• There are quite a few curve fitting software packages available today. However, only some of them will make fit almost any curve.
  • We are recommending CurvFit, Prism, and SciDAVis for quickly fitting data. They are all helpful tools with several innovative features.
  • Giving Adobe XD a chance will only be an asset to the user. It also supports website wireframing and it allows previewing the results on supported mobile devices.
  • Don’t hesitate to visit our Software Tools & Utilities Hub if you want to find the greatest software choices of the moment.

Curve fitting software packages are specialized programs that apply curve fits to your data sets. If you need to generate graphs, you can also use the built-in Windows 10 Office Excel.

However, if you want to create complex, scientific graphs you should use a dedicated curve fitting software.

What’s the best curve fitting tool to use?

1. Adobe XD

install Adobe XD

Adobe XD is a top vector-based user design tool that is usually known for creating user interfaces for both mobile and web apps.

Therefore, with the help of Adobe XD you can easily create a curve by adding an anchor point where a curve changes direction. Then, you just need to drag the direction lines that shape the curve.

Keep in mind that the length and slope of the direction lines are the ones determining the shape of the curve.

Moreover, you can create a series of smooth curves by dragging the Pen tool from different locations. You may even draw straight lines followed by curves or two curved segments connected by a corner.

Add to the list many curve-fitting features that are readily available in Adobe XD. And as a quick tip, your system can display and print curves so much easier when you draw them using as few anchor points as possible.

Some of the Adobe XD key features you’ll most likely appreciate using are:

  • Supports any type of files from Adobe Photoshop, After Effects, and Illustrator
  • Voice commands may be used to design apps
  • Mac OS and Windows compatibility
  • iOS and Android Adobe XD versions to let you preview the result of work on mobile
  • Compatible with custom plugins to help you gain additional uses

2. CurvFit

CurvFit Windows 10

CurvFit allows you to build and simulate mathematical functions, equations, or curves. The only requirement to use this tool is to already have the Visual Basic Run-Time Redistribution Pack installed on your Windows 10 computer.

CurvFit’s interface is rather old-fashioned, but is pretty intuitive, allowing to easily access all the features. The tool also offers a Tip/Suggestions feature that guides you as you use the tool.

If you’re looking for a curve fitting software for academic purposes, then CurvFit is the right choice for you. It can create algebraic series of data such as Sine, damped Sine, Lorentz, and Exponential.

3. Prism

Prism curve fitting software

Prism is a popular curve fitting software developed by GraphPad. This tool combines scientific graphing, comprehensive curve fitting, statistics, and data organization.

Prism is a tool used mainly by scientists, and undergraduate and graduate students. This fact alone confirms it’s a highly reliable tool and offers a wide array of features that can meet the needs of even the most demanding users.

If you’ve never used Prism before, there’s no need to panic. The Learn feature and Prism’s online documentation plainly explain you the principles of the analysis, helping you better understand the processes and principles of nonlinear curve fitting.

Prism is a useful pedagogical tool at the same same, teaching you what you need to know to analyze your data.

If you’re working on a project that involves several data experiments, Prism can record all your experiments, helping you to visualize the results in time.

You can try Prism for free or buy the tool for prices ranging from $20 for a monthly subscription to $725 for a lifetime subscription.

4. SciDAVis

SciDAVis is the short name for Scientific Data Analysis and Visualization, which is an open-source program for interactive scientific graphing and data analysis.

The tool generates 2D and 3D plots from data that is imported from ASCII files, entered by hand, or calculated using formulas. These plots can then be exported to several bitmap formats such as PDF, EPS and more.

The tool is primarily aimed at high-quality plotting of scientific data. It combines an intuitive, easy-to-use user interface with powerful features such as Python scriptability.

SciDAVis’ main advantage is its emphasis on providing a friendly and open environment for new and experienced users alike.

Thanks to good documentation on all levels, such as user’s manual and tutorials, users can quickly learn to master the tool. Moreover, they can share their experiences on SciDAVis’ forums.
