DataGraph for Mac

Product snapshot

DataGraph is a free graphing and statistics application built for macOS. It helps users turn numerical data into polished visualizations quickly, using a straightforward interface and tools tailored for scientific work. The program is suitable for anyone who needs to present quantitative results clearly — from lab researchers to instructors preparing lecture materials.

Core capabilities

• Create high-resolution bar charts, including grouped and stacked variants, for categorical comparisons.
• Generate scatter plots for exploring relationships between variables and identifying outliers.
• Produce line graphs for time-series or trend analysis with multiple series support.
• Enter data manually or import from common formats, then style axes, labels, and markers to match publication or presentation standards.

Analytical and modeling tools

DataGraph includes built-in statistical functions and curve-fitting utilities for deeper analysis. Users can run regressions, compare models, and fit custom functions to data sets, then overlay fit results on plots for instant visual feedback. These tools make it easier to quantify trends and report parameter estimates alongside graphs.

Who benefits most

• Scientists and researchers who need reliable visualization for manuscripts and reports.
• Educators preparing clear, instructional figures for classes or demonstrations.
• Analysts who value a Mac-native, user-friendly environment for turning data into visuals.

Alternative option
