DataGraph 4.1 – Simple and powerful graphing program

DataGraph is a powerful and easy to use graphing and charting application. DataGraph minimizes the fuss and frustration associated with creating clean and accurate publication quality graphs and charts. DataGraph also includes powerful function fitting and statistical analysis capabilities, which enables high quality analysis of the data. Import data from files, paste in numbers from a spreadsheet, and enter them in manually. Export graphics to files, or copy and paste into presentations.

DataGraph allows you to create in few clicks what would take a lot of tinkering to accomplish using most other tools. As you see in the screenshots below, you see the data table, drawing commands and the graph they generate in a single window. Changes in the data or drawing commands are immediately reflected in the graph. The drawing commands give you quick access to the main settings, and you can toggle them open to see all the settings at once.

There are over twenty drawing commands available, and all of them can be used simultaneously, and multiple times. Some draw data from the table, some fit data, compute statistics or are used to annotate or highlight regions of the graph. Everything is specified using exact coordinates so labels will stay at the point where you inserted them even when the axis changes.

DataGraph includes a number of data manipulation actions. You can map columns of data using analytical expressions, sort, filter, search+replace and create sub-tables of data. DataGraph has been highly optimized. Tables can have millions of rows, and drawing commands can handle large data sets at interactive speeds so you can resize a graph with hundreds of thousands of line segments just as easily as one with a few points.

DataGraph even works correctly with multiple formats of calendar dates, such as: “6/15 2002”, “15/6 2002” and “June 15, 2002”, and automatically picks tick marks that go from years, down to minutes and seconds based on the range.

A partial list of DataGraph’s functionality is:

• Column types are number, text, dates, expression.
• Fit functions: line, polynomial, power, exponential and an arbitrary function with undetermined coefficients that will be optimized.
• Pivot Table for data analysis
• Import text files (tab, comma or space separated), netCDF data files, matlab binary files and Cricket Graph data files.
• Export graphics as pdf, eps or bitmaps in any resolution.
• Export animations as QuickTime movies.
• Histogram, including kernel density, and box and whisker plots to analyze distributions.  Compute medians, means, standard deviations, etc.
• Plot, scatter, lines, draw analytic functions that can be changed using sliders. All the standard analytical functions are defined.
• Multiple x and y axis, overlapping (e.g. double y) and side by side.
• CMYK colors
• Unicode support, can write mathematical expressions and easy to add greek characters, superscripts, subscripts.
• Text labels can include statistics and fit results.
• Use a mask to work on a sub set of the data
• Vary point color based on data/labels
• Vary point sizes based on data.

DataGraph is created by the same company that made DataTank, a high end scientific application which won the Apple Design Awards in 2005 as the best Mac OS X Scientific Computing Solution.

WHAT’S NEW

Version 4.1:

Main Changes

• Added the ability to group global variables
• Added a comment block to the global variables

Changes to Drawing Commands

• Added offset to the Box command, can shift box plots so that you can put side by side
• The Pivot command now allows the value column to be a text column
• Added two mapping types to the Pivot command to group by the day of the week
• Added an option for a rounded rectangle for the Region command
• Fixed an issue that happened when you put a range below the grid
• Added an option for the multivariable fit – arbitrary : log values
• The Multivariable fit now allows you to quickly toggle if a variable is used in the fit
• Added an option to the Pivot command to sort categories for text labels
• Changed how the Bars command works for a logarithmic axis
• Added two new error bar styles – diamond and ellipsoid for the Plot and Points commands
• Added a way to specify the width of a the extra axis exactly
• Added a gear menu entry to the Plot command to create a Points or Fit command based on the data
• Added a gear menu entry to the Points command to create a Fit command for the same x-y data

Other Changes

• Added a method to specify the separator between thousands
• Added a new method to define a sub-header in special import – “Does not start”
• Fixed a problem with importing .mat data files
• Fixed issues when you import an Excel document, both when you drag it and import from a single sheet
• Added a “New Document” entry to the context menu in the Dock
• Added a shortcut to create a map column
• Bug fixes, GUI tweaks, and speed-ups
