Last weeks thread here

Welcome to this week’s casual kōrero thread!

This post will be pinned in this community so you can always find it, and will stay for about a week until replaced by the next one.

It’s for talking about anything that might not justify a full post. For example:

  • Something interesting that happened to you
  • Something humourous that happened to you
  • Something frustrating that happened to you
  • A quick question
  • A request for recommendations
  • Pictures of your pet
  • A picture of a cloud that kind of looks like an elephant
  • Anything else, there are no rules (except the rule)

So how’s it going?

    You could do this with python and a couple of libraries. This is just an example, but you could import the data from a DB or use a CSV file.

    import matplotlib.pyplot as plt
    import numpy as np
    
    # Pie chart data
    labels = ['Category A', 'Category B', 'Category C', 'Category D', 'Category E']
    sizes = [30, 25, 20, 15, 10]
    colors = ['#ff9999','#66b3ff','#99ff99','#ffcc99','#c2c2f0']
    
    # Pie chart
    plt.figure(figsize=(8, 8))
    plt.pie(sizes, labels=labels, colors=colors, autopct='%1.1f%%', startangle=140)
    plt.title('Sample Pie Chart')
    plt.axis('equal') # Equal aspect ratio ensures that pie is drawn as a circle.
    plt.show()
    
    # Histogram data
    data = np.random.normal(0, 1, 1000) # Generate 1000 random data points with a normal distribution
    
    # Histogram
    plt.figure(figsize=(10, 6))
    plt.hist(data, bins=30, color='#66b3ff', edgecolor='black')
    plt.title('Sample Histogram')
    plt.xlabel('Value')
    plt.ylabel('Frequency')
    plt.show()

      Ooh thanks! I’ll definitely have a play with this. What’s the step before this? Is it as simple as installing python, putting the code in somefile.py, then running it?

        Yep, if you are running any type of Linux python is already installed.

        I always have a path in my python files to allow for direct running rather than calling python first. This only works on Linux.

        If you put
        #!/usr/bin/env python3
        as the very first line, you can make the file executable and it will just run

        otherwise you will have to call python first, e.g. python yourFile.py

          Awesome, thanks! I’ll have a play with this over the weekend.
