• Fixed an issue where switching between logarithmic and linear axes would not update the display immediately.
• Adjusted the Axis Inspector layout.
• Improved the crash reporter.

• Logarithmic Axes
  • Lin-Log and Log-Log: OmniGraphSketcher supports logarithmic scales on either or both axes. You can easily switch back and forth between linear and logarithmic axes using new controls in the Axes Inspector. Dragging, nudging, snapping, sketch recognition, axis manipulation, importing, exporting, scale-to-fit, etc. have all been updated to work as you'd expect.
  • Configurable: Logarithmic axes support any mathematically plausible min/max values and tick spacing. (Because zero is infinitely far away in logarithmic space, the min/max values for logarithmic axes must both be more than zero, or both less than zero. OmniGraphSketcher will automatically fix any such issues when switching to a logarithmic axis and will prevent you from accidentally setting parameters that are mathematical impossibilities.)
  • Double precision: To accommodate data sets that span many orders of magnitude, axes and data points now support up to 13 significant digits, and they can hold values as large as 10^300.
  • Scientific notation: To accommodate these large numbers, both linear and logarithmic axes now automatically use scientific notation ("1.23 x 10^45") when values are larger than 10,000,000 or smaller than 0.001. On logarithmic scales, simplified powers of ten are used when possible ("10^9"). You can edit these values or enter new data points by using the shortened "E" notation: "1.23E45" or "6E-7".
  • Line interpolation: Lines in OmniGraphSketcher are defined to connect two or more data points as smoothly as possible, regardless of the axis type. The underlying data points are mapped accurately to linear or logarithmic space, but intermediate points on the line are not comparable. To accurately map a line's shape between linear and logarithmic axes, you can now choose: Arrange > Interpolate Line, which will sample along the vertical grid lines (x-values). Now when you switch to a logarithmic axis, you will see how each part of the shape adjusts to logarithmic space.
• Tick Labeling
  • When there is not enough room to label every tick mark, tick labels are now always evenly spaced (skipping tick marks in multiples of two, five, or ten). On logarithmic axes, tick marks representing powers of ten are most likely to be labeled.
  • Where there are at least 5 tick marks between tick labels, OmniGraphSketcher now uses major/minor tick marks to distinguish between labeled ticks (long) and unlabeled ticks (short). This works even if tick labels are not visible.
  • Thanks to these improvements, automatic tick spacing is now 1 in more cases, allowing more easily understandable scales.
  • Tick labels (and everything else in the app that displays numeric data values) now choose an appropriate number of significant digits based on the range of each axis. For example, an axis spanning 0 to 100 will display up to four significant digits ("1.234" or "93.47"); whereas an axis spanning 842 to 843 will use up to six significant digits ("842.551"). This is just for display; all data points are stored with full precision.
• Miscellaneous
  • New menu option: Arrange > Add Jitter (cmd-shift-J) applies a small amount of random vertical noise to the selected data points, using a standard normal distribution. This can be useful for making data points visible that might be hidden behind each other. Apply it multiple times to increase the amount of jitter.
  • Data importing and the Scale to Fit command now choose better automatic axis ranges.
  • Tick label distance and axis title distance are now recorded as part of the "Make Current Styles Default" command.
  • Automatic margins now take into account any arrowheads on the ends of axes.
  • Lines with straight segments at sharp angles now have gentler, rounded joints.
  • Grid lines now adjust to the nearest pixel so that they look sharper on-screen.
  • Fixed an issue where the version number in the About OmniGraphSketcher panel was sometimes in the wrong place.
  • Fixed several issues that could occasionally lead to crashes when reverting, closing, or switching between documents.
  • Smaller fixes and improvements.

• The "Connect Points" button on the data inspector now automatically adds selected points to an existing line if at least one of the points in the existing line is also selected. Also, if there is one line on the graph and nothing selected, the button will now add any unattached points to the existing line.
• The data importer now recognizes data series that don't have any values until near the bottom of their columns. Previously, the importer required all data columns to include at least one numeric value within the first 30 rows.
• Fixed an issue where OmniGraphSketcher 1.1.2 could fail to open graphs with corrupted tick labels.
• Fixed an issue where the error bar creation sheet formatted numbers inconsistently in some regions.
• Fixed an intermittent text spacing issue in the "About OmniGraphSketcher" panel.

• When you drag the axis or axis tick labels in order to change the range, the axis no longer flickers when it snaps to tick marks.
• The data importer now supports numbers formatted with half-spaces as the thousands separator.
• Fixed an issue where closing a graph window after reverting to saved could cause the application to crash.
• Fixed an issue where labels snapped to bar chart bars would always appear above the bar after saving and reopening the graph.
• Fixed an issue where tick labels at the origin could sometimes display "-0".
• Improved the appearance of axes when they are selected.
• Improved application performance and graph file size when changing frequently between different axis ranges.
• Fixed an issue where deleting an axis title and then Undoing the change did not immediately update the graph display.
• Exporting a graph no longer marks the document as unsaved.
• Smaller fixes and improvements.

• Internationalization
  • Added Japanese and French localizations.
  • Improved the experience of typing Japanese characters into text labels.
• Data Importing
  • Improved support for international number formats when importing data and viewing it in the data inspector. OmniGraphSketcher now fully respects the settings in System Preferences > Language and Text > Formats.
  • When you copy data points from OmniGraphSketcher into another program, any labels attached to those points are now included. OmniGraphSketcher can also now import data labels regardless of whether they come before or after the number columns.
  • "Paste as Line" menu item now works for points copied from OmniGraphSketcher (not just data imported from other applications).
• Miscellaneous
  • When you connect a colored data series with a line, the line now becomes the same color as the data points.
  • Added support for storing CMYK colors natively. The CMYK sliders no longer behave strangely when modifying the color of graph objects.
  • Improved rendering of arrowheads for 1-pixel-thick lines.
  • Improved the precision of best-fit line parameter calculation.
  • When the graph window is translucent, the window's shadow now always matches the graph contents.
  • When error bars are created from points that have the same y-value but different colors, the black color is now chosen for the error bar lines.
  • Fixed an issue where Undoing lines or fills under certain circumstances caused the application to crash.
  • Updated the keyboard shortcuts reference document.
  • To reduce screen clutter, release notes no longer open automatically.
  • Smaller fixes and improvements.

