  | FindGraph 1.955 |   | FindGraph is a comprehensive graphing, curve fitting, and digitizing tool. FindGraph offers 12 generic fits, including linear regression, logistic functions, fourier approximation, rationals, neural networks, B-splines and parametric curves least squares approximations, plus a library of over 300 industry-specific 2D formulas. FindGraph uses the Levenberg - Marquardt non-linear algorithm and the Simplex algorithm to fit data. A built-in Wizard helps to apply different curve fits to discover the model that best describes the data. Peak fitting features are included. The latest version includes a feature that applies Singular Spectrum Analysis (SSA) to reconstruct and to forecast data series. The software enables you to smooth, interpolate, apply FFT and Wavelet filters, subtract, differentiate, integrate, transform data and curves, and to apply Procrustes analysis. The program comes with 200 built-in common graphing 2D functions support for polar, Cartesian, and parametric equations. A built-in Wizard helps to digitize the data. The program supports OLE automation and can be built-in to other software applications. |

 | Global Mapper 10.00 | | Global Mapper is more than just a utility; it has built in functionality for distance and area calculations, raster blending, feathering, spectral analysis and contrast adjustment, elevation querying, line of sight calculations, cut-and-fill volume calculations, as well as advanced capabilities like image rectification, contour generation from surface data, view shed analysis (including Fresnel) from surface data, and triangulation and gridding of 3D point data. Repetitive tasks can be accomplished using the built in scripting language or comprehensive batch conversion functionality. |

 | CalcExp 1.2.374 |  | CalcExp is designed as an alternative to the system build-in calculators. CalcExp runs on Windows 2K/XP/Vista, MacOsX, Linux, and Solaris. The main features are:
1. All-in-one Calculator:
Can be a good alternative to the system build-in calculators and hand-hold calculators. It makes your calculating faster and safer.
2. Powerful Number formatting:
You have many options to choose for formatting the result number, such as: Locales, Fraction Digits, Scientific Notation, Hexadecimal Displaying, etc, while the windows calculator can't do that for you!
3. Friendly User Interface:
Want it always stand on top? or want hide it as a systray icon? yes, you can do that.
Want unlimited undo/redo when editing the expression? Just press Ctrl+Z/Ctrl+Shift+Z.
Want record an expression, then recall it later? Save it in history list.
4. Skin Changeable:
7 Skins(themes) created by professional artists; the font is clear and easy to read.
5. Web Launch:
revolutionary startup manner: Web Launch. It allows you launch CalcExp in a web browser! With just one click, you can install/launch CalcExp on your computer, whatever you working on Windows, Linux, MacOsX, or Solaris.
6. Easy to Use:
View and Edit the expression directly; Avoid making mistakes to it.
7. Custom Functions:
You can define your own Functions and Constants, and use them later like system build-in functions/constants. It saves time and help you work more efficiently.
8. Fully Tested and Safe:
It has passed more than 1141 test cases to make sure your calculation is safe. It comes with a set of Bug Tracing Mechanism to help find any exceptions in calculating and report them to fix at once. This makes CalcExp become safer and safer.
9. Useful Tools:
A great feature of CalcExp is the useful tools, there are good friends in your work. There are 4 useful tools in CalcExp:Unit Converter, Currency Converter, Statistics Calculator, and Color Converter. |

 | Dagra 1.1.7 | | Dagra helps you digitize numerical data from printed graphs. Using Bezier curves, you can quickly and accurately retrieve data from scanned or graphical images. Add-ins for MathCad(R), Excel(R) and Matlab let you quickly load the digitized data into these analysis tools. Dagra lets you access a wealth of printed data for:
- Design calculations
- Numerical modelling
- Simulations
- Control system development
- Comparing new results with previous work.
Extract numerical data from a graph in 3 steps with Dagra:
1. Import the graph
Dagra can import most common image formats (BMP, GIF, JPG, JPEG, PNG, TIFF, WMF, EMF). You can also import images from the clipboard: copy a graph directory from a Acrobat PDF file, for example.
2. Trace the data
Tracing data is quick with Dagra, because you do not have to tediously locate every data point. Instead, Dagra uses Bezier curves that let you quickly fit a smooth, accurate line through any curve using only a few control points. Dagra uses interpolation to find all the points on the curve it needs to accurately describe your data.
3. Export the data
The traced data can be exported to comma or tab delimited text files, which can be imported into most analysis packages. Plug-ins for Microsoft Excel , MathCad and Mathworks Matlab let you import data from Dagra files directly. |
