# BRING YOUR DATA TO LIFE

## DRAG-RECALCULATE

Our "Drag-Recalculate" feature (patented) brings you the best user experience ever: by allowing you to effectively extract, integrate, or even exchange data among multiple charts, ECharts opens you up every opportunity for data mining and integration.

## BIG DATA MODE

Got tens of millions of data to present? And once again professional statistical tools (e.g. MATLAB) seem like the only option left? Nope, not anymore! Despite rich interactivity, ECharts can still plot up to 200,000 data points on a Cartesian chart (line, column, scatter, candlestick) in the blink of an eye.

## SCALE ROAMING

The colors in the Cartesian chart (like map or scatter) will help you to classify data at first glance. But how to focus on data that matters after the initial analysis? With our "Scale Roaming" feature, you can turn off other scales and focus on the scale you are interested in with just a click.
