• Revised data grid to improve performance and editing.  Fixed a bug in date conversion also.
• Turbo Grapher now saves basic grid formatting features like column width, alignment, etc.  You can also specify display formatting and can lock cells from editing.
• Added a dynamic zoom and scroll feature which allows you to rescale a graph's plot area using the mouse. See the Help files keyboard section. 

• Added menu bitmaps.
• Optimizations to math engine
• Added additional features to polynomial derivative plots.
• more .......

• Modified data grid to simplify data entering.  Also added ability to paste space-delimited text.
• Added ability to select derivative plots for polynomials. You can choose from first order to third order plots.
• Revised autoscaling slightly.
• Added option to select a default menu arrangement.

• Fixed problem with pasting external data into the data grid.
• Add "Marker" points which allow you to mark and edit graph data points directly on the screen page.  For practical reason, this will only work with the first 100 points of data. Please note that Turbo Grapher does not save data changes as part of the UNDO engine. All modification to data points will need to be restored manually if required.
• Enhanced the Quick Calc and the Plot Size Dialogs.  You can now change the width and height of the plot area by using the mouse.
• Significantly improved the color palette function.  You can now create new palettes and save them.  Modified palettes are remembered for the entire session. NOTE: The palette dialog will occassionally crash after repeated importing or palette changes.   Item is being worked on.
• Many graph dialogs, including the Quick Calc and Plot Size features, now utilize a new graphing custom control we have created.  This control has many internal features which allow editing and manipulating graphs easier.
• Enhanced Keyboard function.  Check the new help file for info.

• Changed the update installer so you can choose the installation path.
• Added "Trace Current Plot Series" which creates a polyline from the selected graph.
• More tweeks to the graph engine.
• Added a Preference dialog to the data grid which allows you to set some colors and grid font.
• The data grid mouse selection now will highlight correctly when dragging in any direction.

This is a HIGHLY recommended patch for all Users of V3.x

• Fixed problem with data grid where it would not paste delimited text correctly.
• Fixed problem with Cumulative frequency plots. Previously would not generate curve properly.
• Dramatically improved scrolling and screen regeneration speed.
• Fixed bug where plot series with many points would obscure the series line type.
• Improved graph redraw speed for X-Y plots.
• Added option to Polynomial Fit setup dialog to view detailed calculations.  This allows you to access residual values for the curve fit.
• Added "Zoom Up" and "Zoom Down" buttons which increment zooming by 10%.
• Improved screen handling of polylines and polygons.

• Revised Manning calculation dialog for irregular channels.  Turbo Grapher now detects the channel elevation based on the data and calculates from that.  Originally the base elevation was assumed to be zero.
• Added full functionality to scroll bars.  Also can use Page Up/Page Dn. keys to scroll.
• Can use arrow keys to move selected objects.
• Created a new TGC file which can dramatically reduce the size of project files. See help file for more info.
• Updated help file to cover the new Analysis tools.

• Revised print engine.  Turbo Grapher now saves a complete printer profile with each project.  This allows easy use & saving of printer specific features.  If you load a project file on a system without the printer which was used to create the document, the default system printer is used.  This revision also fixed a problem where printer names longer than 32 characters would cause Turbo Grapher to bomb.
• Added a "Document Properties" sheet.  This allows you to specify an author, track revisions, etc.
• Added "Make Identical" for graph objects. See help file.
• Added a whole section of Analysis/Engineering tools.  This is an ongoing project.   So far you can use several hydraulic analysis features such as Manning calculations and pump curves.  This "Toolbox" will be expanded more over time to include many useful engineering & analysis tools.
• Fixed bug in "Combine Graphs" function.
• Numerous other patches & fixes.
• Updates to help file.  The help file is still incomplete however.

• Fixed redraw problem while creating new lines, polylines & arrows.
• Tweaks to Help File.

• Progress Bar dialog would not display.  This has been corrected.
• Solved some mouse handling issues with arrows & lines.
• Updates to help file.

• Initial Release
