I'm solving the optimization problem by different methods (for study).
The idea is written bellow:
instance = class_with_diff_methods()
instance.create_some_func()
instance.optimization_method_one()
instance.create_data_for_plot()
instance.display()
instance.optimization_method_two()
instance.create_data_for_plot()
instance.display()
So I wanted to add the new data iteratively, without saving and I implemented my idea this way: `
import matplotlib.pyplot as plt
def display(self):
if not self.__plot_exists:
self.figure = plt.figure()
plt.scatter( self.data[0], self.data[1])
plt.plot( self.data[0], self.appdata)
self.figure.show()
self.__plot_exists = True
else:
plt.plot( self.data[0], self.appdata)
plt.show( block=False)`
This works, but the problem is that I don't really understand, why I even need (it necessary) using "self.figure" in the first part of the code and why I should use "plt.show()" instead of just "self.figure.show" at the last line.
I would be grateful for links, that will help me clearly understand how this works.
The plt.show() method is native from matplotlib, it is what launches the GUI. Check out their documentation if you would like to know about these types of things:
