A similar issue was discussed in a closed thread where the solution involved setting the font for matplotlib to display Chinese characters correctly. You can use the following code snippet to set the font to 'SimHei', which should be placed before generating the charts:

import matplotlib.pyplot as plt

# Set the font for matplotlib
plt.rcParams['font.sans-serif'] = ['SimHei']  # Use 'SimHei' font to display Chinese characters
plt.rcParams['axes.unicode_minus'] = False  # Ensure the minus sign is displayed correctly

Make sure to include this code in your script before any chart generation code. This should help in displaying Chinese characters correctly in your charts ^[1].

where can i find the code generating the charts. agent.chat(prompt) already output the charts png image, i can`t modify the image title

[dosubot[bot]]

To modify the image title for the charts generated by agent.chat(prompt), you should look into the generate_matplotlib_code method within the CodeGenerator class. This method is responsible for generating the code that creates the charts using Matplotlib. Specifically, the line that sets the title of the plot is:

if title:
    code += f"plt.title('''{title}''')\n"

You can modify this line to change how the title is set or to use a different title ^[1].
