![]() The K-means clustering algorithm is often used to cluster the customer base into discrete customer groups with similar characteristics. Let’s demonstrate it on a simple example. The largest Veusz’s competitive advantage over some other graphic packages is likely its capability to prepare complex 3D graphs. Graph export possibilities include TIFF format and other standard formats (JPG, PNG, and several others). For instance, this piece of code constructs a simple x-squared plot which changes to x-cubed (it is referenced from the official documentation): import veusz.embed as veusz import time # open a new window and return a new Embedded object embed = veusz.Embedded('window title') # make a new page, but adding a page widget to the root widget page = ('page') # add a new graph widget to the page graph = page.Add('graph') # add a function widget to the graph. There is, therefore, another competitor to the standard python libraries such as Matpotlib, Seaborn, or Plotly. Veusz can be used as a Python module for plotting data. The NumPy package is already imported into the command line interface. Veusz can also read Python scripts from files. When commands enter in the command prompt in the Veusz window, it supports a simplified command syntax, where brackets following commands names can be replaced by spaces in Veusz commands. Therefore you can freely mix Veusz and Python commands on the command line. As Veusz is programmed in Python, it uses Python as its scripting language. Command-line interfaceĪn alternative way to control Veusz is via its command-line interface. Properties of widgets are edited in the Properties window, and their appearance and formal side (font, axis line color, color of labels, etc.) in the Formatting window. In Veusz, plots are created by building up plotting widgets, specific elements (charts, axes, text labels, etc.) that the user adds or removes in the Editing window. Manual formatting involves importing data and manual editing graphs to build the 2D or 3D product. Veusz allows formatting graphs in three ways: benefits of using Veusz in comparison with other programs.įinally, I will also mention some drawbacks that the user can find working with the program.Despite all the benefits, it seems that data scientists and researchers are not well-aware of all the possibilities that Veusz provides. Veusz is a simple but powerful tool for preparing high-quality graphics that researchers can use to visualize their results. In academic journals, the editors require highly developed plots, but some statistical programs do not provide good quality graphs for publication in decent journals. With a solid capacity for creating 2D and 3D graphs, Veusz helps researchers visualize all types of data structures they use in social sciences, engineering, biology, medicine, etc. It is freely available and well-integrated with Python. Selecting "xy1" will allow you to set the data for each axis and the display name for the plot key.Veusz is a graphing program designed to produce publication-ready plots for academic and professional journals. ![]() Strain Amplitude, Reversals), set the minimum and maximum axis values, as well as set the axis to display as logarithmic. When selecting "x" or "y", the "Properties" pane will allow you to assign labels to the axes (e.g. Selecting any of these will allow you to format each individually. On the left hand side, you now have a list of elements "x, y, xy1".To plot more than one set of data on a graph, click "Insert -> Add xy" again and this will create a new element "xy2". This will create the element "xy1" where you can link your data to the graph. On the left hand side, highlight "graph1" then click "Insert -> Add xy".Your data should now be visible in the "Dataset" pane on the right hand side. Make sure your data was read correctly and click "Import" on the bottom right of the Import data window. Browse to your formatted data file and click open. Select the tab that corresponds to your data format (e.g. Click "Data -> Import" to open the import data window.Once data is properly arranged, it can be saved as a comma delimited. An example of data formatting is shown in the Excel image below. One of the easiest methods for formatting data to import into Veusz is by using Microsoft Excel.The developer's site, basic tutorials, and a full list of features are available here. In addition, you can also enter, manipulate or examine data from within the application. ![]() Data can be read from text, CSV, HDF5 or FITS files. The program runs under Unix/Linux, Windows or Mac OS X, and binaries are provided. SVG, EMF and bitmap export formats are also supported. It is designed to produce publication-ready Postscript or PDF output. Veusz is a GUI scientific plotting and graphing package. ![]()
