The program DISGCL is an interpreter based on the data plotting library DISLIN. DISLIN statements can be written to a script file and then be executed with DISGCL, or can be entered in an interactive mode. Similar to programming languages such as Fortran and C, high-level language elements can be used. These are variables, operators, expressions, array operations, loops, if and switch statements, user-defined functions and I/O routines.

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

DISLIN is a high-level and easy to use plotting library for displaying data as curves, bar graphs, pie charts, 3D-colour plots, surfaces, contours and maps. Several output formats are supported such as X11, VGA, PostScript, PDF, CGM, HTML, PNG and TIFF. DISLIN is available for the programming languages Fortran 77, Fortran 90 and C. Plotting extensions for the languages Perl, Python and Java are also supported for the most operating systems.

3D Grapher is a feature-rich yet easy-to-use graph plotting and data visualization software suitable for students, engineers and everybody who needs to work with 2D and 3D graphs. With 3D Grapher you can easily plot the equation and table-based graphs, zoom them, rotate, view at any angle and even animate. You can draw the unlimited number of graphs in one coordinate system to visualize and analyze the domains of functions and their intercepts.

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.

CurveFitter program performs statistical regression analysis to estimate the values of parameters for linear, multivariate, polynomial, exponential and nonlinear functions. The regression analysis determines the values of the parameters that cause the function to best fit the observed data that you provide. This process is also called curve fitting.
