Two Graph

🟨📊 Technique Card: Creating Graphs with 2Graph (practical)

Big Idea: Graphs help us see patterns in data. With 2Graph on Purple Mash, you can easily turn your survey or project data into colourful, clear charts.
Useful for: Showing food mile distances, favourite foods, travel surveys, and more!

🧠 What is 2Graph?

2Graph is a simple tool on Purple Mash that lets you:

  • Type in your data
  • Choose a type of graph (bar, scatter, line, etc.)
  • Label your graph and share or print it

🧪 Step-by-Step: Make a Graph in 2Graph

  1. Log in to Purple Mash with your school account.

  2. Go to the Tools tab.

  3. Find and click on 2Graph (under Maths or Data Handling).

  4. You’ll see two columns:

  5. Label (what each bar or part represents)
  6. Value (the number for each item)

📝 Example: How Children Travel to School

Label Value
Walk 72
Bike 38
Car 56
Bus 44

👣 Type each travel type into the Label column and the number of children in the Value column.

🎨 Choose Your Graph Type

At the top, click one of the graph icons to switch between:

  • Bar chart (great for comparing)
  • Scatter graph (great for showing connections)
  • Line graph (good for changes over time)

🧷 Add a Title and Labels

  1. Click the Title box and type a clear title, like:
    “How Our Class Gets to School”

  2. You can also add x-axis and y-axis labels if using a bar or line graph.

💾 Save or Share

  • Click the Purple Disk icon to save your graph in your folder.
  • Or use the Export icon to export your graph as a CSV file or a PNG image file.

Tip

Having a PNG image file of your graphs is great - you can then use them in PowerPoint presentations, websites and more! 🫶

🧠 Top Tips

  • Always give your graph a title!
