Giới Thiệu · Graph
This program is for drawing graphs of mathematical functions in a coordinate system. Graphs may be added with different color and line styles. Both standard functions, parameter functions and polar functions are supported. It is possible to evaluate a function at an entered point or tracing the function with the mouse. It is possible to add shadings to functions, and series of points to the coordinate system. Trendlines may be added to point series. It is possible to save the coordinate system and everything on it as an image file. It is also possible to copy an image into another program. Text labels may be placed anywhere in the coordinate system.
Version 4.3 adds calculation of the area under parametric functions, the ability to rotate labels freely, new checkboxes in the function list to indicate visibility, faster plotting of equations and inequalities, and a number of other features.
