I have the following code that functions perfectly with the exception that the timing of placing my point annotations and updating the legend does not align to when the point appears on the graph. How do I get them to align?
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.animation import FuncAnimation
from matplotlib import style
import matplotlib.patches as mpatches
style.use('ggplot')
x_data = [1,5,7,9,11,12,14,15,27,29,37,39,45,47,52,53,57,58,61,62,66,80,82,83,84,85,90,91,93,96,98,105,109,110,111,113,114,116,117,120,122,123,127,134,136,138,140,141,144,160,161,162,165,174,176,179,183,184,185,186,190,191,192,193,194,195,199,200,204]
y_data = [50,55,40,30,31,20,21,18,25,21,15,18,20,24,27,30,32,35,37,38,30,11,13,10,10,14,16,18,19,17,14,9,9,4,5,5,6,5,7,3,6,8,10,13,15,12,10,13,8,4,3,5,4,5,7,6,4,8,10,12,10,12,12,12,12,15,17,18,18]
annotations = ['','','Pasted Value','Cut Value','','Pasted Cut Value','','Abnormal Pause','','Abnormal Pause','Out of Order Field Interaction','','','','','','','','','','Window Exit','Window Entry','','Pasted Value','Out of Order Field Interaction','','','Irregular Typing Cadence','','Irregular Typing Cadence','Abnormal Pause','Irregular Typing Cadence','Out of Order Field Interaction','Value Manipulation','','Out of Order Field Interaction','','Value Manipulation','','Value Manipulation','','','','','','','','','Window Exit','Window Entry','Pasted Value','','Value Manipulation','','','Value Manipulation','Value Manipulation','','','','Copied Value','','Frustration - Repeat Paste','Frustration - Repeat Paste','Frustration - Repeat Paste','','','','']

fig, ax = plt.subplots()
ax.set_xlim(0,205)
ax.set_ylim(0,100)

def init():
line.set_data([], [])
return line,
def animate(n):

ax.annotate(annotations[n],(x_data[n],y_data[n]))
updated_score = mpatches.Patch(color='b', label=y_data[n])
plt.legend(handles=[updated_score])
return line,
animation = FuncAnimation(fig, animate, frames=len(x_data), interval=500)
plt.title('A Cool Title')
plt.xlabel('Time in Seconds')
plt.ylabel('Value')
plt.show()
Here is a working replit
Remember that when slicing Pandas doesn't include the last value, therefore in this line plt.plot(x_data[:n+1], y_data[:n+1]) you should add +1 to include the n-th value. I think that solve the lack of timming.
