Version history information

What's New in v5.5.6 ?

- + Graph labels can be added ox X and Y axis.
- + Graph title and labels can be moved or aligned as desired by user. User need to add required number of blank space with the text to align/move the text on the graph as desired. For more details see help on labels and title.
- + User can show the same used labels in the hover coordinate or simple X or Y as before, by disabling/enabling 'Show Labels in Hover box'.
- * Improved many features and core of the Grapher.
- * Fixed some bugs with hover coordintes in special cases.
- * Changed the default configuration settings for grapher. Hover users can still change the setting as required like before.

What's New in v5.0.3 ?

- + Now Grapher can show coordinated when mouse hovers on the Graph, this help in easy analysis of the graph. This fucntionality is fully compatible with log-scale also.
- * All the compatibility issues with different browsers are now removed. It has been successfully tested on IE v6, FireFox v2 and Operea v9
- * Friendly Url function is now improved. Unlike older versions it can now work with single page load.
- + Added option to download and save the plotted Graph image. The image is in PNG format.
- + Added option to have print view for the graph separately.
- + Some changes in the user interface.
- * Now the function, variables and constants are not case-sensitive.
- * In previous version there was a problem in showing numbers along axis on log scale. It has been fixed now.
- * Now grapher can properly analyze the region of discontinuity / undefined portion of a function. Auto range problems for functions with discontinuity has been resolved.
- + A special algorithm has been implemented for showing axes numbers or hover coordinates in log scale. Since log scale is not a linear scale, precession to a fixed decimal point is not adequate to show accurate values. With this new algorithm it will show accurate coordinates all over the graph area.
- * Minor bug fixes including some javascript bugs.
- - Dropped the show co-ordinate option in function plotting mode.

What's New in v4.6.9? [To use Grapher v3 click here]

- * 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 in .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 show coordinates. (coordinates are properly positioned and checked that they don't go outside graph area).
- + 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.
- * Can now handle both GET and POST data.
- + Option to show friendly URL (which is capable to hold whole graph data) using GET.

What's New in v2.0?

- + Option to include point(s) anywhere is the data set.
- * Complete data handling structure updated to have more flexibility. [File saved under previous version will not work under current version]
- + Option to strip empty field pair.
- * Minor bug fix.
