* Grapher Shell and core had major updates.+ A math library file added for user-friendly handle of log(), ln(), antilog() and constants like 'pi' and 'e'.+ Option to plot functions (in Explicit form y=f(x) ).* Bug fix for plotting in ceil() and antilog().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. In the previous version there was bug in plotting points of discontinuity. * Can now properly plot functions having point(s) of discontinuity.* Customizable color of axis and option to hide axes.* Internal math library updated to support more functions.+ Added option for logarithmic scale of X and Y axis.+ Added detailed list of all usable functions.+ Added detailed help for every feature of Grapher.+ Added color-picker, for easy selection of colors.If you are having any old file, then you can email author at for conversion to current version. So older saved file will not be working anymore. + Added option to export and import plotting data in co-ordinate plotting mode into.+ Added option to show numbers on X and Y axis with fixed intervals.Unlike earlier version, axes will always be visible irrespective of the plotting range. * Now program can automatically determine the potions of axis to display.The intervals and color can be set manually + Added option to show Grid lines along X and Y axis.* Bug Fix: There was a major compatibility issue with FireFox.- Dropped the show co-ordinate option in function plotting mode.* Minor bug fixes including some javascript bugs.With this new algorithm it will show accurate coordinates all over the graph area. Since log scale is not a linear scale, precession to a fixed decimal point is not adequate to show accurate values. + A special algorithm has been implemented for showing axes numbers or hover coordinates in log scale.Auto range problems for functions with discontinuity has been resolved. * Now grapher can properly analyze the region of discontinuity / undefined portion of a function.* In previous version there was a problem in showing numbers along axis on log scale.* Now the function, variables and constants are not case-sensitive.+ Added option to have print view for the graph separately.+ Added option to download and save the plotted Graph image.Unlike older versions it can now work with single page load. * Friendly Url function is now improved.It has been successfully tested on IE v6, FireFox v2 and Operea v9 * All the compatibility issues with different browsers are now removed.This fucntionality is fully compatible with log-scale also. + Now Grapher can show coordinated when mouse hovers on the Graph, this help in easy analysis of the graph.Hover users can still change the setting as required like before. * Changed the default configuration settings for grapher.* Fixed some bugs with hover coordintes in special cases.* Improved many features and core of the Grapher.+ 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'.For more details see help on labels and title. User need to add required number of blank space with the text to align/move the text on the graph as desired. + Graph title and labels can be moved or aligned as desired by user.+ Graph labels can be added ox X and Y axis.Ģ2) Log(x) on log scale Version history information And lots of more options to easily use the program and get exactly what you want.ġ) Plot of square of natural number seriesĥ) Grapher Logo using Grapher ġ1) Plot of sin(x) sin(2*x), having multiple discontinuityġ2) Plot of sin(x) sin(2*x), having multiple discontinuity ġ9) Sin function on log scale.Using friendly url option you can get a unique address for your plotted graph which you can use in other forum or sites as direct link.Plotted graph can be downloaded as portable image format.Plotted graph settings can be downloaded as a file, so that you can save the file for future use.Some of the options can be set to 'Auto' value, so that the program can automatically assign the best possible value.Show / Hide of Grid lines, axes numbers are optional.Title and labels can also be aligned or moves as desired by user. Can show graph title and lables on X and Y axis.All the graph colors including background color, line color, text color, axis color etc can be easily customized. The graph is automatically scaled to cover whole of the graph area.Shows coordinates on placing mouse over the graph.Lots of mathematical and logical functions available to use. Can plot any kind of explicit functions.Can plot any number of (x,y) coordinates.Enter the function to plot, f(x) = Some key features at a glance
