# Digitize Graphs & Plots Online with AI

> Digitizing published scientific plots, academic papers, and benchmark charts used to require tedious manual clicking on every individual coordinate. FastToChart automates graph digitization with computer vision, extracting continuous curves and scatter points in seconds.

## How It Works

1. Upload your plot screenshot, scanned research figure, or PDF chart.
2. Computer vision detects axes, calibrated ranges, and samples data points.
3. Inspect the extracted coordinates and download as CSV or Excel data.

## Automated Curve Sampling vs. Manual Clicking

Legacy plot digitizer software requires you to manually define X1, X2, Y1, Y2 calibration points, adjust color filters, and click hundreds of coordinates by hand. FastToChart replaces this entire manual process with intelligent neural perception.

For continuous mathematical curves and oscilloscope traces, our engine samples 40 to 80 points across the curve, tracking every peak, trough, and inflection point.

## Scatter Plots and Bubble Clusters

Scatter plots are extracted with both X and Y coordinates preserved for each dot, preventing dimensional collapse. For bubble charts, the third variable encoded by marker radius is extracted into a dedicated 'size' column.

## Logarithmic and Dual Axis Support

Scientific and financial graphs frequently use logarithmic Y-axes (powers of 10) or dual Y-axes with different measurement units. FastToChart detects log scales and maps series to their corresponding primary or secondary axis.

## Frequently Asked Questions

### Can I digitize scanned papers from Google Scholar or arXiv?

Yes. Simply take a screenshot of the figure or upload the PDF page. FastToChart reads plots directly from academic publications.

### How does it handle noisy backgrounds or watermarks?

Multimodal models separate visual noise, watermarks, and gridlines from the actual data strokes with high fidelity.

### What coordinate export formats are available?

You can download CSV, Excel (.xlsx), or copy coordinates straight to your clipboard.
