Oriana 3 version history

Ver. 3.00 - Released 5 February 2009

Ver. 3.01 - Released 27 April 2009

• Fixed a problem where some basic statistics and pairwise comparisons were not being displayed for samples with extremely large concentrations (> 10,000).
• Fixed a problem in drawing raw data graphs that could very rarely result in a “Division by zero” error.
• Minor changes to the Check for Updates facility to avoid problems if the user tries to save the downloaded update to a folder that is not writeable.
• Editing graphs loaded from old desktop files created with Oriana version 2 could cause a “Range check” error. Fixed.
• The Outline Symbol option on raw and scatterplots was sometimes not outlining the symbols. Fixed.
• The von Mises distribution plots were not drawing any grid lines when the Number of Gridlines option was set to Auto. Fixed.

Ver. 3.02 - Released 23 June 2009

• Circular histograms drawn in a counter-clockwise direction had the bars misplaced (they were drawn one class-width too far in the counter-clockwise direction). Fixed.

Ver. 3.10 - Released 21 September 2009

New features:

• Added two new variables types, Circular Proportional and Circular Percentage. These are circular variables, but rather than setting and reporting the angle as values between 0°-360°, the proportion (0-1) or percentage (0-100) of the circumference of the circle are used. For example, an angle of 90° would be a proportion of 0.25 or a percentage of 25. Data are entered or imported in this format and all graphs and statistical results are labeled with these values.
• Added a “No Grid” option to the Minor Divisions option on the Angular Axis options on histogram dialogs to suppress all angular gridlines, even the ones labeled 0, 90, 180 and 270.
• Allowed the Number of Gridlines option to be set to 0 for the Circular grid on circular graphs, and for scatterplot axes.
• Basic statistics now reports standard deviation, standard error & confidence interval for time variables are reported as a time as well as an angle. The new variable types are also reported as both angles and proportion/percent.
• Changed the “Class width” option on histogram dialogs, which set the width of bars on histograms, to “Number of bars”. This lets users specify the exact number of bars. The equivalent class width is also displayed in the native format (either degrees, time, proportion or percentage).
• Added an option to circular graphs to draw a circle showing the critical value of the Rayleigh test. The length of the r vector can then be compared to this circle to assess its significance.

Bug fixes:

• Fixed the Edit Frequency dialog box to not allow invalid angles to be entered.
• Fixed an Access Violation error that could occur when attempting to delete a graph page by right clicking on the tabs at the left.
• The Options|Format dialog box wasn't always reflecting the current status of the Show Seconds option. Fixed.
• Printing of frequency tables wasn't taking the Show Seconds option into account. Fixed.
• Fixed a problem with checking for valid values when doing search and replace on angles.
• Fixed error that could occur when subgrouping variable is changed after a filtering condition has been set.
• Fixed problems in setting the number of gridlines in QQ and von Mises distribution plots.
• If manual scaling was being used in scatterplots and some data values were outside the set range these points would be plotted anyway, but outside of the graph (e.g. below the axis or off to the right beyond the axis). Now fixed so values outside the range are ignored and not plotted.
• Labeling of scatterplot axes for compass variables was wrong - the second North tick at the end of the axis was missing. Fixed.
• Printed frequency tables for histograms weren’t showing the ranges correctly when the “Center bars on zero option” was selected. Fixed.
• Fixed error that could occur when manual scaling scatterplots with very large linear data values.
• Fixed range check error that could occur when a large number of vector pairs were declared.
• Fixed the Define Vector Pair dialog to allow the same linear variable to be used as a vector length with more than one circular variable.
• Settings of the statistics lines colors, thicknesses and styles were not being saved in the desktop file and weren't being undone properly. Fixed.
