JBChartView
JBChartView is an iOS charting library and data visualization framework used to render interactive line and bar graphs. It provides reusable user interface components for displaying numerical data series through smooth line curves and grouped or horizontal bar charts.
The framework is distinguished by its ability to morph bars and lines between different data states, creating visual transitions that represent changes in underlying data models. It also includes interaction handling that detects user selections on specific data points and returns the associated model instances.
The library covers axis configuration and scaling, visual styling with gradient fills, and data point annotations such as tooltips and markers. To maintain performance during scrolling, the system employs viewport-aware element caching to keep only visible graph elements in memory.
Features
