.. py:function:: draw_probability(list)

   Generate a bar plot visualizing the probabilities of a quantum state.

   The function takes a dictionary containing quantum state keys and their corresponding
   probabilities, normalizes the probabilities, and plots them using a bar chart.

   Args:
       probability_dict (dict): 
           A dictionary where keys represent the quantum states and
           values represent their respective probabilities.

   Returns:
       None: 
           This function does not return a value. It plots the probabilities directly.

   Notes:
       The bar plot uses the Chinese font 'SimHei' and ensures that negative symbols are
       not displayed in the axes.
       The x-axis represents the quantum states, while the y-axis represents the
       probabilities.
       The function includes a grid on the y-axis for better readability.


.. py:function:: draw_probability_dict(prob_dict)

   Generate a bar plot representing the probabilities of a quantum state from a given dictionary.

   Args:
       prob_dict (dict): 
           A dictionary where keys are quantum state labels and values are their corresponding probabilities.

   Returns:
       None: 
           This function does not return a value; it displays a bar plot.

   The function configures Matplotlib to use SimHei font for better readability in Chinese characters.
   It filters out non-positive probabilities, calculates normalized probabilities, and then plots them as a bar chart.
   The plot includes a grid and labeled axes for clarity.
   This utility is intended for use within the pyQPanda package, which is designed for programming quantum computers.
