of what I have right now. It works but it is incredibly slow. Are there any tricks or other methods to speed this up.

My simplified code:

import matplotlib.pyplot as pltimport numpy as npimport timeplt.ion()class plotting_class():    def __init__(self):        self.x = []        self.y = []        self.fig, self.ax = plt.subplots()    def plotting(self,i):        # for i in range(20):        self.x.append(i)        self.y.append(5*i)        self.ax.plot(self.x, self.y, 'b')        self.fig.canvas.flush_events()plot_obj = plotting_class()for i in range(20):    plot_obj.plotting(i)    time.sleep(1) # just to see the additions to the plot    if i ==1:        plt.show()

Dynamically plotting data real time quickly

Is this really something related to Microsoft Dynamics 365? If so, which D365 app are you using and what you're doing there with Matplotlib?

I suspect you came to a wrong site by mistake.
