LightningChart Python - Ultra-High-Performance Python Charts
LightningChart Python is a GPU-accelerated, WebGL-powered data visualization library for Python, designed to deliver exceptional performance and real-time responsiveness when creating charts using massive static or streaming datasets.
Watch the showcase video below:
Key Features
- High-performance rendering: Leverages GPU acceleration and WebGL rendering for smooth interactivity and high refresh rates, even with millions of data points.
- 2D & 3D charts: Support for an extensive range of visualization types, including line, scatter, heatmap, area, box, figure, spline, step, point-line, polar, bar, pre, funnel, pyramid, map, treemap, parallel coordinate, gauge and 3D charts including line, scatter, surface, scrolling surface, mesh model and box.
- Real-time streaming: Built to handle real-time updates efficiently for dynamic dashboards and monitoring solutions.
- Seamless integration: Works with familiar Python tools: NumPy, Pandas, and GUI frameworks like PyQt, as well as Jupyter notebooks and standalone scripts.
- Licensing options:
- Data Scientist (free/premium): Tailored for personal projects, including scripting and notebook-based workflows. Includes a 7-day free trial of premium features.
- Software Developer: Per-seat, perpetual license designed for embedding charts in commercial, distributable software.
Getting Started
Installation
pip install lightningchart
Basic Example
import lightningchart as lc
import random
lc.set_license("your-license-key")
x = list(range(250))
y = [random.random() for _ in x]
chart = lc.ChartXY(theme=lc.Themes.Light, title="Line Chart")
chart.add_line_series().add(x, y)
chart.open()
About Performance:
