We're still working on adding great features like automatic creation of Error Bars to OmniGraphSketcher 1.1, but in the meantime we're putting out version 1.0.1 to ensure compatibility with any forthcoming OS X updates from Apple. In addition, this release features quite a few bug fixes, adds a “Select All Fills” menu item, and gives users the ability to import data that has text labels specified for only some rows.
