PlotLab .NET by Mitov Software is a high-performance suite of data visualization components optimized for ultra-fast, multi-threaded real-time data plotting. It is specifically engineered for use cases demanding high-speed streaming data, such as scientific charts, audio analysis, biomedical signals, and FFT spectral results.
Here is how you can set up and add fast plots using the core components of the library. Core High-Speed Components
Scope Component: A scientific chart module tailored for high-speed, multi-channel data plotting.
Waterfall Component: A single-channel chart ideal for rendering FFT or spectrum waterfall results.
MultiWaterfall Component: A component engineered for video color histograms and multi-channel density displays. Step-by-Step Implementation 1. Setup the Environment
Add the PlotLab assemblies to your .NET Windows Forms project toolbox.
Drag and drop the Scope component onto your main form visual surface.
Use the built-in visual property dialogues to customize the axes layout without writing code. 2. Configure High-Performance Channels
To prevent UI lag during high-frequency data bursts, clear the data paths and allocate dedicated hardware channels:
// Access the scope component instance scope1.Channels.Clear(); // Add a high-performance data channel Mitov.PlotLab.ScopeChannel mainChannel = new Mitov.PlotLab.ScopeChannel(); mainChannel.Name = “RealTimeSignal”; mainChannel.Color = System.Drawing.Color.LimeGreen; scope1.Channels.Add(mainChannel); Use code with caution. 3. Inject Streaming Data Instantly
PlotLab relies on fast array-block processing rather than looping through individual points. To add multi-threaded data directly into a channel, pass a data buffer array:
// Generate or capture a block of real-time data double[] buffer = new double[1000]; // … Fill buffer with real-time hardware data … // Fast multi-threaded data injection block scope1.Channels[0].AddData(buffer); Use code with caution. Key Optimization Practices for “Fast” Plots
Enable Downsampling: PlotLab features native automatic downsampling. It decreases the rendered sample footprint on large datasets, preventing GPU choking while retaining signal fidelity.
Leverage Native Multithreading: Keep data processing computations off the UI thread. PlotLab allows background thread pools to stream .AddData() parameters without breaking the UI render engine.
Handle Data Gaps Safely: Instead of resetting the canvas layout during connection losses, toggle the DataGaps capability to visually jump breaks seamlessly. If you’d like, let me know:
What type of application UI are you building? (e.g., Windows Forms, WPF) What is the frequency/volume of data you are plotting?
