Pinch-to-Zoom in Stock Charts — JS Chart Tips

March 5th, 2025 by AnyChart Team

A stock chart with pinch-to-zoom functionality and JavaScript codeStock charts are designed to handle large volumes of time-based data, and smooth navigation is key to working with them effectively. One common need is zooming — whether to focus on a specific time range in greater detail or to get a broader view of the data.

In our JavaScript stock charts, zooming works out of the box through the scroller element, which appears by default as the main navigational UI control, making it easy to adjust the visible range on the go. For even greater flexibility, the range selection UI provides extra tools like preset time period buttons and date input fields. You can also activate zooming via mouse wheel scrolling with the zoomOnMouseWheel() method, which corresponds to the two-finger swipe gesture on touchpads and trackpads.

Pinch-to-zoom is another intuitive zooming option. It allows users to zoom in and out naturally on mobile and touch devices by moving two fingers farther apart or closer together. This is also easy to implement — and it is exactly what we cover in this edition of JS Chart Tips. Learn how to add pinch-to-zoom to your JavaScript stock chart!
