Use FindGraph. It's quick and easy! FindGraph is a comprehensive, feature-rich graphing, digitizing and curve fitting software specially created for these purposes. Take any graph or data from any source (Web or PDF document, for example), add your comments, and perform any manipulations, like nonlinear regression or curve fitting. Then print your results or export them to Excel or other database.

With the combination of the intuitive interface, online help and wide range of features, FindGraph is a tool that is used effectively by both beginners and experts.

Graphical Interface Intuitive graphical interface enable you to create and edit plots fast and easily.

2D-graphs Straightforward data entry. Data can be entered:
Text files By importing it from ASCII files created by other applications using an Excel-like data import feature;
Excel spreadsheets By importing Excel spreadsheet data;
Cutting and pasting By cutting and pasting it from other Windows based applications;
Digitizing chart and graphs By digitizing screen charts;
Text editor By typing it into a standard spreadsheet interface.
Graphical editor With graphical editor you can easily:
Series of points Add, move, copy and delete points;
Approximation lines Remove and duplicate graphs or approximation lines;
Edit text Add, position and rotate text easily.
Enhanced commentary Draw text commentary along any curve.

Undo/Redo Unlimited Undo/Redo. .

Curve fitting You can specify the unlimited number of points and lines. Their graphs will be plotted in one coordinate system, allowing comparison of empirical and analytical data. Lots of graph and coordinate plane parameters.

Graph types Supported graph types are:
Scatter diagrams and line graphs Scatter diagrams and line graphs;
Density distribution Points density distributions;
Points diagrams Points groups diagrams.

Zoom easy Zoom is possible.

Graphs and approximations The graphs allow total freedom in setting up scales and grids. Log scales for each axis are available.

Graphs and approximations It is possible to create derived datasets by equations, interpolation, curve fitting, and numerical integration and differentiation.

Export to files FindGraph allows you to export information to the other programs and files. Points can be saved to ASCII tables. Regressiion lines, curves, points and commentaries can be saved to XML file.

COM server FindGraph is COM server. This means, that plot can be copied and pasted (embedded) directly into word processors, Excel or drawing programs.

Business graph High-quality graphs are optimized for printing. The program has preview capabilities. The result on the screen is the same as on the report printout (what you see is what you get).

OLE automation The program supports OLE automation and can be built-in to user software. Examples (MS VB, MS VC++) are included. Methods and properties are documented.
help Context-sensitive help for all windows and elements in dialog boxes.
