Grapher :: Free Online Graph plotting software.

Grapher is a online Graph plotting software which is capable of plotting any number of (x,y) coordinates. It can also plot any type of function of 'x'. Grapher itself has large number of predefined mathematical functions, operators and constants which can be used while plotting functions.

This software is highly flexible to meet you needs, it has options to change the text size, colors and almost every properties of the plotted graph.

Using Grapher you can easily analyze your plotted Graph, you can optionally show grid lines and/or numbers along axes. For more convenience Grapher will coordinates while mouse is placed anywhere on the graph area.

This software is such programmed that it will have maximum possible accuracy and user friendliness, special algorithm used to work with linear and logarithmic scale. There are options to set "Auto" values, on which the program will automatically decide the best possible value considering various aspects of the graph.
