This ASP component draws pie and bar charts and line graphs "on the fly". Output options include GIF, PNG, JPG and bitmap as a stream for BinaryWrite, or as a file. A wide range of properties allow the customisation of colour, size and text style. Built in defaults allow the production of graphs with only a few lines of code. Use random colours if prefered. Produce HTML image maps for the charts. Free trial available.

QPlot: Allow you view or digitize scatter data.
Visualize scatter data starting from your NotePad; Online data coordinates tracking by mouse ; Support extracting data value from existing or published graph, ex. PDF or Word file; It's light-weight, 1MB

LAB Fit is a software for Windows developed for treatment and analysis of experimental data. At LABFit you are able to:

1) Treat similar data;
2) Treat non-similar data;
3) Determine propagated error;
4) Plot 2D and 3D graphs;
5) Execute math calculations (system of equations, roots of function, etc);
6) Curve Fit (almost 500 functions at the library, with 1 and 2 independent
variables, functions finder, rejection of data).

ImageDIG consists of three integrated modules which allow the user to convert 2D flat images into 3D (x,y,z) data or if a graph, convert the graph in image form into 2 dimensional numerical data. The third module is a full analysis plotting utility where the user can import either the 2D or 3D data saved above or import any number of columns of data from a file. The data can then be analyzed using several statistical functions and plotted.

GraphSight Junior is an easy to use freeware handy 2D math-graphing program. It was originally designed to help students and teachers satisfy their day-after-day math plotting needs. It makes it easy to plot and explore common Y(X) = F(X) Cartesian graphs, set text labels on the coordinate plane, zoom or shift a graph with just a single click & move of mouse. The picture can be than exported to a file or windows clipboard as a bitmap.

Graph Digitizer Scout automatically converts hard-copy graphs, oscillograms, charts, plots,
into X,Y. Different recognition methods including manual correction mode. Data can be exported to Excel, CSV format and other applications.

Graph Component provides 2D plotting facilities, it accepts any number of curves and provides user with ability to zoom, resize and print.

Graph Component works in two modes:

Offline Mode
Online Mode

Plotting functions (usual and parametric) with more possibilities.
Differentiation of any order (with simplification). Construction of tangents to the graph. The simple and clear interface with detailed documentation and examples of work.

Powerful but easy-to-use graphing, curve fitting and calculating software. Graphs Cartesian, polar and parametric functions, graphs of tables, implicit functions, inequalities and slope fields. Up to 100 graphs in one window. Calculus features: regression analysis, intersections, derivatives, tangents, normals and more. The program has printing capabilities, multi-document interface, customizable toolbars.

Low cost 2D function plotting software. Use up to 8 functions with cascades. Displays 2 simultaneous plots with cursors positions and deltas. File load, save, and print. Input point overlays for curve fitting. Trig, Ln, Log functions supported.

JFreeChart is a free Java class library for generating charts (GNU LGPL). Support is included for: pie charts, bar charts, line charts, scatter plots, time series charts, candlestick charts, high-low-open-close charts and more. Use in applications, servlets, JSP or applets. Export to PNG, JPEG, PDF, SVG and HTML image maps. Complete source code is included, subject to the GNU LGPL.

Graph Plotter is a powerful tool which can help you to plot and analyze different types of graphs. It is easy-to-use and user-friendly. In addition it can find asymptotes of function, break points, extremums and calculate limit, define integral, derivative of function and more.
