Origin 2021b: A Powerful Data Analysis and Graphing Software

If you are looking for a software that can help you with data analysis and graphing, you might want to check out Origin 2021b. Origin 2021b is the latest version of Origin and OriginPro, a software package that has been widely used by scientists, engineers, researchers, and students for over three decades. In this article, we will introduce you to some of the key features and benefits of Origin 2021b, as well as how to get it and what are the system requirements for running it.

What is Origin 2021b?

Origin 2021b is the latest version of Origin and OriginPro, a software package for data analysis and graphing.

Origin is an application that allows you to import, explore, analyze, and visualize data from various sources, such as text files, Excel files, databases, web pages, etc. You can perform various types of statistical analysis, curve fitting, signal processing, image processing, peak analysis, etc., using built-in tools or custom scripts. You can also create high-quality graphs with various types of plots, such as line, scatter, bar, pie, contour, surface, vector, etc., using customizable templates or your own settings. You can export your graphs as images or embed them in reports or presentations.

OriginPro is an enhanced version of Origin that provides additional features and tools for advanced users who need more specialized analysis or graphing capabilities. Some of the features that are exclusive to OriginPro are:

  • Advanced statistics such as ANOVA, nonparametric tests, survival analysis, etc.

  • Advanced curve fitting such as implicit fitting, global fitting, nonlinear differential equation fitting, etc.

  • Advanced signal processing such as wavelet transform, Hilbert transform, coherence analysis, etc.

  • Advanced image processing such as morphological filtering, edge detection, FFT filtering, etc.3D surface fitting and 3D parametric function plots

  • Cluster and principal component analysis

  • Design of experiments and Taguchi methods

  • Gadgets such as quick peak fitting, quick statistics, etc.

Whether you choose Origin or OriginPro, you can benefit from the powerful data analysis and graphing features that Origin 2021b offers.

Origin 2021b offers many new features and improvements, such as:

Insert map to graph and shapefile import

Origin 2021b allows you to insert a map to your graph and customize its appearance, such as the projection type, the map region, the color scale, the labels, etc. You can also import shapefiles and overlay them on the map to show additional information, such as boundaries, regions, roads, etc. This feature is useful for geospatial data analysis and visualization.

Enhancements to embedded Python

Origin 2021b enhances the integration of Python with Origin, allowing you to use Python scripts to perform various tasks in Origin, such as importing data, manipulating worksheets, creating graphs, running analysis, etc. You can also use Python packages such as NumPy, SciPy, Matplotlib, Pandas, etc., in your scripts. Origin 2021b supports Python 3.9 and provides a built-in code editor with syntax highlighting, auto-completion, debugging tools, etc.

Mini toolbar for 3D graphs

Origin 2021b adds a mini toolbar for 3D graphs that allows you to quickly access common operations, such as rotating, zooming, panning, changing perspective, etc. You can also use the mini toolbar to adjust the lighting, the transparency, the color map, the axis scale, etc., of your 3D graphs. The mini toolbar is dockable and can be moved to any position on the graph window.

Climate data: NetCDF import and matrix analysis and graphing

Origin 2021b supports importing NetCDF files, which are commonly used for storing climate data. You can import multiple NetCDF files at once and select the variables and dimensions that you want to import. You can also import metadata and attributes from the NetCDF files. Origin 2021b also provides tools for matrix analysis and graphing, such as matrix statistics, matrix math operations, matrix transpose, matrix interpolation, matrix contour plots, matrix surface plots, etc. These tools are useful for working with climate data or other types of multidimensional data.

SQLite import and export

Origin 2021b supports importing and exporting SQLite files, which are widely used for storing relational data. You can import multiple SQLite tables at once and select the columns and rows that you want to import. You can also export worksheets or matrices to SQLite tables and specify the table name and column names. This feature is useful for exchanging data with other applications that use SQLite databases.

Enhancements to worksheet calculations

Origin 2021b improves the worksheet calculations by adding new functions and options. Some of the new functions are:

New dialogs for graph and workbook templates

Origin 2021b provides new dialogs for applying graph and workbook templates to your data. You can access these dialogs from the Tools menu or from the context menu of your data. You can preview the templates before applying them, and you can also filter the templates by category, name, or keyword. You can also create your own templates and save them for future use. These dialogs make it easier and faster to apply consistent formatting and settings to your graphs and workbooks.

Data slicer for graphs

Origin 2021b introduces a new tool called data slicer that allows you to interactively select and highlight a subset of data points on your graph. You can use the data slicer to create a rectangular, circular, or polygonal region on your graph, and then adjust its size, position, and orientation. The
