LightningChart Ultimate SDK
One of the fastest measurement, engineering and research data visualization software development kits for .NET and Windows. LightningChart Ultimate is an entirely GPU accelerated (Direct3D) and performance optimized data visualization control for presenting masses of data in 2D, 3D and polar views. LightningChart Ultimate is especially designed for professional measurement applications, such as data acquisition, PC-based oscilloscopes, vibration measurement, signal analyzers, scientific research, medical and other real-time measurement and signal monitoring applications. Being optimized for high-speed sampled signal data handling with innovative techniques, it is able to handle incredible data rates, where other chart/graph controls get delayed, frozen or crash. 3D views allow high-quality dynamic graphics with many series types. 3D surfaces can be presented with plentitude of height-coloring, wire-framing, contouring and lighting options. Surfaces can be presented in exceptional high detail, with over 2000x2000 surface points.

LightningChart Ultimate SDK consists of the following components:

  • LightningChart Ultimate
  • ChartManager
  • SignalGenerator
  • SignalReader

LightningChart Ultimate
By utilizing the power of modern display adapters and extreme code optimization, the screen resolution can be very high even with the most demanding real-time measurements. There are many horizontal scrolling modes available, providing an ideal and smooth scrolling effect for every scenario. The data handling capacity is up to hundreds of millions of new data points / sec.

LightningChart Ultimate allows using many different series types, signal tracking cursors and signal markers. Data handling capacity and performance is excellent also in signal review and analysis applications. For that purpose, it has built-in customizable scroll bars, with 64-bit value range for direct usage as sample indexing in long high speed measurements. Appearance is fully customizable providing a very modern user interface.

LightningChart has high-capacity 3D surface and waterfall series. Series can be colored by their height information, with height gradient or solid color intervals. Contouring and wire-framing can be applied over filling, with various styles. With SurfaceMeshSeries3D, it’s possible to make any shape 3D figure.

In addition to these advanced features, LightningChart Ultimate provides regular data visualizations, like stock candle-stick series, bars, polar lines, polar areas, 3D bars and 3D point-lines.

Key properties

  • Draws huge amounts of measured data as graphs in real-time, very smoothly, up to hundreds of millions of new data points / sec.
  • Fully Direct3D accelerated and performance optimized
  • Full 64-bit support. Utilizes over 2 GB memory (in 64-bit systems).
  • XY view, 3D view and polar views
  • Various series types: sampled data (discrete data), point-lines, free-form point-lines, stocks, bars, bands, constant lines, 3D bars, 3D point-lines, 3D surface grids, 3D surface meshes, 3D waterfall, polar areas, polar point-lines, polar sectors
  • Built-in series tracking cursors
  • High-capacity 3D surface series, with plentitude of height-coloring, wire-framing, contouring and lighting options
  • Surface mouse tracking and value solve
  • Series and chart event marker indicators
  • Many Y axes/chart: stacked or layered
  • Different X-axis real-time monitoring scrolling modes: Scrolling, sweeping, stepping, oscilloscope style level triggered
  • Automatic scale fitting, grids and divisions
  • Logarithmic axes
  • Fast scale setting with mouse
  • Zoom and pan operations in XY view
  • Zoom, pan and rotate operations 3D view
  • Comprehensive user interface customization: Fonts, alpha colors, line styles, point styles, bitmaps, fills, blinking effects, anti-aliased lines
  • Scrollbars with 64-bit value range

ChartManager is a component coordinating the interoperation of multiple LightningChart Ultimate components. For example it allows for series drag-drop from one chart to another.

SignalGenerator is a multi-functional signal generator component. It allows combining different waveform types into single, real-time output signal. The waveform components can be set with a built-in user interface or by code.

Waveform types

  • Sine: adjustable Amplitude, offset, frequency and delay
  • Square: adjustable Amplitude, offset, frequency, delay and symmetry
  • Triangle: adjustable Amplitude, offset, frequency, delay and symmetry
  • Noise: random noise with adjustable amplitude and offset

The output signal sampling frequency can be freely set and the operating mode can be selected between threaded and timered modes. Several signal generators can be combined as one, synchronized, multi-channel output via master-slave relationship.

SignalGenerator is a very handy component when developing real-time monitoring solutions, with LightningChart Ultimate or other tools.

SignalReader reads signal files in different formats and generates real-time data stream to be forwarded for example to SampleDataSeries of LightningChart Ultimate. Supported formats: WAV (PCM), sid (biosignal file), ssd (LightningChart Demo application sample data format). Supplies event marker info in certain formats. The playback can be automatically restarted with looping playback option.
