Weibull Non-exceedance plot (axis 'x')

I am working on the Weibull distribution. I've estimated the parameters for my data and I've got the probability plot. As seen in the code bellow, on the probability plot I have 'pasted' the parameter values that I obtained.

But, is there any other way to attach them to the plot?

Another question is: how can I get a plot with the probability of non-exceedance on axis 'x' and the variable on axis 'y', which, in turn, includes the weibull adjustment with the three parameters. The plot I'm looking for is like this (or similar).

Weibull Non-exceedance curve

The code in python I wrote is the next:

from matplotlib import pyplot as plt  import pandas as pd  import numpy as np  plt.style.use('classic')  %matplotlib inline  import seaborn as sns  from scipy.stats import exponweib, probplot as pp, weibull_min  import probscale  from probscale.viz import probplot as pp_scale, plot_pos  import statsmodels.distributions  from scipy.optimize import fmin  import statsmodels.api as sm    datos = pd.read_csv('01_ATN_ACCE_his_1985_2005.csv')  Hs = datos['Hs']  plt.hist(Hs, density = True, alpha = 0.5, bins=45)  shape, loc, scale = weibull_min.fit(Hs)  x = np.linspace(Hs.min(), Hs.max(), 500)  plt.plot(x, weibull_min(shape, loc, scale).pdf(x))  plt.xlabel("Hs (m)")  plt.ylabel("%")  plt.title("Ajuste Weibull sobre Hs")  fig, ax= plt.subplots(figsize=(12,6))  pp(Hs, dist = weibull_min(shape, loc, scale), fit=True, plot=ax, rvalue=True)  plt.text(0.5,7,'A=', fontsize=14)  plt.text(0.7,7,'{0:.2f}'.format(scale), fontsize=14)  plt.text(0.5, 6.5, 'B=', fontsize=14)  plt.text(0.7,6.5,'{0:.2f}'.format(loc), fontsize=14)  plt.text(0.5, 6, 'C=', fontsize=14)  plt.text(0.7,6,'{0:.2f}'.format(shape), fontsize=14)  ax.get_children()[2].set_fontsize(14)   ax.get_children()[2].set_position((0.5,5.5))
