Speed multiple animations with matplotlib

Question

I am working on a project (Python 3.8, PyQt5, matplotlib, numpy) in which I have two threads:

• data thread : to collect get data and optimize" the collect of data which is between 1 and 5kHz (a line of 256 float)
• gui thread : to display the last data get as fast as possible on the GUI (3 matplotlib figures)

I am also using some animations to make faster the update of data on the screen, using the following pseudocode line:

anim = animation.FuncAnimation(myFigure, updateData, interval=10, blit=False)

I have 3 figures with each 2 subplots:

• To display an image of 256x600 pixels updating only one column with the last data acquire and available
• To display the last data of 256 pixels

So today I have 3 animations, one for each figure.

The pseudo code for the update function is the following one :

def update(self, i):
    # Create fake data (because the data thread is not working for now)
    random = np.random.rand(256)
    
    # Display it on the continuous graph
    dataImg = np.transpose(self.imageInProgress)
    dataImg[:-1] = dataImg[1:]
    dataImg[-1] = random.copy()
    self.imageInProgress = np.transpose(dataImg)
    self.image[0].set_data(self.imageInProgress) # the image list contains all subplots (2D and 1D plots)
    
    # Display it on the line graph
    self.image[1].set_data(range(1, 257), random)
    
    self.countIPS1 += 1
    return

But doing this, I have an update of my total GUI between 5 and 10 times per second.

Is there some parameters of the animation, or anything else, which can upgrade my animation refresh?
