DataGraph is a simple and powerful graphing application for Mac OS X. It is a great companion for Excel, Numbers or any of the big statistical packages. Simple because it is very easy to draw plots, bar graphs, and fit functions. Start typing in data and the graph immediately shows up. Pick from the initial template list and modify the data, change colors, resize easily and interactively. Download DataGraph now and try it out. Once you like it, you can register your copy from within the application or through the on-line store.
Powerful because as you use DataGraph more and more you will see that every aspect can be tweaked, both interactively and by specifying exact values. You can zoom in on a particular spot, attach labels, compute histograms, fit functions, overlay experimental and analytical results. Because of DataGraphs separation of data and graphs you can then very easily create the same graph for different data by just importing or pasting a new data set into the data table.
Worried about hitting the boundary of what DataGraph can after a couple of weeks of using the application? Don't. DataGraph has a lot of functionality and power beneath the clean exterior.
DataGraph includes many common statistical functions such as function fitting, histograms and box plots. You can easily combine data, fitting results and arbitrary analytical functions in the same graph.
DataGraph creates great looking graph with minimal user fidgeting, but allows you full control if you need to. Here DataGraph differs greatly from standard graphing approaches where you end up spending a huge amount of time entering in tick marks, line thicknesses, selecting from menus. DataGraph uses default rules intended to make great looking graphs, with tick locations, label positions chosen using intelligent rules.
