pandas column data as marker in plot?

Question

the code below plots the data with the marker as a green spot. BUT I want the marker to be the actual value of y. So instead of the green dots the marker would be 10, 22.5, 43.34. Anyone done this please?

import numpy as np
import matplotlib.pyplot as plt


x = [ 10,20,30] 
y = [ 10,22.5 ,43.34 ]

x_new = 100
y_new = np.interp(x_new, x, y)

print(y_new)

plt.plot(x, y, "og-");

plt.show()

I think you are looking for annotate instead:

plt.plot(x, y, "og-",markersize=40);

for xx,yy in zip(x,y):
    plt.annotate(f'{yy}', (xx, yy), va='center',ha='center', color='w')

Output:

thank you so much AGAIN!!! I didn't even know annotate existed. I REALLY have to read the docs more. Thanks again. I have to mod the answer as I am using plt.subplots(nrows=2, ncols=1) and .plot(ax=axes[0] ) thanks again for such wonderful help
