Our verdict on TableCurve 2D

TableCurve 2D is Windows desktop software for engineers and researchers who need to model XY data through automated curve fitting. It evaluates built-in linear and nonlinear equation sets, ranks candidate equations with selectable statistical criteria, and supports custom equations. Fit graphs include residuals plus confidence or prediction intervals, helping users inspect model behavior before selecting an equation. Batch processing also supports repeated work across multiple data sets.

Its core strength is the breadth of curve-fitting and data-treatment tools in one desktop workflow. Users can apply smoothing and denoising methods, including Fourier and eigendecomposition approaches, along with splines, smoothing splines, and local regression. The software imports ASCII, Excel, Lotus, Quattro, SigmaPlot, DIF, SPSS, Systat, and dBase formats. External C or FORTRAN functions extend the equation options, while generated function code and reports support handoff into other technical workflows.

TableCurve 2D suits organizations that want specialized equation discovery rather than a broad statistical environment. Purchasing is handled through contact-sales quoting, so buyers should clarify licensing and fit directly with Grafiti LLC. The product runs on Windows as desktop software, with phone and email support rather than 24/7 coverage. Choose it when automated nonlinear fitting, residual review, smoothing, and exportable results are central requirements; consider a broader statistical suite when you need wider analysis capabilities or a non-Windows deployment.
