Quick answers to common questions
What types of plots can I create?
You can create line plots, scatter plots, bar charts, histograms, and more. Simply enter your data and the tool generates a professional mathematical visualization.
How do I enter my data?
You can enter data as comma-separated values, tab-separated values, or copy-paste from spreadsheets. The tool automatically parses your data and suggests appropriate plot types.
Can I customize the plot appearance?
Yes! You can adjust colors, labels, titles, axis ranges, and line styles. All changes are reflected in real-time in the preview.
Can I export the plot?
Yes! You can download your plot as a high-resolution PNG image or SVG file. You can also copy the data URL to embed the plot directly in HTML.
Is my data private?
Absolutely. All plotting happens locally in your browser. Your data is never sent to any server.

About This Tool
Sometimes you need to visualize a mathematical function—see what it looks like, find roots or intersections. This tool plots functions in real-time as you type. Supports basic functions (sin, cos, exp, log, etc.), constants (pi, e), and arithmetic. Great for students learning math or anyone who needs to quickly visualize a function.
Technical Details
Algorithm
Function evaluation: for each pixel's x-coordinate, calculate y by evaluating the function. Connect points to form the curve. Grid lines and axes are drawn for reference. Zooming adjusts the x/y range and re-renders. Functions are parsed using JavaScript's math evaluation (safe subset). Smooth curves even for complex functions by sampling enough points.
Privacy Commitment
🔒 **Privacy First**: Unlike server-based tools, AI-TOL processes everything locally in your browser - your data never leaves your device. No uploads, no tracking, completely private.
