What's New in v4.6.9?

- * Bug Fix: There was a major compatibility issue with FireFox

What's New in v4.6.8?

- + Added option to show Grid lines along X and Y axis. The intervals and color can be set manually
- * Now program can automatically determine the potions of axis to display. Unlike earlier version, axes will always be visible irrespective of the plotting range.
- + Added option to show numbers on X and Y axis with fixed intervals.
- * Minor changes in the user interface.
- + Added option to export and import plotting data in co-ordinate plotting mode into .txt and .csv file format.
- * Changes is .sbgf file format. So older saved file will not be working anymore. If you are having any old file, then you can email author at grapher@subhashbose.com for conversion to current version.

What's New in v4.2.3?

- * User inteface improved.
- + Added color-picker, for easy selection of colors.
- + Added detailed help for every feature of Grapher.
- + Added detailed list of all usable functions.
- + Added option for logarithmic scale of X and Y axis.
- * Internal math library updated to support more functions.

What's New in v3.5.1? [To use Grapher v3 click here]

- + Option to show axes on the graph.
- * Customizable color of axis and option to hide axes.

What's New in v3.4.1?

- * Can now properly plot functions having point(s) of discontinuity. In the previous version there was bug in plotting points of discontinuity. It is adviced to manually set the range of Y (instead of 'Auto') while plotting functions having points of discontinuity in the range of X.
- * Bug fix for plotting in ceil() and antilog().

What's New in v3.2.7?

- + Option to plot functions (in Explicit form y=f(x) ).
- + A math library file added for user-friendly handle of log(), ln(), antilog() and constants like 'pi' and 'e'.
- * Grapher Shell and core had major updates.
- * Minor bug fixes.

What's New in v2.5.0? [To use Grapher v2 click here]

- + Option to change coordinate text size.
- + Option to change global text color.
- * Minor tweaks are done for efficient handling of bigger data.

What's New in v2.2.3?

- * Appearance changed.
- + Option to add title on the top of the Graph.
