OmniGraffle excels at creating flow charts, system diagrams, and layouts. OmniGraphSketcher is designed for creating quantitative diagrams (graphs). You can do a lot with both though!

OmniGraphSketcher is not a function graphing program (try Grapher in Mac OS X Tiger and Leopard). And although it does have some convenient calculation abilities, it is by no means a math or stat package (try Mathematica). Finally, although it contains a mini spreadsheet, it is not Numbers or Excel. Instead, OmniGraphSketcher combines just enough pieces from all of these worlds to let you make graphs fast and furiously.

Not currently. In most cases, information that you might want to display in a pie chart is better displayed in a bar chart or table. We’re committed to staying true to best practices for data visualization whenever possible.

OmniGraphSketcher will import directly from any other application (such as a spreadsheet or text editor). Just copy and paste the data right into the graph window.

Specifically, tab- or comma-separated values are imported as follows:

• 1 column of numbers: 1-dimensional data (series plot).
• 1 column of labels, 1 of numbers: axis tick mark labels with 1-D data (series plot).
• 2 columns of numbers: 2-dimensional data (scatter plot).
• 1 column of labels, 2 of numbers: 2-D data (scatter plot) with a label for each data point.
• More than two columns of numbers: 2-D data, with the first column repeated as a pair with each other column.

We released OmniGraphSketcher 1.2, featuring log axes, in August 2011. If date and time axes are on your wish list, please send us feedback!

Not currently. Most of the time this type of graph offers no improvement in readability over two graphs arranged vertically with identical x-axes. There’s more information in this blog post written by OmniGraphSketcher lead engineer Robin.

We’ve added a lot since the last release of Graph Sketcher (1.5.2), including a new user interface, complex curved lines, adjustable margins, and importing of multiple data series. For more detailed information, check out the archived release notes in the OmniGraphSketcher help menu.

Like most Mac OS X applications, our products can be uninstalled by simply dragging the icon to the trash. Once you empty the trash, the application is gone from your computer. Like Jeff Goldblum says, “There is no step three!”.

Just visit the Lost Licenses page to retrieve it. If this does not work for you, please send an email to sales@omnigroup.com.

If you purchased your license through our online store:
Both the license key and license owner must be entered exactly as it was emailed to you. The key is linked to the owner so they both must match exactly to be accepted by the application. The license key should be a 23-character long string and does not contain numbers. If you need your license key sent to you again, you can use the Lost Licenses page to retrieve it. If you are still having trouble, please send an email to sales@omnigroup.com.

If you purchased a retail boxed copy:
Please double check you entered the license key exactly as given to you. The license key should be a 23-character long string in the format of XXXX-XXXX-XXXX-XXXX-XXXX-XXX and does not contain numbers. If you are still having trouble, please send an email to sales@omnigroup.com. It is also recommended you register your license key with us so we can send it to you if you happen to misplace it.

One of the advantages of the Mac App Store is that the products you buy there don’t require license codes. Instead, your iTunes account information is used to unlock the products you buy there.

If your Omni application is asking for a license code, it’s usually because a trial copy of the application downloaded from our website is being run instead of the Mac App Store edition.

The easiest thing to do in this case is a Spotlight search of the entire Mac for the product name. Use the results to find and launch each copy of the app on your Mac one by one. If a copy asks for a license, quit it, then move it to the Trash. Copies installed via the Mac App Store won’t do this.

If, at the end of this process, all the copies are in the Trash, you can use the “Purchases” tab in the Mac App Store to download a new copy of the product. Once the Mac App Store edition is installed, you won’t be asked for the license info on launch.