• New Features
  • Error Bars: Creating error bars to visualize uncertainty in the data used to be tricky and a bit tedious. A new Make Error Bars menu item can convert existing parallel data series into error bars, or it can create error bars with positive and negative offsets that you specify. See the Help documentation for more examples and information.
  • Support for LinkBack in copied graphs: When you choose "Copy As Image" and paste into a LinkBack-compliant application (such as OmniGraffle and OmniOutliner), you can now go back later to edit the graph by simply double-clicking the image. OmniGraphSketcher will open the graph and save any changes back to the containing document.
  • Tracing: Need to make a nicer version of an existing graph image? You can now make the OmniGraphSketcher window transparent in order to draw directly on top of the source. (You'll find this option in the View menu and the Canvas Inspector.)
  • You can now drag axis titles anywhere along the axis. They will automatically snap to the centered position.
  • You can now create a copy of any set of graph objects by holding down Option as you drag. You can also choose Edit -> Duplicate.
  • You can now use Tab or Shift-Tab to jump to the next or previous text label on the graph. This makes it particularly easy to batch-edit axis tick labels.
  • New option to export graphs in EPS (Encapsulated PostScript) format.
  • New, printable Keyboard Shortcuts page (you'll find it in the Help menu).
• Improved Functionality
  • Improved the auto-scaling behavior when importing data so that it is more likely your axis ranges will automatically be what you expect. This should reduce the need to choose Scale To Fit Data as a manual step.
  • The data importer now recognizes semicolons (;) and pipes (|) as possible separators between data values. Tab and comma separators (or a period (.) in some locales) continue to work as before.
  • Automatic point snapping now works consistently across the Modify, Draw, and Fill tools. It also now supports the situation where you want a line or fill edge to be simultaneously vertical (or horizontal) and snapped to another line (such as a data series). You can just move the point near the location where you want it to snap, or hold down the Shift key to force a horizontal or vertical constraint as part of the snap.
  • When you drag to make a rectangular selection in Modify mode, you will now select all graph objects that overlap the selection rectangle. Hold down the Option key to only select objects fully contained in the rectangle.
  • You can now drag axis ends (or any axis tick label) to scale the axis while the opposite end stays fixed.
  • When dragging the bottom-right window corner to resize the canvas, it will now snap to a square grid -- i.e. make the grid spacing the same on both axes.
  • Whether you're drawing lines, making fills, or editing text, you can now hit Return to confirm edits in progress, or hit Esc to cancel them.
  • Now when you select a line and one or more free-floating points, then click one of the line type buttons on the inspector, the points will be added to the line. This is a useful shortcut for adding new points to data series as you get the data.
  • Software Update can now ignore specific updates, and it supports secure and validated software update feeds.
• Visual Changes
  • Axes are now 1 pixel thick by default so as to make the contents of your graphs more prominent by comparison. (Like all other styles, this setting can be changed using "Make Current Styles Default".) Thin axes also now look better on-screen and in exported bitmap formats.
  • Line equations are now shortened when possible (for example, "y = 3x + 0" becomes "y = 3x").
  • The default color for the fifth imported data series is now a slightly lighter purple.
  • The selection highlight now becomes gray on windows that do not have key focus.
• Bug Fixes
  • Improved the behavior of axes and tick labels when only one axis is visible (i.e. for number lines).
  • Data importing can now handle all combinations of parentheses and currency symbols around a number.
  • Line type defaults are now used more consistently throughout the application (for example, when performing "Paste as Line").
  • Fixed a bug where if you clicked to a different window and then back to OmniGraphSketcher before drawing, the first point drawn could be in the wrong place.
  • The image export commands now replace the .ograph extension instead of adding on to it (for example, "lovely.ograph" now exports as "lovely.pdf").
  • Now when you change a value in a text field in the inspector, then immediately move to another inspector control such as a slider, your text field changes will always be confirmed.
  • Axis tick label styles are now saved separately for each axis when using the Make Current Styles Default command.
  • Fixed some intermittent issues with text editing.
  • Improved the behavior of rectangular select with bar charts.
  • Fixed an issue that prevented you from directly adding a label to a fill.
  • Fixed an issue where holding the shift key could interfere with the key shortcuts for switching tools ('d', 'f', etc.).
  • Axis min/max values are now limited to 3 x 10^35, to prevent crashes.
  • Fixed an issue where setting up lines in certain configurations and then deleting them could result in a crash.
  • Fixed an issue where interacting with certain line shapes could cause a crash.
  • Fixed an issue where copying and pasting labels attached to points could cause a crash.
  • Fixed an issue where undo steps could be generated just by hovering the draw tool over an existing point.
  • QuickLook generator is now compatible with Snow Leopard Wiki Server as a standalone plugin.
  • Smaller fixes and improvements.

• Fully compatible with Mac OS X 10.6 Snow Leopard.
• You can now import data that has text labels specified for only some of the rows.
• Axis title styles are now saved separately in Save Current Styles as Default.
• Added a "Select All Fills" menu item.
• Fixed a bug where dragging a single point from a grouped data series could cause the point to get stuck to nearby points.
• Fixed several bugs where Undo had to be invoked more than once to revert a change.
• Fixed a bug where pasting data with the first column all zeroes sometimes caused a crash.
• Smaller fixes and improvements.
