Unicode support, can write mathematical expressions and easy to add greek characters, superscripts, subscripts.Multiple x and y axis, overlapping (e.g.All the standard analytical functions are defined. Plot, scatter, lines, draw analytic functions that can be changed using sliders.Compute medians, means, standard deviations, etc. Histogram, including kernel density, and box and whisker plots to analyze distributions.Export graphics as pdf, eps or bitmaps in any resolution.Import text files (tab, comma or space separated), netCDF data files, matlab binary files and Cricket Graph data files.Fit functions: line, polynomial, power, exponential and an arbitrary function with undetermined coefficients that will be optimized.Column types are number, text, dates, expression.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.ĭataGraph 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.Ī partial list of DataGraph’s functionality is: You can map columns of data using analytical expressions, sort, filter, search+replace and create sub-tables of data. Everything is specified using exact coordinates so labels will stay at the point where you inserted them even when the axis changes.ĭataGraph includes a number of data manipulation actions. Some draw data from the table, some fit data, compute statistics or are used to annotate or highlight regions of the graph. There are over twenty drawing commands available, and all of them can be used simultaneously, and multiple times. The drawing commands give you quick access to the main settings, and you can toggle them open to see all the settings at once. Changes in the data or drawing commands are immediately reflected in the graph. As you see in the screenshots below, you see the data table, drawing commands and the graph they generate in a single window. Export graphics to files, or copy and paste into presentations.ĭataGraph allows you to create in few clicks what would take a lot of tinkering to accomplish using most other tools. Import data from files, paste in numbers from a spreadsheet, and enter them in manually.
DataGraph also includes powerful function fitting and statistical analysis capabilities, which enables high quality analysis of the data. DataGraph minimizes the fuss and frustration associated with creating clean and accurate publication quality graphs and charts. DataGraph is a powerful and easy to use graphing and charting application.
