Vispy plot Line plot and colorbar. widgets. Plot data with different styles. plot import Fig >>> fig = Fig >>> ax = fig [0, 0] # this creates a Total running time of the script: (0 minutes 1. py import sys import numpy as np from vispy import app, scene from vispy. plot. tests. SurfacePlotVisual (x = None, y = None, z = None, colors = None, ** kwargs) # Bases: MeshVisual. app. ‘top’ and ‘bottom’ are placed horizontally, while ‘left’ and ‘right’ are placed vertically label str The label that is to be drawn with the colorbar that provides information about the colorbar. First, import the required VisPy modules and NumPy for generating data: More example scripts are available in the VisPy repository’s example scripts directory. seed (2324) n = 100000 data = np. While one interface may be enough to build a simple visualization, knowing all the interfaces can provide the most flexibility for fully customizing A scatter plot of 2D points with matching histograms. tests package. First, we will import the VisPy library. In this example, we will create a line plot with a colorbar using VisPy. surface_plot module# class vispy. vispy. Keyword arguments passed to the ViewBox super class. Jul 8, 2023 · To get started with VisPy, we’ll create a basic 2D line plot using the following steps: 5. Download Python source code: axes_plot. backends package. Displays a surface plot on a regular x,y grid. app package. Example: VisPy can be used to plot 2D scatter plot of clustered data in an AI model. gloo module to leverage the power of GPU. Applications of VisPy include: High-quality interactive scientific plots with millions of points. Notes This tutorial focus on two main blocks of vispy:. Widget to facilitate plotting. 646 seconds) Download Jupyter notebook: axes_plot. Canvas class. Demonstrates how to identify (pick) markers. util. scene. filter import TurntableCamera (up = 'z', fov = 60) # Simple surface plot example # x, y VisPy strives to provide an easy path for users to make fast interactive visualizations. import numpy as np import vispy. py However, each example builds on the example before it so features and vispy application best practices are improved at the cost of more complex code. Widget. visuals. Here is one way of doing it : 1) Build a class that inherits vispy. backends. test_app module Notes. random. 587 seconds) Download Jupyter notebook: plot. Importing the Necessary Modules. plot as vp np. Picking Markers#. PlotWidget (* args, ** kwargs) [source] ¶ Bases: vispy. Controls: * p - Toggle picking view - shows the colors encoding marker ID * r - Reset marker symbols and colors. May 19, 2025 · VisPy is a high-performance interactive 2D/3D data visualization library. plot import Fig >>> fig = Fig () And then PlotWidget instances are automatically created by accessing the fig instance: Apr 16, 2020 · We can efficiently plot in real time by using vispy. Example:VisPy can be used for rendering a star cluster in 3D space. gloo: low-level OpenGL interfaces; plot: high-level programming interface; The purposes: learning how to tweak low-level gloo, customizing plot functions, especially for triangle or tetrahedron unstructure meshes. VisPy leverages the computational power of modern Graphics Processing Units (GPUs) through the OpenGL library to display very large datasets. Lastly, these examples use PySide2, but the application structure and demonstrated concepts should apply and be transferable to other backends (especially the Qt ones) with only a few exceptions. You can create a Figure, PlotWidget, and diagonal line plot like this: >>> from vispy. Jul 19, 2024 · Typically, a line plot is used in exploratory data analysis to analyze trends over time. Hover markers to change their symbol and color. Parameters: x ndarray | None. To serve as many users as possible VisPy provides different interfaces for differing levels of experience. widget. **kwargs keywoard arguments. ipynb. Then, we will create a figure object using the Fig() function of VisPy, specifying the dimensions of our plot. To use vispy. Download Python source code: plot. empty ((n, 2)) vispy package. Astronomy & Space Science - Ideal for visualizing galaxies, planetary orbits, and space simulations. plotwidget. Parameters *args arguments. Direct visualization of real Total running time of the script: (0 minutes 2. 1. plotwidget module¶ class vispy. tests package; vispy. plot typically the main class Fig is first instantiated: >>> from vispy. However, each example builds on the example before it so features and vispy application best practices are improved at the cost of more complex code. The position of the colorbar with respect to the plot. surface_plot. This object allows us to link our data to shader variables. Arguments passed to the ViewBox super class. 1D/2D array of values specifying the x positions of vertices in the grid. 2) Create an OpenGL Program whose inputs are shaders. qdazoe onqc fzebe ughdeb zgw uzehom fuupfid quounpm wttgy poltpr
