Zoom and Pan with React Chart multiple Modifiers

Multiple Zoom Pan Modifiers - React

Overview

This example demonstrates how to create a high-performance, interactive chart in a React environment using SciChart.js. The chart showcases multiple zoom and pan behaviors including rubber-band zoom, pinch zoom, mouse-wheel zoom, and double-click zoom-to-fit. Data is dynamically generated via Fourier series, and the visual display is enriched with annotations to guide user interactions.

Technical Implementation

The implementation leverages the <SciChartReact/> component which integrates SciChart.js into React applications. The core of the example is defined in the drawExample function where a SciChartSurface is instantiated with configurable numeric axes and real-time series data. Multiple chart modifiers are added: the RubberBandXyZoomModifier (triggered on the right mouse button) applies an elastic easing function for smooth zoom animations, while the ZoomPanModifier (with pinch zoom enabled), MouseWheelZoomModifier, and ZoomExtentsModifier further enhance user interactivity. Developers can find more details on this approach in the React Charts with SciChart.js guide and explore zoom and pan specifics via the SciChart.js Zooming and Panning documentation.

Features and Capabilities

The chart features advanced zooming and panning capabilities that include rubber-band and pinch zoom along with mouse-wheel interactions and double-click zoom extents. It also incorporates animated transitions using an elastic easing function for a seamless user experience. Annotations, both text and native, are implemented to provide contextual instructions and enhance the user interface. Learn more about these advanced features on the SciChart.js Demo for Multiple Modifiers.

Integration and Best Practices

The example is implemented as a React component, using the <SciChartReact/> wrapper to initialize and render the chart. This encapsulates the chart creation process and allows for efficient resource management. Developers are encouraged to follow best practices for memory management by properly disposing of the SciChartSurface when unmounting components.
