How to Format and Label Graphs Professionally in the IB Math IA

Example:

x-axis: Time (s)
y-axis: Temperature (°C)

RevisionDojo’s Axis Label Generator creates clean, standardized axis labels in IB-approved formats.

Step 3: Add Descriptive Titles

Titles should tell the examiner exactly what the graph shows — not just the variables.

Weak: “Graph 1”
Strong: “Graph 1: Temperature Decay of Water Over Time”

RevisionDojo’s Title Formatter helps you generate professional, descriptive graph titles automatically.

Step 4: Maintain Consistent Formatting

All graphs in your IA should look cohesive.
Use consistent:

• Colors and fonts
• Line thicknesses
• Marker shapes and sizes

RevisionDojo’s Visual Style Guide standardizes all visual elements for a uniform professional look.

Step 5: Include Captions and Figure Numbers

Every graph must have a numbered caption directly beneath it:

Example:

Figure 2. Exponential model of temperature decay with best-fit line (R² = 0.982).

RevisionDojo’s Caption Generator formats figure labels perfectly for IB submission standards.

Step 6: Annotate Key Features

Examiners love graphs that show awareness — highlight points of interest such as maxima, intersections, or anomalies.

Example:

“The turning point at (3.2, 45.6) represents the maximum height of the projectile.”

RevisionDojo’s Annotation Tool lets you mark and label critical coordinates directly on graphs with precision.

Step 7: Use Appropriate Scales and Gridlines

Incorrect or inconsistent scales can distort interpretation.
Keep increments uniform and use gridlines only if they improve readability.

RevisionDojo’s Scale Checker ensures proportional scaling for accurate mathematical interpretation.

Step 8: Avoid Overcrowding

Don’t overload graphs with multiple datasets unless necessary.
If you compare several models, use color contrast and separate legends.

Example:

“The red curve shows the theoretical model; blue dots represent experimental data.”

RevisionDojo’s Clarity Enhancer helps declutter visuals for examiner-friendly simplicity.

Step 9: Reference Each Graph in the Text

Always mention graphs in your discussion so they have purpose.

Example:

“As shown in Figure 3, the curve follows an exponential pattern consistent with the model T(t) = T₀e⁻ᵏᵗ.”

RevisionDojo’s Reference Template provides sentence starters for referring to visuals professionally.

Step 10: Review Graphs With the IB Visual Standards Checklist

Before submission, check that every graph meets IB requirements:

• Clearly labeled axes and units
• Descriptive title and caption
• Consistent formatting
• Readable legends and fonts
• Direct link to written analysis

RevisionDojo’s Visual Standards Checklist ensures every graph meets examiner expectations perfectly.

Frequently Asked Questions

1. Can I use color graphs in my IA?
Yes, color graphs are allowed — just make sure they’re readable when printed in black and white.

2. Do graphs count toward the word limit?
No, but captions and discussion of graphs do count.

3. Should I include raw data graphs?
Include at least one raw data visualization if your IA involves data analysis; it shows the origin of your modeling process.

Final Thoughts

Graphs are where your mathematics becomes visible.
Clear, well-formatted visuals not only improve communication but also demonstrate professionalism, precision, and understanding — everything examiners look for.
