Frequently Asked Questions
What types of numbers can I plot?
You can plot any real number including positive integers, negative integers, decimals, fractions (as decimals), and zero. The tool automatically handles proper scaling and positioning for all number types.
How do I set the appropriate range?
The tool can automatically adjust the range based on your input numbers, or you can manually set minimum and maximum values. For best results, choose a range that provides adequate space around your plotted points for clear visualization.
Can I customize the appearance?
Yes! You can customize point sizes, line thickness, show/hide grid marks and numbers, adjust the range, and each point gets a unique color automatically. The tool provides extensive customization options for professional-looking results.
How do I export the visualization?
Click the "Download PNG" button to save your number line as a high-quality image file. The exported image maintains the same quality and formatting as displayed on screen, perfect for presentations and documents.
Is this suitable for classroom use?
Absolutely! The tool is designed with educators in mind. It creates clear, professional visualizations perfect for worksheets, presentations, and interactive lessons. The preset examples help you get started quickly with common educational scenarios.
What's the maximum number of points I can plot?
While there's no strict limit, for optimal visualization clarity, we recommend plotting up to 20-30 points at once. Too many points can make the visualization cluttered. For larger datasets, consider grouping or filtering your data first.
